More Information

Overview Manuals Redundant AO Path A5 Identification Maintenance State Product Applications

Features:

  • Redundant AO role: the 48-pin block supports an Analog Output Plus redundancy path
  • A5 key position: mechanical keying identifies the intended I/O card interface
  • 200 mA channel rating: field circuits are specified at 30 VDC
KC4011X1-BZ1 is the field-termination element in a redundant DeltaV analog-output arrangement, not a complete card pair.

The A5 setting and lower 200 mA-per-channel rating distinguish it from the nearby simplex AI mass terminal block.

A safe service sequence begins by removing the I/O card and disconnecting field wiring before any powered terminal-block movement.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Output role: the block serves the Analog Output Plus field interface.
  • Redundancy: the terminal arrangement is designed for the redundant card path.
  • Connector format: 48 pins carry the mass-termination interface.
  • Electrical limit: each field circuit is rated 30 VDC at 200 mA.
  • Published key: the required rotary position is A5.
  • Mechanical control: keying must correspond to the associated AO card.
  • Suffix distinction: BZ1 identifies this redundant output block.
  • Receiving record: label, key position, connector, and enclosure location should agree.
  • Card condition: no I/O card may remain installed during powered removal.
  • Field condition: all field wiring must be disconnected for the same operation.
  • Adjustment: calibration is not required.
  • Repair: the component has no user-serviceable internal parts.
  • Redundant process outputs: terminate the AO Plus field path in a DeltaV redundancy design.
  • Marshalling-panel replacement: restore the 48-pin field interface without changing signal identity.
  • Planned redundancy maintenance: separate card and field wiring before powered terminal-block movement.
  • Industrial cabinet deployment: qualify the enclosure against the stated environmental limits.
Description
KC4011X1-BZ1 provides the redundant 48-pin mass-termination interface for a DeltaV Analog Output Plus arrangement. Its purpose is to carry the field-side output connections while preserving the redundant card architecture defined by the cabinet design.

Where the BW1 model serves simplex analog input, KC4011X1-BZ1 is identified by its redundant AO role, A5 rotary key position, and 30 VDC at 200 mA-per-channel field-circuit rating. These three facts prevent a visually similar terminal block from being assigned to the wrong signal path.

Maintenance of KC4011X1-BZ1 is governed by state, not appearance. Emerson permits powered insertion or removal only with both the I/O card absent and field wiring disconnected; the component itself needs no calibration and must not be opened for repair.
Alternative Names
KC4011X1BZ1 12P4012X032 redundant AO terminal block DeltaV A5 48-pin AO mass terminal block Redundant AO Plus mass termination block
Technical notes
KC4011X1-BZ1 belongs to the redundant AO Plus mass-termination path and uses A5 keying; do not apply the BW1 simplex-AI identity or 500 mA rating. Powered removal is permitted only after the I/O card is absent and every field conductor is disconnected. Internal servicing is prohibited, and calibration is not required.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How is KC4011X1-BZ1 different from a simplex AI terminal block?
It is a redundant Analog Output Plus mass terminal block, uses A5 keying, and carries a 30 VDC at 200 mA-per-channel field rating.
What does redundancy mean for KC4011X1-BZ1?
The terminal block belongs to a redundant AO card architecture. It does not by itself supply the two output cards or establish the controller-side redundancy configuration.
When can KC4011X1-BZ1 be moved with system power present?
Only after the I/O card has been removed and all field wiring is disconnected. If either condition is not met, follow the approved isolation and shutdown plan.
Which key position should KC4011X1-BZ1 use?
Set the rotary key to A5 and verify that the intended AO card carries the corresponding mechanical key identity before insertion.
Can technicians repair or calibrate KC4011X1-BZ1?
No calibration is required, and Emerson states that there are no user-serviceable parts. A damaged or contaminated enclosure should not be opened for field repair.
What should be captured before replacing KC4011X1-BZ1?
Photograph the model label, A5 setting, redundant card arrangement, 48-pin connection, channel schedule, field-wire state, enclosure position, and any failure evidence.
