Analog voltage output MR-AO-1

Analog voltage output MR-AO-1

MAX-MR-AO-1, 5908312595236

Product description

Extension module with output MODBUS RTU.
MR-AO-1 module serves as an external device which expanding analog voltage outputs of PLCs or other devices in which data exchange is via the RS- 485 according to the MODBUS RTU protocol.

The module has 4 analog voltage outputs 0-10V. The values of the outputs volages can be set or read via RS-485, using MODBUS RTU protocol. The module has the function of recording the output voltage non-volatile memory in the local area. Each time you power up the module output value will be restored to the saved state.
Setting communication parameters is realized through the RS-485 port using MODBUS RTU communication protocol.
Switching ON the power is indicated by lighting the green LED U. Laws correct exchange of data between the module and the second device is indicated by a 
yellow LED lighting Tx.
