Product Overview

The CR-M024DC4LD 1SVR405651R3000 is a compact pluggable interface relay from ABB CR‑M series, designed for signal conversion and isolation within PLC, DCS and industrial control panels. It accepts a 24 VDC coil drive signal and switches four independent SPDT contact sets, separating low-power control logic from higher-current field loads such as solenoids, indicators and auxiliary contactors. The integrated LED provides visible energization status, while the built‑in freewheeling diode suppresses voltage spikes from inductive loads to protect upstream controller I/O channels. It mates with dedicated CR‑M socket bases for fast replacement and DIN rail assembly, widely used in power, chemical, machinery and building automation control cabinets.
