Working Principle
The module receives raw electrical signals from field sensors or controller outputs. It applies galvanic isolation and conditions the signal to the required specification. The processed signal is then output to the destination device, ensuring electrical separation and signal integrity between different parts of the control system.
Installation Requirements
- Install in a clean, dry control panel with adequate ventilation.
- Use properly sized and shielded wiring for all field connections.
- Ensure a solid equipment ground connection for optimal EMI immunity.
Usage Precautions
- Verify signal types and ranges before connecting field devices.
- Do not exceed the maximum voltage or current ratings of any channel.
- Check terminal tightness periodically to prevent intermittent connections.
