D5091
- 5 A SIL 3 Relay Output Module for ND Load with ND or NE Relay condition
G.M. International ISM0110-12
Start-up
Before powering the inputs of unit check that all wires are properly connected, also verifying their polarity. Check conductors for exposed wires that could touch each other causing
dangerous unwanted shorts. Enabling input, the corresponding “RELAY STATUS” yellow led must be lit and load circuit must be according to the connection required.
Indeed, disabling each input, the corresponding “RELAY STATUS” yellow led must be turned off and load circuit must change the status.
Configuration
An eight position DIP Switch is located on component side of pcb in order to set four mutually exclusive configurations:
1) line input monitoring, to allow DCS/PLC line input monitoring function (driving line pulse testing);
2) low voltage input monitoring (UVLO—under voltage lock out): module reflects a high impedance state to the control unit when the driving voltage is below the specified threshold;
3) T-proof relay testing.
WARNING:
dip-switch 2-4-6
must be set to “OFF” position
for any configuration.

Please, see next page for testing procedure at T-proof.
WARNING:
after T-proof test, dip-switch 1-3-5 must be set to “OFF” position for normal operation.
To prevent relay contacts from damaging, connect an external protection (fuse or similar), chosen according to the relay breaking capacity diagram from installation
instructions.
The enclosure provides, according to EN60529, an IP20 minimum degree of protection (or similar to NEMA Standard 250 type 1). The unit shall be installed in an area of no more than
pollution degree 2 according to EN/IEC60664
-
1. When installed in EU Zone 2, the unit shall be mounted in a certified Ex enclosure that provides a degree of protection not less than IP54
in accordance with EN/IEC60079-15. When installed in a Class I, Division 2 Hazardous Location, the unit shall be mounted in a supplemental enclosure that provides a degree of
protection not less than IP54. 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 D5091 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.
All circuits connected to D5091 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.
