Material Composition

Housing: UL 94 V-0 flame-retardant polyamide. PCB: FR-4 glass epoxy. Connectors: gold-plated copper alloy. I/O terminals: cage clamp copper alloy.

Structural Characteristics

It features compact WAGO 750 series form factor, front panel status LEDs, RJ45 Ethernet port, side I/O bus connector, cage clamp power terminals, and DIN rail mounting base.

Working Principle

It acts as a gateway between the Ethernet network and the WAGO I/O system bus. It converts network packets to I/O bus commands and vice versa, exchanging data between the host controller and distributed I/O modules.

Installation Requirements

Mount on standard 35mm DIN rail. Connect 24V DC power supply. Plug in Ethernet network cable. Connect WAGO I/O modules to the side bus. Configure via web interface or configuration software.

Usage Notes

Assign unique IP address for each coupler. Check status LEDs for fault diagnosis. Use only WAGO-approved I/O modules. Follow ESD handling procedures.
