The CS31 bus module is used as a decentralized I/O module on CS31 field buses. The bus connection is performed on a RS-485 serial interface, which allows the connection of this module to all existing CS31 buses.
In addition, the CS31 bus module provides 22 I/O channels with the following properties:
-
8 digital inputs, 24 V DC
-
8 configurable digital inputs/outputs 24 V DC, 0.5 A max.
-
4 analog inputs, voltage, current and RTD, resolution 12 bits plus sign
-
2 analog outputs, voltage and current, resolution 12 bits plus sign
The configuration is performed by software.
For usage in extreme ambient conditions (e.g. wider temperature and humidity range), a special XC version of the device is available.
