The BMS-1WIRE allows users to leverage protocols to integrate RLE’s 1-wire temperature and temperature/humidity sensors into any building management system (BMS) or alarm monitoring system.
The BMS-1WIRE Includes:
- Supports up to 8 of RLE’s 1-wire sensors.
- Robust protocols for communication with any Modbus RTU or BACnet MS/TP system.
- No user interface or separate software required – integrates directly with existing BMS and alarm monitoring systems.
- Enclosure mounts in a panel, on a DIN rail, or on a wall.
