750 XTR Series – I/O System RS-232/485 Serial Interface; Extreme

Item no. 750-652/040-000
RS-232/485 Serial Interface; Extreme


This serial interface module connects RS-485, RS-422 or RS-232 interface devices to the WAGO-I/O-SYSTEM 750. It also provides gateways between the serial interface and the fieldbus systems supported by the WAGO-I/O-SYSTEM 750. No higher protocol level is required by the module. Communication is completely transparent to the fieldbus master, which provides a wide range of applications for the serial interface module. If required, communication protocols can be configured via fieldbus master.

The 2560-byte input buffer provides for high data baud rates. At lower baud rates, the data received in lower priority tasks is evaluated without data loss.

The 512-byte output buffer provides fast transmission of larger data strings.

The module can be configured via WAGO-I/O-CHECK or GSD files. Flexible baud rate and data width selection provides perfect adaptation to the respective application

The module is ideally suited for operation in harsh environmental conditions:
- strongly extended temperature range
- higher dielectric strength and EMC resistance
- higher vibration and shock resistance
