Working Principle:
The card accepts 4-20 mA signals from up to 8 field devices simultaneously. Each channel independently conditions and converts the analog current to digital values for the DeltaV controller. The HART communication subsystem extracts digital data from the analog signal, enabling access to device diagnostics, multiple process variables, and configuration parameters. The 4-wire configuration supports devices requiring external power, making it versatile for various transmitter types.
Installation Requirements:
- Mount in DeltaV I/O carrier on DIN rail
- Connect 4-wire field devices to appropriate terminals
- Ensure proper shielding and grounding
