5.Other Function
5.1 Dry node function
Working principle: this dry node can control the switch of diesel generator to charge the
battery.
①
Under normal conditions, in this terminal, NC-N point is closed and NO-N point is opened;
②
when the battery voltage reaches the low-voltage disconnection voltage point, the coil of the
relay is energized and NO-N point is closed and NC-N point opened. At this time, NO-N point can
drive resistive loads 125VAC/1A, 230VAC/1A and 30VDC/1A.
5.2 RS485 communication function
There are two communication ports RS485-1 and RS485-2 and also two functions:
①
RS485 communication with lithium battery BMS can be conducted directly through this
port RS485-2 (need to be customized);
②
RS485-1 is connected to the selected RS485 to WiFi /GPRS communication module
independently developed by our company After the selected module is equipped, the reverse control all-in-
one machine of our company can be connected through mobile APP, and the operating parameters and status
of the reverse control all-in-one machine can be checked through the mobile APP.
③
Such as shown in the figure: pin 1 is 5V power supply; pin 2 is GND, pin 7 is RS485-A and pin 8 is RS485-B.
5.3 USB communication function
This port is a USB communication port, which can be used for USB communication with the
selected upper computer software of our company (Need to apply for). To use this port, the
corresponding “USB to serial port chip CH340T driver” should be installed in the computer.
