WAGO 750-652

WAGO 750-652 – Serial Interface Module (RS-232 / RS-422 / RS-485)

Overview

The WAGO 750-652 is a serial interface module that connects devices using RS-232, RS-422, or RS-485 to the WAGO I/O System 750. It works as a transparent gateway between field devices and controllers, offering large input/output buffers and flexible configuration of baud rate, parity, data bits, and stop bits to meet diverse application needs.

Key Features

• Supports RS-232, RS-422, and RS-485

• Configurable baud rate: 300 … 115,200 Baud

• Large buffers: 2560-byte input / 512-byte output

• Flow control for RS-232: XON/XOFF or RTS/CTS

• Transparent data transfer between serial device and fieldbus/controller

• LED indicators for operation, communication, and diagnostics

• Compact 12 mm module width, IP20 protection
