- 5 A SIL 3 Relay Output Module
G.M. International ISM0152-8
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) short circuit fault detection: it allows DCS/PLC to detect short circuit fault of module;
4) T-proof relay testing.

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.
