Current Sensor Question

RIBXGTA Enclosed Split-Core Sensor

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.

Answer 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

Reason #2 to buy a RIB relay online

My last post talked about how convenient it is to buy a RIB relay online. Reason #2 goes hand in hand with convenience, buying a rib relay online saves you time.

Sometimes shopping online presents you with so many options it is difficult to make a decision about what you need. Not the case when you are purchasing a RIB relay online.

When you need a rib relay, you need a rib relay. Come to Type in the Functional Devices part #. See a picture and read product information. Buy it for a great price. Have your Functional Devices parts shipped directly to you.


You didn’t need to call around to find the part. You didn’t need to drive to pick it up.  You didn’t drive, so you didn’t have to  stop for gas. You didn’t go out, so you didn’t leave your gloves, hat, wallet, [insert what you lose here] anywhere you were along the way – so you didn’t need to spend any time backtracking to find them. And, you didn’t need to make a special stop for a coffee to warm up after being out in the cold winter air.
