Intended Purpose

The Digital Input/Output Module DX531 can be used as a remote expansion module at the following devices:

• S500 Bus Modules (e. g. DC505-FBP, CI592-CS31, CI501-PNIO, CI541-DP, CI581-CN)
• AC500 CPUs (PM5xx)

It contains the following features:

• 8 digital inputs 120/230 V AC in 1 group (2.0 … 2.3 and 3.0 … 3.3)
• 4 digital relay outputs with one switch-over contact each (R0 … R3). All output channels are electrically isolated from each other.

The configuration is performed by software. The modules are supplied with a process voltage of 24 V DC.

The inputs/outputs are electrically isolated from the other electronic circuitry of the module. There is no potential separation between the input channels within the same group.

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