5. Other functions
5.1 Dry node
Working principle: This dry node can control the ON/OFF of the diesel generator to
charge the battery. ① Normally, the terminals are that the NC-N point is closed and
the NO-N point is open; ② When the battery voltage reaches the low voltage
disconnection point, the relay coil is energized, and the terminals turn to that the
NO-N point is closed while NC-N point is open. At this point, NO-N point can drive
resistive loads: 125VAC/1A, 230VAC/1A, 30VDC/1A.
5.2 RS485/CAN communication port
This port is an RS485 communication port
;;;
This port is an CAN communication port is an optional function, which is not available in the standard
machine.
This port is an RS485 communication port which comes with two functions
(
either-or
)
:
① RS485 communication with lithium battery BMS can be conducted
directly through this port RS485 (need to be customized);
② RS485 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
parameters and status of the reverse control all-in-one machine can be checked through the mobile APP.
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 port
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
.
