750-652 Serial interface RS-232 C/RS-485, light grey

The serial interface terminal allows devices with RS-485, RS-422 and RS-232 interfaces (optional) to be connected to the WAGO-I/O-SYSTEM 750. This can be used to create gateways from the fieldbuses supported by the WAGO-I/O-SYSTEM 750 to a serial interface. The bus terminal does not support higher protocol layers. The communication is completely transparent to the corresponding fieldbus master. This ensures a wide range of applications for the serial interface terminal. Any communication protocols that may be required can be flexibly programmed into the fieldbus master.

The 2560-byte receive buffer size allows the bus terminal to be used, even at high transmission rates. At low data transmission rates, the receive data can be evaluated in tasks with low priority without any loss of data.

The 512-byte send buffer allows larger contiguous data to be transmitted.

The terminal can be freely configured via WAGO-I/O-CHECK or GSD files and a flexible choice of baud rate and the data width enables optimum adaptation to the respective application.
