Analog interface: Analog interface is optional, interface signals can be customized,
two analog interface definition as shown in the table above
RS485 interface: Serial communication interface(female), software using standard
Modbus-RTU protocol;
CAN interface: CAN1 and CAN2 are two internal parallel CAN bus interfaces, which
facilitate serial or parallel connection between devices. CAN communication also be
used for communication between external devices;
Note
：
Analog interface is optional interface (customizable) , up to a maximum of four analog, two
analog input and two analog output. Select 1-2 analog, interface see figure above; select 3-4
analog, interface is RJ45-CAN1, 1-8 pin is defined as the positive and negative of analog
input 1, the positive and negative of analog input 2, the positive and negative of analog
output 1, the positive and negative of analog output 2. If you need analog function, please
inform us of the specific requirements in advance

1.2 Voltage compensation
Figure 3: Schematic diagram of voltage compensation wiring
To use the remote voltage compensation function, use twisted-pair cables with high
insulation. Positive and negative cables can not be connected inversely, as shown in the
figure above. When not in use, the compensation terminals (SENSE) PIN1 and PIN2, and
PIN3 and PIN4 need to be shorted with short cables.
1.3 Parallel connection
Figure 4: Parallel schematic diagram
The device identifies and controls the parallel output through CAN communication. The
diagram above shows the parallel connection.
Note:120 ohm is the CAN bus terminal resistor.
