DM-xx modules of remote I/O with ARION protocol

The extension modules of the DM-xx series with ARION protocol have their own ‘intelligence’ – they are able to detect when communication is cut off and set the output signals to a pre-defined setting in such cases. The I/O modules on offer can be single-type (one type of I/O signal) or combined.

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

An overview of the I/O extension modules with ARION protocol

*) 0 to 5 V / 0 to 10 V / 0 to 20 mA / Ni1000 / Pt1000 / contact / digital input 24 V DC

The same types of extension inputs/outputs are produced for the DMM-xx series of modules with MODBUS RTU protocol.
