System Monitoring Relays
SILD and SOD System Monitoring Relays
This range of diagnostic relays are designed to monitor various relay and load conditions. Primarily to flag up an ssr or load failure.
The patented design monitors both the input status (control signal) and the switched output of the relay.
By comparing these values in its microprocessor it will change the status of the diagnostic led's and alarm output in any of these fault conditions:-
- Loss of mains supply
- Load open circuit (e.g. blown heater)
- Failure of its switched output
If any of the conditions occur its alarm will go open circuit signalling a fault to your PLC or control panel.
SOD Range
System monitoring relay in standard hockey puck size.
SILD Range
System monitoring relay mounted on a heatsink with din rail mounting clip.
ESUC Current Monitoring Module
