Phoenix Contact RIF-1-RSC

This time relay RIF-1-RSC-LDP-24DC/1X21 2903358 from Phoenix Contact is the cost-effective alternative to a PLC with easy configuration and fast wiring.

Features and Benefits

  • Pre-assembled relay module

  • Screw connection

  • Consists of: relay base, power contact relay, plug-in display/interference suppression module, and retaining bracket

  • Contact type: 1 changeover contact

  • Time-saving potential distribution, thanks to plug-in bridges

  • Protection against operating errors due to manual operation that is lockable via screwdriver

  • Quick and error-free connection to the controller via system cabling


When working on the products and the system, you must always keep the operating instructions and other items of product documentation to hand and follow them strictly.

Demands on the power supply

Only use power supply units that ensure safe isolation between the primary and secondary circuits according to EN 50178.


You can use the same electromechanical relay module design for both AC and DC switching module.

  • Electrical isolation

  • Voltage adjustment of frequently varying voltage levels

  • Power amplification

  • Signal multiplication in the case of relay modules with multiple contacts (e.g., for signal confirmations)
