Phoenix Contact PLC-RSC-24DC/21-21 | 24V DC DPDT Relay, 6A
Phoenix Contact PLC-RSC-24DC/21-21 interface relay module. 24V DC coil, DPDT contacts, 6A switching, screw terminals, DIN rail mount.
Product Overview
The Phoenix Contact PLC-RSC-24DC/21-21 is a compact PLC interface relay designed for signal amplification and isolation in control systems. It features a 24V DC coil and DPDT (2-changeover) contacts capable of switching up to 6A. The module consists of a plug-in relay and a screw terminal base, offering a typical input current of 18 mA and built-in LED status indication. It is commonly used to interface between low-power PLC outputs and higher-power loads such as contactors, solenoid valves, and indicators.
