AC500 - S500 I/O modules
We believe expanding or adding field devices should be quite simple. Therefore we develop multifunctional and software configurable I/O modules and provide numerous basic I/O modules with different channels, signal voltage and fieldbus connections.

You can choose and combine your needed type of connection:

Central, using local I/O bus of CPU module.
Up to ten I/O modules can be connected to the CPU.
Decentralized periphery via fieldbus between CPU module and remote I/O modules.
For each fieldbus slave, up to ten I/O modules can be connected.
Multifunctional approach: some modules cover a broad range of requirements, e.g. AI531 with 8 types of different signals in one module.
