ABB CR-P024AC1 Pluggable PCB Interface Relay
The CR-P024AC1 is a compact pluggable interface relay from ABB's CR-P range, suitable for direct mounting on a printed circuit board or use with ABB's relay sockets. Operating on a 24V AC control supply, it provides a 1 c/o (SPDT) output rated at 250V/16A and carries an IP67 degree of protection, making it well suited to harsh or exposed environments in UAE control panel and automation applications.
Key Features
- 1 c/o (SPDT) output contact rated at 250V/16A for direct switching of higher-current loads
- 24V AC rated control supply voltage for compatibility with standard low-voltage control circuits
- IP67 degree of protection offers complete dust ingress protection and resistance to temporary immersion in water
- Compact soldering-pin design suitable for direct PCB mounting or socket-based installation to save panel space
- Genuine ABB quality — rated for operation from -40°C to +70°C

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.
