CR-P024DC2 ABB 24V DC Pluggable PCB Interface Relay
The CR-P024DC2 ABB (ABB Order Code: 1SVR405601R1000) is a high-performance miniature plug-in interface relay designed for signal galvanic isolation, amplification, and matching between electronic controllers (such as PLCs or SCADA systems) and high-power field actuators. Operating on a 24V DC control supply, the CR-P024DC2 ABB provides 2 changeover (2 c/o / DPDT) contacts rated for switching currents up to 8A at 250V AC.
Engineered for high reliability in compact electrical cabinets, the CR-P024DC2 ABB features cadmium-free contact material and IP67-rated wash-tight housing protection. Designed for direct insertion into ABB CR-P sockets (screw or logical spring terminals) or soldering onto PCB circuit boards, it provides complete electrical separation between low-voltage control logic and high-power load circuits.
Key Features of the CR-P024DC2 ABB
-
2 Changeover (DPDT) Contacts: Enables dual-circuit switching or SPDT interlocked control with an 8A continuous current rating per pole.
-
24V DC Low Power Coil: Optimized for direct driving from PLC digital output cards, SCADA I/O modules, and 24V DC industrial power supplies.
