MB-RTU-01/230 is a wireless Modbus-RTU master that connects standard RS-485 Modbus RTU devices to an IQ Home IQRF-DPA network. It reduces the need for long RS-485 control cables between distributed devices and the gateway or control system.

Key features

  • Wireless Modbus RTU connectivity over IQRF-DPA
  • Centralised collection of Modbus RTU data
  • Centralised control of Modbus RTU devices
  • 230 V AC supply version
  • DIN-rail mounting with internal PCB antenna
  • LED indication for power, RF communication and Modbus communication
  • Operating temperature: -30 to +70 °C; IP20 enclosure

Typical applications

  • Reading Modbus RTU sensors and meters
  • Controlling Modbus RTU actuators
  • Connecting Modbus devices to a PLC or gateway without separate RS-485 control wiring
  • Distributed energy and utility metering

Power-meter application

Connect a compatible Modbus smart meter to the MB-RTU-01/230 and collect its measurements through the wireless IQRF-DPA network. This allows electrical consumption to be monitored together with other connected devices.

Package contains: MB-RTU-01/230 Modbus-RTU master.
