ZMB Wireless Modbus Bridge
Bridge Modbus RTU devices to your wireless IoT network. Connect third-party meters and sensors without running data cables.
Modbus RTU to ZigBee
The ZMB acts as a transparent bridge between Modbus RTU devices and the EpiSensor ZigBee mesh network. Connect any Modbus-compatible meter, sensor, or controller to your wireless IoT infrastructure without proprietary converters or custom development.
Industry-Standard RS-485 Connection
The ZMB features an RS-485 serial interface supporting standard Modbus RTU communication. Connect to a wide range of third-party energy meters, power analysers, environmental sensors, and industrial controllers using the most widely adopted serial protocol in building and industrial automation.
Read Any Modbus Register
Configure the ZMB to read specific Modbus registers from connected devices, mapping data points to your IoT platform. Support for multiple Modbus devices on a single RS-485 bus means one ZMB can serve an entire panel of meters.
