Intended Purpose

Note

Currently, the CS31 Bus Module DC551-CS31 can only be used together with the AC500 CPUs and dedicated PS501 Control Builder.

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 24 I/O channels with the following properties:

• 8 digital inputs 24 V DC in one group (2.0…2.7)
• 16 digital inputs/outputs in one group (3.0…4.7), of which each can be used
• as an input,
• as a transistor output with short-circuit and overload protection, 0.5 A rated current or
• as a re-readable output (combined input/output) with the technical data of the digital inputs and outputs.

The inputs and output are electrically isolated from the other electronic circuitry of the module.

For usage in extreme ambient conditions (e.g. wider temperature and humidity range), a special XC version of the device is available.
