DMM-xx modules of remote I/O with MODBUS protocol

The MODBUS protocol, along with AMiT’s control systems, is suitable for use in situations requiring communication with the equipment of other companies. If an AMiT-produced control system needs to be extended with more inputs and outputs, we recommend using DM-xx input/output modules communicating via the ARION network.

Modules of the DMM-xx series were completely replaced by modules of the AMRIO series.
