Wago 750-650 I-System Serial Interface Module

The WAGO 750-650 I-System Serial Interface Module enables RS-232C serial data communication within industrial automation and distributed I/O setups, linking PLC controllers with HMIs and RS-232-compatible field devices. Designed for DIN rail mounting with cage clamp wiring, it supports point-to-point serial communication across the WAGO I/O System 750 family and provides integrated LED diagnostics for quick status checks, with modular expansion to accommodate growing systems; industrial environment rated: Yes. Commonly deployed in packaging machinery, conveyor lines, process control skids, OEM automation equipment, and industrial control panels, the module enables reliable serial data exchange with barcode scanners, printers, serial sensors, weighing systems, and legacy devices. Part of the WAGO I/O-SYSTEM 750, it features an industrial thermoplastic housing and is compatible with 750 Series I/O Systems, using RS-232C and cage clamp wiring to connect devices on a DIN rail, with common replacements including 750-652, 750-653, and 750-657.
