AC500-eCo/S500-eCo system structuredl-permalink__symbolPermalink

AC500-eCo/S500-eCo series is compatible with AC500/S500.

The compact AC500-eCo processor module can be used for small applications with the integrated I/O channels.

The functionality of the processor modules can be extended with option boards, e.g., for additional I/O channels.

For larger applications, I/O modules can be connected centralized or decentralized.

Terminal blocks in different variants available

Centralized I/O extension

Processor modules with an I/O bus interface on the right side can be expanded by up to 10 I/O modules to increase the number of the I/O channels.

Decentralized I/O extension

Up to 10 I/O modules can be connected remotely with the onboard Ethernet interface. Usually, a Modbus/TCP communication interface module or a processor module is used for the decentralized I/O extension.
