ZD1B9002 is a smart connector/sensor for voltage monitoring of LV main switchboard , it can measure active energy, reactive energy, power,AC voltage of each phase, AC current of each phase, power factor, frequency, harmonic... It also equipped with RS485 communication(Modbus-RTU protocol).
2. Technical Parameter
ES810E Smart Connector Sensor
RS485, Protocol: Modbus-RTU
3. Function Description
3.1 Electric Measuring Function
Can measure active/reactive energy,power,AC voltage of each phase,AC current of each phase,power factor,frequency,harmonic；
3.2 RS485 Function
Support RS485 communication.
Communicating with server and send data through RS485 Modbus serial port:
*Server will adopt “Readout” function, request data from connector/sensor and obtain RS485 data string when normal status and internet non-fault status.
*The connector sensor upstream to control center server for instananeous alarming, the initiative to report the abnormal when abnormal.
*Adopt four-wire RS485, concentrator needs to provide power supply of 5V/50mA, if remove RS485 then the connector sensor can not work.
3.3 Alarming Function
9 LED status indicators, the left one LED1 is impulse indicator, the right 8 LEDs for status of 8 ways fuses, LED will blink when alarming.
3.4 Switching Capacity Output (S)Function
Max voltage 48V, max current 80mA,
Alarming range: overvoltage,low voltage, over current, overload,THDU,THDI, over frequency, low frequency, low power factor etc.
3.5 Voltage Input Terminals
8 voltage input terminals which support to set the alarming voltage value when issues with fuse, 8 voltage input terminals and the connector sensor shall be same phase voltage and connected from the end of fuse.
3.6 Temp. Measuring Function
Temperature sensing via chip (PS: just for reference of temperature changes,no accuracy info)
