Working Principle
The KJ4001X1-CA1 operates as a signal termination interface within the DeltaV I/O architecture.
Typical signal flow:
Field Instrument → Standard I/O Terminal Block → DeltaV I/O Module → Controller → Operator Interface
Operating process:
- Field instruments generate process signals according to measured conditions.
- Signals enter the terminal block through field wiring connections.
- The terminal block organizes and transfers signals to connected DeltaV I/O modules.
- The I/O module performs signal processing and conversion.
- The controller uses the collected data for monitoring and process control.
The terminal block provides a reliable connection path but does not independently perform signal processing.
