AC 800M is a hardware platform comprising individual hardware units, which can be configured and programmed to perform multiple functions. Once configured and programmed, the AC 800M effectively becomes the AC 800M or AC 800M HI controller.

The AC 800M Controller provides a cost-effective, low-maintenance solution for applications ranging from small Programmable Logic Controller (PLC) to advanced Distributed Control Systems (DCS) control applications and combined DCS, and High Integrity systems control applications.
