Collecting Device of the Discrete Data
USDM-01


USDM-01 - collecting device of the discrete data
USDM-01

USDM-01 is the collecting device of the discrete dataand control with the data transmission under the MODBUS RTU Protocol.

The device is intended for the transmission of the discrete signals condition of the automation object to the monitoring (control) system and also for the implementation of the system commands via the built-in relays.
