Frequently Asked Questions

What socket does the CR-P024DC1 plug into?
The CR-P024DC1 is designed to plug into ABB CR-M series sockets, which are sold separately and provide screw or spring-clamp field wiring connections.

What does 1C/O mean?
1C/O stands for one changeover contact, meaning the relay has one common, one normally open (NO), and one normally closed (NC) contact — giving flexible switching options in a single unit.

Is the CR-P024DC1 suitable for 24VDC control circuits from a PLC output?
Yes. The 24VDC coil rating matches standard PLC 24VDC output supply voltages, making the CR-P024DC1 a direct-fit interface relay for PLC-driven control applications.
