General Description: The D5293S is a relay module suitable for the switching of safety related circuits, up to SIL 3 level according to IEC 61508:2010 Ed.2, for high risk industries. It
provides isolation between input and output contacts. A wide compatibility towards different DCS/PLC is guaranteed: driving line pulse testing, executed by DCS/PLC, is permitted by a
dedicated internal circuit, to prevent relay and LED flickering. D5293S provides 1+1 SPST contact for normally energized load. SIL 3 Safety Function for NE load (de-energized in fail
safe state) is available at Terminal Blocks 13-14. When the driving signal is high (24 Vdc), the relay is energized (normal state), SIL 3 contacts at terminals 13-15 and 14-16 are closed,
the load is energized. The safety function is met when the driving signal is low (0 Vdc), the relay is de-energized (fail safe state), SIL 3 contacts at terminals 13-15 and 14-16 are open,
the load is de-energized. Load is isolated from supply on both polarities: +/AC, -/AC.
Load and Line Diagnostic: Line and load short/open circuit detection is provided. Load RMS voltage and current are measured by the module. Load voltage and current can automati-
cally be acquired from field. User configurable limits set the minimum and maximum values of supply voltage (DC or AC) and load current.
The fault in the field is directly mirrored to the PLC DO: few systems may exceptionally require an external resistor at terminals 7 and 8.
All diagnostic conditions, that detect a fault on line and load, open the fault relay contacts and are also available from a RS485 Modbus output to identify any specific fault.
Diagnostic functions with fault relay NO contacts are SIL 2 rated according to IEC 61508:2010 Ed.2 (Route 2H).
Mounting on standard DIN-Rail, with or without Power Bus, or on customized
Termination Boards, in Safe Area / Non Hazardous Location or in Zone 2 / Class I, Division 2 or Class I, 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.
The module is fully programmable to set the operation parameters from PC by the GM Pocket Portable Adapter PPC5092 via USB serial line and SWC5090 Configurator software.
Measured values and diagnostic alarms can be read on both serial configuration or Modbus output line.

Warning
Operation
The single channel 5 A Relay Output D5293S is a relay module suitable for the switching of safety related circuits, up to SIL 3 level according to IEC 61508:2010 Ed. 2 for high risk
industries. It provides isolation between input and output contacts. D5293S has 1+1 SPST contact for normally energized load. SIL 3 Safety Function for NE load (de-energized in fail
safe state) is available at Terminal Blocks 13-14. When the driving signal is high (24 Vdc), the relay is energized (normal state), SIL 3 contacts at terminals 13-15 and 14-16 are closed,
the load is energized. The safety function is met when the driving signal is low (0 Vdc), the relay is de-energized (fail safe state), SIL 3 contacts at terminals 13-15 and 14-16 are opened,
the load is de-energized. Presence of diagnostic circuit power supply, status of input / output channel (energized or de-energized), as well as any type of fault condition (line and load
short/open circuit, relay coil short circuit, etc.) are displayed by related signalling LEDs: green power supply, yellow for status channel and red for fault.
Installation
D5293 series is a relay output module housed in a plastic enclosure suitable for installation on EN/IEC60715 TH 35 DIN-Rail, with or without Power Bus or on customized Termination
Board. D5293 series can be mounted with any orientation over the entire ambient temperature range.
Electrical connection 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). Connect only one individual conductor per each clamping point, use conductors up to 2.5 mm²
(13 AWG) and a torque value of 0.5-0.6 Nm. 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 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 “9” and negative at terminal “10”.
Connect positive input at terminal “1” and negative input at “2”.
Connect Fault output 1 (30 V, 500mA) at terminals “3” and “4” and Fault output 2 (250 V, 3A) at terminals “11” and “12”.
Connect A- Modbus RS845 for diagnostic at terminal “5” and B+ at terminal “6”.
Connect positive output Normally Energized load at terminal “13” and negative at terminal “14”.
Connect positive Load Power DC/AC at terminal “15” and negative at terminal “16”.
Installation and wiring must be in accordance to the relevant national or international installation standards (e.g. IEC/EN60079-14 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.
Connect 1+1 SPST relay contacts checking the load rating to be within the contact maximum rating 5 A 250 Vac 1250 VA, 5 A 250 Vdc 140 W (resistive load). To prevent relay
contacts from damaging, connect an external protection (fuse or similar), chosen according to the relay breaking capacity diagram on data sheet. The enclosure provides,
according to EN60529, an IP20 minimum degree of protection (or similar to NEMA Standard 250 type 1). The equipment shall only be used in an area of at least pollution degree 2, as
defined in IEC 60664-1. When installed in EU Zone 2, the unit shall be installed in an enclosure that provides a minimum ingress protection of IP54 in accordance with IEC 60079-0. The
enclosure must have a door or cover accessible only by the use of a tool. The end user is responsible to ensure that the operating temperature of the module is not exceeded in the end
use application. 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 D5293 series 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. D5293
series must be connected to SELV or PELV supplies. All circuits connected to D5293 series must comply with the overvoltage category II (or better) according to EN/IEC60664-1.
Warning: de-energize main power source (turn off power supply voltage) and disconnect plug-in terminal blocks before opening the enclosure to avoid electrical shock
when connected to live hazardous potential.
D5293 series is an electrical apparatus installed into EN/IEC60715 TH 35 DIN-Rail located in Safe Area or Zone 2, Group IIC, Temperature Classification T4, Hazardous Area within the
specified operating temperature limits Tamb - 40 to +70 °C. D5293 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. 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 suitability for Zone 2. Warning: de-energize main power source (turn off power
supply voltage) and disconnect plug-in terminal blocks before opening the enclosure to avoid electrical shock when connected to live hazardous potential. 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.
Start-up
Before powering the unit check that all wires are properly connected, particularly supply conductors and their polarity, input and output wires. Check conductors for exposed wires that
could touch each other causing dangerous unwanted shorts. Turn on power for diagnostic circuit, the “power on” green led must be lit. Enabling input, the channel status yellow led must
be lit and load circuit must be energized because 1+1 SPST relay output contacts are closed. Instead, disabling input, the channel status yellow led must be turned off and load circuit
must be de-energized because 1+1 SPST relay output contacts are open.
For configuration of T-proof diagnostic circuits testing, some DIP Switches are located on component side of pcb.
These switches allow the T-proof diagnostic circuit test (SW1 dip-switch: 2 or 3 set “ON” and see “Testing procedure at T-proof for diagnostic application” on ISM0441 Safety Manual).
WARNING: after T-proof test, dip-switch 2-3 must be set
to “OFF” position for normal operation.
