Voltage and Current Controlled Relay Modules
We have some 2-20V and 50-500V Voltage Controlled Relays and 50 - 500mA Current Controlled Relays available that have a standard 11-pin base (for use in monitoring applications).
Also available are some replacement units for Landis & Gyr SEM35.1 Compressor Monitors. They ensure the compressor heater circuit is drawing current and give an alarm signal if not. A few engineers have asked if we could make these as apparently they are no longer in manufacture?
