D5290 - 10 A SIL 3 Relay Output Module for NE Load G.M. International ISM0111-8
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 “RELAY STATUS” yellow led must be lit and load circuit must be energized because relay output contacts (Out 1 and Out 2) are closed.
Indeed, disabling input, the “RELAY STATUS” yellow led must be turned off and load circuit must be de-energized because relay output contacts (Out 1 and Out 2) are open.
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.
