This is a question we received this week about current sensors.
Can you use a current switch contact to energize a contactor coil if I have 24 volt transformer power going through the contact to power a contactor coil? I am not sure how the switch works if the switch needs its own power or just closes a contact when current is sensed? I have to interlock 3 exhaust fans and a damper and this would make my life easier.
RibRelays.com can make your life easier – our RIB current sensors will work perfectly for your application. A RIB current sensor will close its contact when current is sensed. You do not need additional power for the RIB to function.
We currently have two styles of current sensors that you can choose for this application such as the RIBXKTF (Enlosed Solid-Core Sensor) or RIBXGTA (Enclosed Split-Core Sensor). You will select the current sensor you need based on the amperage draw being applied to the sensor. BHUW3TCXGXZS
