The WAGO 753-650 RS-232 Serial Interface connects devices with RS-232-C ports directly to WAGO I/O systems. It supports full duplex communication and works independently of the higher-level fieldbus system, making it ideal for flexible data exchange.
This module follows TIA/EIA-F, CCITT V.28, and DIN 66259-1 standards. It operates at baud rates up to 19200 and uses 8 data bits, 1 stop bit, and no parity. The interface ensures high interference immunity through electrical isolation and connects its shield directly to the DIN rail for added protection.
Engineers use the 753-650 to integrate barcode scanners, printers, and other serial devices into automation systems. It simplifies communication between field devices and controllers, especially in setups that require reliable, point-to-point data transfer.
The module installs easily into WAGO’s 753 Series I/O system and runs on a 5 V supply. Its compact design and robust performance make it a dependable choice for industrial environments where serial communication is still essential.
