Lead-frame technology

The lead-frame technology in the PLC-INTERFACE relay series provides the solid foundation for reliably switching, isolating, and amplifying signals: Press-fit components ensure increased vibration resistance. The optimized thermal management extends the service life of electronic components. We realize sustainability with easily separable materials as well as pluggable relays.

VARIOFACE PLC-V8 adapters

The system cabling adapter enables the quick, easy, and error-free connection of relay modules to the controller.

Comprehensive accessories

With color-coded and insulated plug-in bridges, the PLC relay modules can save up to 70% wiring time. The fuse adapter with an overall width of 6.2 mm makes it possible for you to fuse channel-by-channel without taking up additional space on the DIN rail.

PLC logic programmable logic relay system

Switch and control I/O signals with a highly compact and flexible system. You can combine the logic module with the corresponding relay and analog modules as required. The modular structure enables a broad spectrum of application options.

PLC logic – ´programming and configuration

Easy parameter adjustments and flexible monitoring via app with the corresponding Bluetooth adapter. LOGIC+ is the intuitive software for quickly implementing your projects. Integrate the PLC logic via RS-485 (Modbus/RTU) into higher-level control systems.
