Intended Purpose

The PROFIBUS DP Bus Module CI541-DP is used as decentralized I/O module in PROFIBUS DP networks. Depending on the used Terminal Unit the network connection is performed either via 9-pole female D-SUB connector or via 10 terminals (screw-type or spring terminals) which are integrated in the Terminal Unit. The Bus Module contains 22 I/O channels with the following properties:

  • 4 analog inputs (2.0…2.3)
  • 2 analog outputs (2.5…2.6)
  • 8 digital inputs 24 VDC in 1 group (3.0…3.7)
  • 8 digital outputs 24 VDC in 1 group (4.0…4.7)

The inputs/outputs are electrically isolated from the PROFIBUS DP network. There is no potential separation between the channels. The configuration of the analog inputs/outputs 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.
