Cold Junction Compensation and Channel Isolation
- Thermocouple and RTD Signal Routing: Routes up to 32 field-side thermocouple or RTD input conductors directly to Series 1 and Series 2 DeltaV I/O modules through low-resistance screw-terminal termination points.
- Cold Junction Compensation (CJC) Support: Maintains isothermal terminal block conditions across all 32 channels to enable precise Cold Junction Compensation (CJC) calculations by adjacent temperature input cards.
- Hazardous Area Isolation: Certified to IECEx and ATEX standards for deployment in hazardous environment locations with ambient relative humidity ranges from 0% to 95% non-condensing.
Frequently Asked Questions
Q: What conductor wire gauge ranges are supported by the KJ4001X1-CG1 screw terminals?
A: The screw terminals accept solid or stranded field conductors ranging from 14 AWG to 22 AWG.
Q: Is the KJ4001X1-CG1 compatible with both Series 1 and Series 2 I/O carriers?
A: Yes, the 32-channel terminal block interface is engineered for direct mechanical and electrical alignment with both Series 1 and Series 2 DeltaV I/O module bases.
Q: Can the terminal block be safely detached without disconnecting field sensor wiring?
A: Yes, the module unplugging mechanism allows field technicians to remove the terminal block assembly from the carrier during hardware maintenance without disturbing field cabling terminations.
Field Installation Guidelines
- Carrier Slot Mounting: Align the terminal block guides with the designated I/O carrier slot and press firmly until the mechanical retention clips latch into position.
- Shield Drain Wiring: Connect all individual thermocouple and RTD cable shield drain wires directly to the carrier earth ground bar to preserve signal integrity against electromagnetic interference.
- Screw Terminal Torque: Tighten wire clamp screws for all connected 14 AWG to 22 AWG field conductors to a torque specification of 0.5 to 0.6 Nm to ensure gas-tight electrical contact.
- Hazardous Area Compliance: Verify that enclosure seals maintain the IP66 ingress protection rating and satisfy ATEX/IECEx installation code requirements prior to applying loop power.
