METZ CONNECT BMT-DI10 BACnet MS/TP Digital Input Module 10 Inputs

The METZ CONNECT BMT-DI10 is a high-performance BACnet MS/TP digital input module designed for building automation and control systems. With 10 digital inputs, it reliably monitors dry contacts or 24 V AC/DC voltage signals, making it ideal for integrating sensors, switches, and status indicators into a BACnet network. The module communicates via RS485 with selectable baud rates from 9600 to 76800 bps and features DIP switch addressing for up to 127 devices. Its compact DIN rail housing (IP20) ensures easy installation in control cabinets.
