Control Relays
Control Relays
(OP)
Hi anyone who is reading this,
I was wondering what the difference is between a "Control Relay" and a conventional relay is?
As is, I believe the control relay requires a remote signal to turn it on/off and the conventional relay only requires power applied to the coil.
Cheers,
Thank you

RE: Control Relays
1. IEEE Std 100 "Dictionary"
Control Relay:
Is an auxiliary relay whose function is to initiate or permit the next desired operation in a control sequence.
Conventional Relay:
It is not defined in Reference 1.
RE: Control Relays
If you have electrical experince, you may also say that the low voltage circuit is control, while the high voltage side is drive.
RE: Control Relays
Understand that there are significant differences in machine-tool control relays and vending-machine-grade [often having push-on connections or socket-based] devices. Specification depends on value of associated equipment, and cost of process interruption for malfunction(s). Machine-tool versions typically have replaceable contact cartridges and coils for varying switching/voltage/current levels. Consumer-appliance-type devices are (hopefully!) trashed if any part of the relay has failed or is intermittent.
