General Description: The single channel DIN-Rail Loop Powered Digital Output Isolator, D1048S, is suitable for driving solenoid valves, visual or audible alarms to alert a plant operator,
or other process control devices in Hazardous Area from a driving signal in Safe Area. It can also be used as a controllable supply to power measuring or process control equipment.
Its use is allowed in applications requiring up to SIL 3 level (according to IEC 61508) in safety related systems for high risk industries.
The Safety PLC or DCS driving signal powers the field device through the D1048S, which provides isolation and is capable of monitoring the conditions of the line.
Short and open circuit diagnostic monitoring, dip-switch selectable and active when input power is present, provides LED indication and NC transistor output signaling.
When fault is detected output is de-energized until normal condition is restored. Line short and open output circuit fault detection is also reflected on the PLC / DCS input circuit
providing less than 10 mA consumption.
An override input, dip-switch selectable, is provided to permit a safety system to override the control signal. When enabled, a low input voltage always de-energizes the field device
regardless of the input signal.
Three basic output circuits are selectable, with different safety parameters, to interface the majority of devices on the market. The selection among the three output characteristics
is obtained by connecting the field device to a different terminal block.

Warning
The single channel DIN-Rail Loop Powered Digital Output Isolator, D1048S, is suitable for driving solenoid valves, visual or audible alarms to alert a plant operator, or
other process control devices in Hazardous Area from a driving signal in Safe Area. It can also be used as a controllable supply to power measuring or process control equipment.
Its use is allowed in applications requiring up to SIL 3 level (according to IEC 61508) in safety related systems for high risk industries.
The Safety PLC or DCS driving signal powers the field device through the D1048S, which provides isolation and is capable of monitoring the conditions of the line.
Short and open circuit diagnostic monitoring, dip-switch selectable and active when input power is present, provides LED indication and NC transistor output signaling.
When fault is detected output is de-energized until normal condition is restored. Line short and open output circuit fault detection is also reflected on the PLC / DCS input circuit
providing less than 10 mA consumption.
An override input, dip-switch selectable, is provided to permit a safety system to override the control signal. When enabled, a low input voltage always de-energizes the field device
regardless of the input signal.
Three basic output circuits are selectable, with different safety parameters, to interface the majority of devices on the market. The selection among the three output characteristics
is obtained by connecting the field device to a different terminal block.
Presence of output, as well as integrity or fault condition of device and connecting line are displayed by signaling LEDs (yellow for status, red for fault).

Power Dissipation of D1048 Isolators
Section “Technical Data” of D1048 isolator specifies the current consumption (maximum current from the nominal power supply, typical 24 Vdc, in normal operation);
this data serves to dimension the current rating of the power supply unit. Section “Technical Data” indicates also the maximum power consumption (maximum power required from the
power supply in the worst (abnormal) operating conditions like for example supply voltage at 30 Vdc, short circuit on the outputs terminals.
The power dissipated Pd inside the enclosure is: Pd = Current Consumption (A) * Supply Voltage (V) - Power Dissipated into the output load
Isolators are not running at the maximum current all at the same time, the average power consumption of a multitude of isolators can be considered to be only 70 % of the value obtained
from the section “Technical Data”. Considering the power dissipated by the load (typical 1/3 of input power), and the 70 % above discussed, the power effectively dissipated internally
by the isolators can therefore become ½ of the actual power delivered by the power supply.
The following tables give advises for DIN-Rail orientation (vertical or horizontal) of barriers mounting, or installation on custom board assembly.
A) Cabinet with Natural Ventilation
Maximum recommended ambient temperature in °C depending on installation method:
Installation in Cabinet
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.
Activate the control signal, the “status” yellow led must be lit, fault led must be in accordance with condition of the corresponding output line.
If possible change the status of driving signal and connection line one at time checking the corresponding status and fault leds condition as well as output to be correct.
Installation
D1048 is a digital output isolator housed in a plastic enclosure suitable for installation on T35 DIN Rail according to EN50022.
D1048 unit can be mounted with any orientation over the entire ambient temperature range, see section “Installation in Cabinet” and "Installation of Electronic Equipments in Cabinet"
Instruction Manual D1000 series for detailed instructions.
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 or Division 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 and configuration DIP switches.
Identify the function and location of each connection terminal using the wiring diagram on the corresponding section, as an example:
Connect control input signal positive at terminal “5” and negative at terminal “6”.
Connect fault open collector transistor output positive at terminal “1” and negative at terminal “2”.
Connect override input at terminal “7” positive and at terminal “8” negative.
Connect positive output at terminal “13” and negative output at “16” using “Out A” diagram or positive output at terminal “14” and negative at terminal “16” using “Out B” diagram or
positive output at terminal “15” and negative at “16” using “Out C” diagram.
NOTE: use only one output at a time, Out A or Out B or Out C not contemporary.
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), BS 5345 Pt4, VDE 165,
ANSI/ISA RP12.06.01 Installation of Intrinsically Safe System for Hazardous (Classified) Locations, National Electrical Code NEC ANSI/NFPA 70 Section 504 and 505,
Canadian Electrical Code CEC), make sure that conductors are well isolated from each other and do not produce any unintentional connection.
Connect SPST output transistors checking the load rating to be within the maximum rating (100 mA, 35 Vdc resistive load).
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 D1048 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.
