Wiring instructions
| Types | Logo | Description | Remarks |
|---|---|---|---|
| Power input and communication | VCC | Power input positive | 10~30V DC |
| GND | Power input ground | ||
| 485A | 485-A | Communication | |
| 485B | 485-B | ||
| Power output and signal input | VCC | Power output positive | Power output, module to equipment |
| GND | Power output ground | ||
| IN0 | Analog 1 input | Common for two-wire, three-wire, and four-wire system | |
| IN1 | Analog 2 input |
The conversion module only needs one end of the power supply to be able to work normally, and the other end of the power supply is prepared for the subsequent stage power supply. If the latter stage is not powered, it can be left floating.
When multiple 485 models are connected to the same bus, there are certain requirements for on-site wiring, please contact us for details.
Input signal wiring example
| Wire system | VCC | GND | IN0 | IN1 |
|---|---|---|---|---|
| Two-wire system | Device power is positive | Air | Analog input 1 | Analog input 2 |
| Three-wire system | Equipment power ground | Analog input 1 | Analog input 2 | |
| Four-wire system | Equipment power ground analog input negative | Analog input 1 positive | Analog input 2 positive |
