Installation and Wiring Guide
Installation Steps
- Confirm the installation location, avoiding strong vibration, corrosive gases, and extreme temperatures.
- Fix the RIA45 in the panel or field housing, ensuring the sealing ring is intact.
- Connect the power supply, input signal, and output load according to the wiring diagram.
- After checking that the wiring is correct, power on and enter the parameter setting menu.
- Configure the input, display, and alarm parameters according to the actual signal type and range.
Wiring Precautions
- Use shielded cables, with the shielding layer grounded at one end.
- Route signal cables separately from power cables to avoid interference.
- The relay output load must not exceed the rated value.
- Ensure that the loop power supply voltage is within the allowable range.
Selection and Ordering Information
The following information must be clarified during selection:
- Input signal type: 4-20 mA, RTD, or thermocouple, etc.
- Output requirements: whether relays or analog output are needed
- Housing type: field type or panel-mounted type
- Certification requirements: explosion-proof, classification society, etc.
For specific model codes, refer to the selection table in the RIA45 Chinese manual.
