Analog Input And Output Wiring

Analog 0~20mA and 4-20mA current input wiring diagram

Analog 0~10V voltage input wiring diagram

Analog 0-20mA and 4-20mA Current Output Wiring Diagram

Analog 0-5V or 0-10V voltage output wiring diagram

Note: The GND of the analog input and output is used as the signal reference point, and it should be connected separately from the power supply 0V of the HJ3200/VM3200 module as much as possible to reduce the influence of the interference signal on the system acquisition.

Temperature input PT100/PT1000

Two-wire wiring (independent temperature input)

Two-wire wiring method (analog and temperature mixed type)

Three-wire (PT100/PT1000) wiring

K-type thermocouple wiring

Note: The temperature signal is a weak signal. It is recommended to connect it directly to the terminal of the device. Sometimes, if it must be connected to the module through the terminal block, the 0V terminal point of the power supply must be separated from the reference point of the temperature input, and cannot be connected to the same terminal.

as follows:

Single point load cell wiring method

Weighing module

One weighing channel per sensor

Multiple sensors connected to one weighing channel
