Working Principle:
The card receives 4–20 mA current loop signals from field transmitters. Each channel converts the analog current into a digital value through precision analog-to-digital conversion circuitry. The HART modem superimposes digital communication on the same 4–20 mA wiring, allowing simultaneous analog measurement and digital data exchange with smart instruments. Digitized values are transmitted via the DeltaV I/O bus to the controller for real-time process computation and display.
Installation Requirements:
- Mount the card onto the KJ4001X1-CA1 carrier base inside a DeltaV I/O chassis
- Use shielded twisted-pair cables for field signal wiring
- Ensure proper grounding of cable shields at one end only
- Maintain cabinet ambient temperature within -40°C to +70°C
- Allow adequate ventilation around the chassis for heat dissipation
Usage Precautions:
- Verify HART instrument compatibility before connecting smart transmitters
- Perform loop checks after wiring to confirm signal integrity
- Do not insert or remove the card while the carrier is energized unless the system supports hot-swap
- Monitor LED diagnostics for channel fault indication
- Store spare cards in anti-static packaging at temperatures between -40°C and +85°C
