These relay solutions are widely used in PLC and DCS systems, automation panels, oil & gas facilities, chemical plants, energy infrastructure and industrial machinery.

Electromechanical Relay Modules – Klippon® Relay

Operating principle and technical advantages

Electromechanical relays from the Klippon® Relay series use mechanical contacts to switch electrical loads, providing galvanic isolation between the control circuit and the load circuit.

• High load switching capability for AC and DC applications

• Long mechanical service life for industrial environments

• Safe isolation between PLC outputs and field devices

• Easy maintenance and replacement thanks to modular design

Klippon® relay modules are typically equipped with status LEDs, flyback diodes or RC protection circuits, ensuring reliable operation and protecting PLC outputs from voltage peaks.

Solid-State Relays (SSR) – Klippon® Relay

Semiconductor technology – No mechanical contacts

Weidmüller solid-state relays use semiconductor switching technology instead of mechanical contacts, making them ideal for applications that require fast switching, high switching frequency and spark-free operation.

• No mechanical wear – extended service life

• Fast switching speeds for precise control tasks

• Excellent vibration and shock resistance

• Silent operation with no mechanical noise

Klippon® solid-state relays are especially suitable for hazardous areas, oil & gas installations, chemical processing plants and highly automated systems.

Advanced connection technologies

Klippon® Relay modules are available with Weidmüller’s proven connection technologies:

• PUSH IN – tool-free wiring, vibration-proof and fast installation

• Screw connection – traditional, robust and universally accepted

• Tension clamp – constant contact pressure, excellent vibration resistance

These technologies significantly reduce wiring time, minimize installation errors and ensure long-term electrical reliability.

International safety standards and approvals
