Working Principle:
The KJ4001X1-CH1 terminal block receives the resistance signal from field-mounted RTD sensors through its screw terminals. The terminal block routes this signal through the carrier backplane to the corresponding analog input card, which converts the resistance value into a temperature reading. The terminal block itself is a passive interface — it provides the physical connection point without active signal processing.
Installation Requirements:
- Mount the terminal block onto the appropriate DeltaV I/O carrier
- Connect RTD sensor leads to the designated terminals following the wiring diagram
- Ensure proper wire gauge and torque specifications for terminal screws
- Verify terminal block keying matches the I/O card configuration
- Route sensor cables away from high-voltage power cables to minimize noise
Usage Precautions:
- De-energize field circuits before making or breaking terminal connections
- Verify RTD wiring configuration (2-wire, 3-wire, or 4-wire) matches the I/O card settings
- Do not exceed the terminal block voltage and current ratings
- Inspect terminals periodically for looseness or corrosion
- Use shielded cables for RTD connections in electrically noisy environments
