MR-AO-1 analogue output module

MAX-MR-AO-1, 5908312595236

A module with 4 analogue voltage outputs (0–10 V) featuring Modbus RTU communication.
4 independent 0–10 V voltage outputs.
Output value memory.
Communication interface: RS-485.

MR-AO-1 4-output analogue module, 0–10 V, Modbus RTU

Why choose the MR-AO-1?

The MR-AO-1 extends the system with four analogue voltage outputs controlled via RS-485 in accordance with the Modbus RTU protocol. The module is designed to expand the analogue outputs of PLCs or other compatible devices.

What does this mean in practice?

  • The module features 4 independent analogue voltage outputs.
  • The range of each output is 0–10 V.
  • The output values are set via Modbus RTU communication.
  • The module has a memory for output values.
  • The communication interface is RS-485.
  • LEDs indicate power supply and data transmission.

Reset of communication settings
A DIP switch is located beneath the module’s front panel.
Details on resetting are available in the manual.

MB Config
The programme allows you to test-read values and configure the module’s communication and configuration parameters.



Communication between the module and a PC via theCN-USB-485 USB converter

The programme is free of charge.
