Redundant Field Termination and Signal Interface
The KJ4006X1-BK1 terminal block provides field wiring termination for DeltaV S-Series I/O configurations requiring redundant interface capability. The rotary keying mechanism defines compatibility between the terminal block and the associated I/O card. Therefore, the installed key position must match the assigned I/O card configuration before operation.
The terminal block supports hazardous atmosphere installation with Ex ec IIC Gc certification. In addition, the enclosure and electrical design maintain the required separation between field circuits and system-side connections according to DeltaV Zone 2 installation requirements.
The unit does not contain user-serviceable components. Furthermore, calibration is not required because the terminal block performs passive signal termination and interface functions rather than measurement processing.
Frequently Asked Questions
Q: Can the KJ4006X1-BK1 terminal block be removed while system power is applied?
A: The terminal block can be removed or inserted with system power applied only when no I/O card is installed and no field wiring is connected.
Q: How does the terminal block prevent incorrect I/O card installation?
A: The rotary keying system mechanically matches the terminal block with the assigned I/O card after installation. The key position must correspond to the selected I/O module.
Q: Does the KJ4006X1-BK1 require calibration or internal maintenance?
A: No. The terminal block contains no user-serviceable parts and does not require calibration adjustment.
Field Installation Guidelines
Install the KJ4006X1-BK1 according to the DeltaV S-Series and CHARMs Hardware Installation documentation and the DeltaV S-Series Digital Automation System Zone 2 Installation Instructions.
Verify the hazardous area certification marking before installation in classified locations. Also, confirm that the terminal block key position matches the intended I/O card before connecting field wiring.
Route field cables according to industrial control cabinet wiring practices. Maintain proper separation between signal wiring and high-energy circuits, and connect cable shields according to the site grounding design.
Before removing or inserting the terminal block, disconnect field wiring and verify the I/O card installation condition. Do not disassemble the terminal block because it contains no adjustable internal components.
