• Cost-effective
• Use the same electromechanical relay module design for both AC and DC switching voltage
• DIN rail mounting
• SPNO and SPDT models available
• Yellow LED operating voltage display
• Free-wheeling diode Damping diode
• Dimensions 94 x 80 x 6.2 mm

Typical Applications:

The PLC relays are used in many different applications not limited to power amplification, electrical isolation or for using for voltage adjustment of frequency varying voltage levels.

Phoenix Contact Interface Relay Module, Screw Terminal, SPDT - PLC-RSC-24DC/21/EX - 2909524

This high-performance relay from Phoenix Contact isolates and switches signals between a controller and field devices. It's safe to use in gaseous environments where explosions might occur. You'll find it used anywhere from medical equipment to chemical plants.
The relay's slim design allows for maximum packing efficiency on your DIN rail. Its classic screw terminals accept a wide range of wire diameters and hold conductors firmly in place without the risk of damage. Thanks to contacts made from silver alloy material, electrical conductivity is reliable and ensures a stable connection. The unit's base has an IP20 (ingress protection) rating, meaning it's protected against large dirt particles and other solid objects that could interfere with its function.
