This time relay RIF-1-RSC-LDP-24DC/1X21 2903358 from Phoenix Contact is the cost-effective alternative to a PLC

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.

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)
