Overview
The ABB CR-P120AC2 pluggable interface relay (part number 1SVR405601R2000) is a compact PCB-mount relay from ABB’s CR-P family, engineered for reliable switching in industrial control circuits. This relay provides DPDT (Double Pole Double Throw / 2 c/o) contact configuration with a 120VAC control coil voltage, making it suitable for standard voltage environments in manufacturing, HVAC, and process automation systems.
Key Features
- 120V AC rated control supply voltage (coil)
- 2 c/o (DPDT) contact configuration for dual-circuit switching
- Contact rating: 250V / 8A per pole
- Pluggable PCB mount design—easy terminal insertion and replacement
- Silver-nickel (AgNi) contacts for reliable electrical performance
- Compact footprint: 12.7mm wide × 15.7mm high × 29mm deep
- Response time (closing): 7ms
- High mechanical durability: 30,000,000 operations at no load
- Electrical durability: 100,000 operations with load (600 ops/hr)
Technical Specifications
This relay meets industrial standards and is suitable for panel-mount and control cabinet applications. Standard sockets, logic sockets, and pluggable function modules are available as accessories for integration into larger control systems. The CR-P design allows straightforward hot-swapping, reducing downtime during maintenance.
Typical Applications
- Industrial machine control and motor switching
- HVAC and building automation systems
- Process control and instrumentation
- Alarm and interlock circuits
- General-purpose relay banks and logic control
Compatibility & Replacements
The CR-P120AC2 is part of ABB’s established CR-P pluggable relay family. While direct pin-compatible replacements exist within the CR-P series (different voltage and contact ratings), always verify coil voltage, contact configuration, and current rating for your specific application. This relay is widely available from authorized distributors including Newark Electronics, Gerrie, and iAutomation. Original packaging and 10-unit cartons are standard stock items for quick replenishment in production environments.
