The DTFPM-ZJ fire protection equipment power monitoring relay box independently developed and produced by our company can not only increase the communication distance of the system, but also provide power for the connected field sensors (current and current sensors) to solve the communication caused by the distance too far. Attenuation of signal and power output. The relay box transmits the power information of the connected field modules and relays to the monitor (host) through the communication bus. The branch box has no communication relay function, only the sensor power supply function is added
■The repeater adopts wall-mounted installation;
■Standby Power supply: When the main Power supply has low voltage or power failure, maintain the repeater working time ≥ 8h;
■24-hour working system, Modbus-RTUcommunicationprotocol, RS485 half-duplex bus mode
■Monitoring capacity: ≤32 points
■Shell protection level: IP51
■ Wall-mounted installation, small size, small footprint;
■Easy installation, simple wiring, convenient construction and simple debugging;
■Increase signal distance and strong power load capacity;
■Main Power supply: AC220V 50Hz (varies within the range of Allow85%~110%), rated output power: 180W;
