General Description: The single and dual channel Switch/Proximity Detector Interface, D5034S and D5034D is a high integrity repeater, designed to interface contacts or proximity
detectors (EN60947-5-6, NAMUR) located in Hazardous Area and is suitable for applications requiring SIL 3 level (according to IEC 61508:2010 Ed. 2) in safety related systems for
high risk industries.
Field loop integrity and status (line plus contact or proximitor) are continuously and directly monitored, in transparent mode, into the PLC, ESD, DCS using their existing input line,
without requiring an additional channel for line fault detection.
PLC / DCS can detect the following conditions:
0.5 to 1.3 mA Input open condition
2.0 to 6.0 mA Input close condition
0 to 0.4 mA Input fault condition (Line break)
6.5 to 8.0 mA Input fault condition (Short circuit)
These are automatically detected for proximity switches inputs.
For contact inputs is necessary to install end of line resistors close to the contacts.
Mounting on standard DIN-Rail, with or without Power Bus, or on customized Termination Boards, in Safe Area or in Zone 2.
Functional Safety Management Certification:
G.M. International is certified by TUV to conform to IEC61508:2010 part 1 clauses 5-6 for safety related systems up to and included SIL3.

Safety Function and Failure behavior:
D5034 is considered to be operating in Low Demand mode, as a Type A module, having Hardware Fault Tolerance (HFT) = 0.
The failure behaviour is described from the following definitions :
fail-Safe State: state is defined as the output going Low or High, considering that the safety logic solver can convert the Low or High fail (dangerous detected) to the fail-safe state;
fail Safe: failure mode that causes the module to go to the defined fail-safe state without a demand from the process;
fail Dangerous: failure mode that does not respond to a demand from the process (i.e. being unable to go to the defined fail-safe state) or deviates the output current by
more than 5% (0.4 mA) of 8 mA full scale;
fail High: failure mode that causes the output signal to go above 7 mA (as short circuit of input). Assuming that the application program in the safety logic solver is
configured to detect High failure and does not automatically trip on this failure, this failure has been classified as a dangerous detected (DD) failure.
fail Low: failure mode that causes the output signal to go below 0.35 mA (as input line breakage). Assuming that the application program in the safety logic solver is
configured to detect Low failure and does not automatically trip on this failure, this failure has been classified as a dangerous detected (DD) failure.
fail “No Effect”: failure mode of a component that plays a part in implementing the safety function but that is neither a safe failure nor a dangerous failure. When calculating the
SFF, this failure mode is not taken into account;
fail “Not part”: failure mode of a component which is not part of the safety function but part of the circuit diagram and is listed for completeness.
When calculating the SFF this failure mode is not taken into account.
The 2 channels of D5034D module could be used to increase the hardware fault tolerance, needed for a higher SIL of a certain Safety Function, as they are completely independent
each other, not containing common components. In fact, the analysis results got for D5034S (single channel) are also valid for each channel of D5034D (double channel).
Failure rate date: taken from Siemens Standard SN29500.
Description:
The module is powered by connecting 24 Vdc power supply to Pins 5 (+ positive) - 6 (- negative). The green LED is lit in presence of supply power.
Voltage free contact or proximity detector are applied to Pins 7-8 (In 1 - Ch.1) and Pins 9-10 (In 2 - Ch.2).
Sink output currents are applied to Pins 1-2 (for Channel 1) and Pins 3-4 (for Channel 2).

The proof test shall be performed to reveal dangerous faults which are undetected by diagnostic. This means that it is necessary to specify how dangerous undetected faults, which
have been noted during the FMEDA, can be revealed during proof test.
Note for switch input: to detect a broken wire, or a short circuit condition, in the input connections it is necessary to mount, close to the switches, the end of line resistors:
R1=1 Ktypical (470 to 2 Krange) resistor in series and R2=10 ktypical (5 Kto 15 Krange) resistor in parallel to the contacts.
The Proof test 1 consists of the following steps:
Testing procedure at T-proof
Steps Action
1 Bypass the safety-related PLC or take other appropriate action to avoid a false trip.
2 Vary the state condition of the input sensors /contacts or the proximity switches connected in the field in order to go to short circuit condition and verify that
the output current of the repeater reaches high current value (> 7 mA). This test for compliance voltage problems such as a low loop power supply voltage or
increased wiring resistance.
3 Vary the state condition of the input sensors / contacts or the proximity switches connected in the field in order to go to open connection condition (equivalent to
line breakage) and verify that the output current of the repeater reaches low current value (< 0.35 mA). This tests for possible quiescent current related failures.
4 Restore the loop to full operation.
5 Remove the bypass from the safety-related PLC or restore normal operation.
This test will reveal approximately 99 % of possible Dangerous Undetected failures in the repeater.
Steps Action
1 Bypass the safety-related PLC or take other appropriate action to avoid a false trip.
2 Perform step 2 and 3 of the Proof Test 1.
3 Connect an ammeter in series to the input sensors / contacts or the proximity switches in order to measure the input sensor current. Then vary the state
condition of the input sensors / contacts (from open to close condition and vice versa) or the proximity switches (from ON to OFF condition and vice versa),
and verify that the output current of repeater is in accordance with the input sensor current, within the specified accuracy.
This requires that the input sensors / contacts or the proximity switches have already been tested without the repeater and they work correctly according to
their performance.
4 Restore the loop to full operation.
5 Remove the bypass from the safety-related PLC or restore normal operation.
This test will reveal approximately 30 % of possible Dangerous Undetected failures in the repeater.
The Proof test 2 consists of the following steps:

D5034 series are isolated Intrinsically Safe Associated Apparatus installed into standard EN50022 T35 DIN-Rail located in Safe Area or Zone 2, Group IIC, Temperature T4,
Hazardous Area (according to EN/IEC60079-15) within the specified operating temperature limits Tamb –40 to +70 °C, and connected to equipment with a maximum limit for
AC power supply Um of 250 Vrms.
Not to be connected to control equipment that uses or generates more than 250 Vrms or Vdc with respect to earth ground.
D5034 series must be installed, operated and maintained only by qualified personnel, in accordance to the relevant national/international installation standards (e.g. IEC/EN60079-14
Electrical apparatus for explosive gas atmospheres - Part 14: Electrical installations in hazardous areas (other than mines)), following the established installation rules, particular care
shall be given to segregation and clear identification of I.S. conductors from non I.S. ones.
De-energize power source (turn off power supply voltage) before plug or unplug the terminal blocks when installed in Hazardous Area or unless area is known to be nonhazardous.
Warning: substitution of components may impair Intrinsic Safety and suitability for Zone 2.
Explosion Hazard: to prevent ignition of flammable or combustible atmospheres, disconnect power before servicing or unless area is known to be nonhazardous.
Failure to properly installation or use of the equipment may risk to damage the unit or severe personal injury.
The unit cannot be repaired by the end user and must be returned to the manufacturer or his authorized representative.
Any unauthorized modification must be avoided.
Warning
Operation
The single and dual channel Switch/Proximity Interface, D5034S and D5034D is a high integrity repeater, designed to interface contacts or proximity detectors (EN60947-5-6, NAMUR)
located in Hazardous Area and is suitable for applications requiring SIL 3 level (according to IEC 61508:2010 Ed. 2) in safety related systems for high risk industries.
Field loop integrity and status (line plus contact or proximitor) are continuously and directly monitored, in transparent mode, into the PLC, ESD, DCS using their existing input line,
without requiring an additional channel for line fault detection.
PLC / DCS can detect the following conditions:
0.5 to 1.3 mA Input open condition
2.0 to 6.0 mA Input close condition
0 to 0.4 mA Input fault condition (Line break)
6.5 to 8.0 mA Input fault condition (Short circuit)
These are automatically detected for proximity switches inputs. A “POWER ON” green led for each channel lits when input power is present.
Note: use of voltage free electrical contacts with fault detection enabled (control equipment) requires, near the switch at the end of the line a R1=1 Ktypical (470 to 2 Krange)
resistor in series and a R2=10 ktypical (5 Kto 15 Krange) resistor in parallel to the contacts in order to allow the fault detection circuit to distinguish between a condition of
contact close/open and a line open/short circuit fault.
Installation
D5034 series are Switch/Proximity Detector Interface housed in a plastic enclosure suitable for installation on T35 DIN-Rail according to EN50022, with or without Power Bus or
on customized Termination Board.
D5034 unit can be mounted with any orientation over the entire ambient temperature range.
Electrical connection of conductors up to 2.5 mm² are accommodated by polarized plug-in removable screw terminal blocks which can be plugged in/out into a powered unit without
suffering or causing any damage (for Zone 2 installations check the area to be nonhazardous before servicing).
The wiring cables have to be proportionate in base to the current and the length of the cable.
On the section “Function Diagram” and enclosure side a block diagram identifies all connections.
Identify the number of channels of the specific card (e.g. D5034S is a single channel model and D5034D is a dual channel model), the function and location of each connection terminal
using the wiring diagram on the corresponding section, as an example:
Connect 24 Vdc power supply positive at terminal “5” and negative at terminal “6”.
For Model D5034S connect positive output of channel 1 at terminal “1” and negative output at “2”.
For Model D5034D in addition to channel 1 connections above, connect positive output of channel 2 at terminal “3” and negative output at “4”.
For Model D5034S, in case of Proximity or Voltage free Contact, connect the wires at terminal “7” for positive and “8” for negative.
For Model D5034D in addition to channel 1 connections above, connect terminal “9” for positive and “10” for negative on channel 2.
Intrinsically Safe conductors must be identified and segregated from non I.S. and wired in accordance to the relevant national/international installation standards (e.g. EN/IEC60079-14
Electrical apparatus for explosive gas atmospheres - Part 14: Electrical installations in hazardous areas (other than mines)), make sure that conductors are well isolated from each other
and do not produce any unintentional connection.
The enclosure provides, according to EN60529, an IP20 minimum degree of mechanical protection (or similar to NEMA Standard 250 type 1) for indoor installation, outdoor installation
requires an additional enclosure with higher degree of protection (i.e. IP54 to IP65 or NEMA type 12-13) consistent with the effective operating environment of the specific installation.
Units must be protected against dirt, dust, extreme mechanical (e.g. vibration, impact and shock) and thermal stress, and casual contacts.
If enclosure needs to be cleaned use only a cloth lightly moistened by a mixture of detergent in water.
Electrostatic Hazard: to avoid electrostatic hazard, the enclosure of D5034 must be cleaned only with a damp or antistatic cloth.
Any penetration of cleaning liquid must be avoided to prevent damage to the unit. Any unauthorized card modification must be avoided.
According to EN61010, D5034 series must be connected to SELV or SELV-E supplies.
End of Line Resistor for Contact
Start-up
Before powering the unit check that all wires are properly connected, particularly supply conductors and their polarity, input and output wires, also check that Intrinsically Safe conductors
and cable trays are segregated (no direct contacts with other non I.S. conductors) and identified either by color coding, preferably blue, or by marking. Check conductors for exposed
wires that could touch each other causing dangerous unwanted shorts. Turn on power, the “power on” green leds must be lit output condition must be in accordance with condition of the
corresponding input line. If possible close and open input lines one at time checking the corresponding reflected current output to be correct.
Use of voltage free electrical contacts with fault detection enabled (control equipment) requires, near the switch at the end of the line a 1 Ktypical (470 to 2 Krange) series
connected resistor and a 10 Ktypical (5 Kto 15 Krange) parallel connected resistor in order to allow the fault detection circuit to distinguish between a condition of contact
close/open and a line open/short circuit fault.
