All wiring should be performed by qualified personnel. Ensure the power supply is disconnected before making any connections. The device requires a DC24V input.
2.3.1 پاور سپلائي ۽ گرائونڊنگ
Connect the FG (Frame Ground), 0V (Negative), and DC24V (Positive) terminals as shown in the rear view diagram. Proper grounding is essential for stable operation and safety.
2.3.2 Digital Input/Output Wiring
The digital input (X) is an externally powered DC24V sinker (passive NPN). The input signal is isolated from the power supply. Connect COM to the positive 24V of the external power supply while using. The digital output terminals are grouped, and each group is electrically isolated. For relay outputs, COM is common to the positive or negative. For transistor outputs, COM is common to the negative.

3.3 PLC Programming
The PLC can be programmed using Mitsubishi software such as GX Developer (versions 8.86 and 8.52) and GX Works2. Refer to the respective software manuals for detailed programming instructions.
3.3.1 Analog Input Register Operation
Analog input register operation is 12-bit precision. Input values can be read from D0 to D400. The constant scan time is 100. For temperature inputs, the corresponding value is the temperature in degrees Celsius, with a decimal point. For example، 182.0 ° C 1820 طور پيش ڪيو ويو آهي.
3.3.2 Analog Output Register Operation
Analog output register operation is 12-bit precision. Output channels (DA0-DA7) correspond to the analog output value. The set value range is 0-4000. For 0-20mA output, D8058.7=0. For 4-20mA output, D8058.7=1.
