Intended Purpose

The digital input/output module DC561 can be connected to the following devices via the I/O bus connector:

• S500 bus modules (e. g. CI501-PNIO, CI541-DP, CI581-CN)
• AC500 CPUs (PM5xx)
• other AC500 I/O modules

Note

The I/O module must not be used as a decentralized communication interface module with DC505-FBP and CI590-CS31-HA bus modules.

The module contains 16 digital channels in 1 group, each channel can be used as a digital 24 VDC input or 24 VDC output.

The inputs/outputs are group-wise electrically isolated from each other.

All other circuitry of the module is electrically isolated from the inputs/outputs.
