ABB CR-M024AC2 Pluggable interface relay 2c/o, A1-A2=24VAC, 250V/12A

ABB CR-M024AC2 Pluggable Interface Relay

The CR-M024AC2 is a pluggable miniature interface relay from ABB's CR-M range, designed to plug into a compatible ABB CR-M socket for snap-on DIN rail mounting. Operating on a 24V AC control supply, it provides a 2 c/o (SPDT) output rated at 250V/12A, allowing multiple circuits to be switched from a single input signal — a common requirement in control panels and automation systems across UAE commercial and industrial facilities.

Key Features

• 2 c/o (SPDT) output contacts rated at 250V/12A for switching multiple circuits from one input
• 24V AC rated control supply voltage for compatibility with standard control circuits
• Integrated test button for manual actuation and easy commissioning without live circuit testing
• Integrated LED provides visual indication of relay coil energization
• Genuine ABB quality — plugs into standard CR-M sockets for fast DIN rail installation

Technical Specifications

Applications

• Signal interfacing between PLCs and higher-power output circuits in control panels
• Switching multiple circuits simultaneously from a single control signal in automation systems
• Relay logic and control wiring in BMS and building automation installations across the UAE
• Interface relay applications in industrial control cabinets and panel builder assemblies

FAQ

• What is a pluggable interface relay used for?
  It electrically isolates a low-power control signal (e.g. from a PLC, BMS, or sensor) from the higher-power circuit it needs to switch, and lets multiple contacts be switched simultaneously from one control signal — commonly used for signal interfacing, contact multiplication, and small load switching in control panels.
• Does this need a separate socket/base to install?
  Yes — pluggable relays like this mount into a compatible DIN-rail or PCB-mount socket (check the Technical Specifications table for the matching socket model) rather than being hard-wired directly, so the relay itself can be swapped without rewiring.
• What does the contact configuration (e.g. 2c/o, 4c/o) mean?
  "c/o" means changeover — each contact set has both normally-open and normally-closed positions. The number (2 or 4) is how many independent changeover contact sets the relay switches simultaneously from one coil signal.
• Can I install this myself?
  Fitting the relay into its socket is straightforward, but wiring the socket into a live control panel should be done by a licensed electrician or qualified panel builder.
