POWER light: Displays the power status
RUN light: module running indication, flashes once per second
485 lights: RS485 send data indication
232 lights: RS232 send data indication
IO lights: Each digital IO has a corresponding indicator light
Modbus address: 40059--40074
Function code: 03, address: 58
Factory default: current input: 4-20mA, 0-20mA [compatible]
Voltage input: 0-5V, 1-5V, 0-10V
Two steps to change the type:
1. Open "AI Configuration Software" and select the type;
2. Open the cover of the module, each channel has a jumper cap:
---Short 2 pins on one side of the 'chip': "voltage type"
---Short 2 pins on one side of the 'terminal': "current type"
Data accuracy: 0.1% accuracy, 12 bits
Refresh frequency: update all I/O point data once in 0.1 seconds
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:
register reading / 1000
Example: read 40051 register data == 4000
Then the corresponding current = 4000 / 1000 = 4mA
​
Two-wire connection:
The meter is positively connected to the power supply;
The meter is negatively connected to AI;
The power supply is negatively connected to AI-COM;
Three-wire connection:
The instrument is connected to AI;
The meter is negatively connected to COM;
Four-wire connection:
The instrument is connected to AI;
The meter is negatively connected to COM;
Function 1: modify the corresponding value;
Factory default 4-20mA corresponding: 4000-20000<register>
Function 2: Modify the signal type:
0-5V, 1-5V, 0-10V, 0-20mA;
4-20mA minimum 0mA: AI=0 when disconnected, it is convenient for users to check whether the connection is bad;
4-20mA minimum 4mA: AI=4mA when the line is disconnected, that is, the AI reading is always greater than 4mA;
Modbus register: 40051--40058
Function code: 03, address 50
Temperature range: -200 to 320°C
