Modbus address: 40051--40058

Function code: 03, address: 50

Factory Default: Current Input: 4-20mA, 0-20mA [Compatible]

Voltage input: 0-5V, 1-5V, 0-10V

Change the type in two steps:

1. Open "AI Configuration Software" and select the type;

2. Open the module cover, each channel has a jumper cap:

---Short 2 pins on the side of the 'chip': "voltage type"

---Short 2 pins on the 'terminal' side: "current type"

Data precision: 0.1% precision, 12 bits

Refresh frequency: 0.1 seconds to update all I/O point data

The corresponding value divided by 1000 is the actual signal size:

4～20mA: 4000～20000 <16-bit integer>

0～20mA: 0000～20000

0～5V: 0000～5000

0～10V: 0000～10000

Current and voltage calculation formula:

Example: read 40051 register data == 4000

Then the corresponding current = 4000 / 1000 = 4mA

Two-wire connection:

The meter is connected to the positive power supply;

The instrument is negatively connected to AI;

The power supply is negatively connected to AI-COM;

Three-wire connection:

The meter is connected to AI;

The instrument is negatively connected to COM;

Four-wire connection:

The meter is connected to AI;

The instrument is negatively connected to COM;

Function 1: Modify the corresponding value;

Factory default 4-20mA correspondence: 4000-20000 <register>

Function 2: Modify the signal type:

0-5V, 1-5V, 0-10V, 0-20mA;

4-20mA minimum 0mA: AI=0 when the wire is disconnected, it is convenient for users to check whether the wiring is bad;

4-20mA minimum 4mA: AI=4mA when disconnected, that is, AI reading is always greater than 4mA;

Modbus address: 10001～10016: Corresponding channel number

Wet Node Wiring Method

Both NPN/PNP sensors can be connected: COM can be connected to positive or negative

Dry Node Wiring Method

One end of the customer's switch equipment is connected to the positive power supply of the module, the other end is connected to DI, and the DICOM is connected to the negative power supply of the module.

Detection scheme

1. The module power supply is connected to DI, and the module power supply is negatively connected to DICOM

2. "Module test software.exe" test reading

3. The signal can be read to indicate that the DI function is normal

4. If the signal cannot be read, use a multimeter to measure whether there is a 5-30V voltage across DI and COM
