What this relay is and the coil rating that decides the fit
The ABB CR-M024DC4 is a general-purpose industrial relay with a 24 VDC rated control supply voltage — the coil rating that determines whether it pulls in reliably on your control circuit. The 24 VDC coil matches standard PLC digital output cards and 24 VDC control buses common in panel builds, so the relay energizes directly from a DC output module without an interposing converter.
The CR-M024DC4 carries a current lifecycle stage, meaning ABB still lists it as an active catalog number.
