METZ BMT-F-DO4 BACnet MS/TP Field Device with 4 Relay Outputs, 4 Universal Inputs, 2 Analog Outputs, RS485, DIN Rail Mount, 24V AC/DC 110886132170

Equipped with four relay outputs rated up to 3A at 250V AC, the METZ BMT-F-DO4 delivers robust switching for HVAC and building automation. This BACnet MS/TP field device combines four universal inputs, two 0-10V analog outputs, and RS485 communication in a compact 6 TE DIN rail module.

Overview

The METZ BMT-F-DO4 is a versatile BACnet MS/TP field device designed for room automation and building management systems. It features 4 relay outputs for direct control of actuators, valves, or fans, along with 4 universal inputs configurable for NTC, Pt1000, 0-10V, or digital contact signals. Two analog outputs provide 0-10V DC control for modulating devices. Communication via RS485 supports baud rates from 9600 to 76800 bps, with DIP switches for easy addressing and baud rate selection. The device operates on 24V AC/DC and mounts on a standard DIN rail, occupying only 6 TE (modules).
