Intended Purpose

The CANOPEN bus module CI581-CN is used as decentralized I/O module in CANOPEN networks. Depending on the used terminal unit the network connection is performed either via 9-pin female D-sub connector or via 10 terminals (screw 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 CANOPEN network. There is no potential separation between the channels. The configuration of the analog inputs/outputs is performed by software.

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