Emerson DeltaV KJ4001X1-CG1 Terminal Block

Configured for high-density temperature sensor field wiring in Emerson DeltaV DCS platforms, the Emerson DeltaV KJ4001X1-CG1 (KJ4001X1-CG1 32-Channel Terminal Block) provides direct physical/electrical execution.

Suffix Breakdown & Model Matrix

Hardware Specifications

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

1. 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.
2. 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.
3. 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.
4. 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.
