Emerson KJ3212X1-BK1 DeltaV S-Series Pulse Count Input Card
An S-Series input card for pulse-count field signals, with published bus, field-power and hazardous-area installation limits.
Technical Summary
PRODUCT CONTEXTKJ3212X1-BK1 is the Emerson DeltaV S-Series Pulse Count Input Card identified in the manufacturer ATEX instruction sheet. It uses 12 V DC local-bus power and a 24 V DC bussed field supply, with each field circuit rated at 24 V DC and 25 mA per channel.
The card uses rotary terminal-block key position C6. The complete suffix, installed terminal block, carrier location and loop schedule should remain together because the keying and field-power arrangement define the physical installation.

Features
FUNCTIONAL DISTINCTIONSPulse-count acquisition
Processes pulse inputs as an identified S-Series I/O function rather than as a general digital-input substitute.
Controlled terminal pairing
Rotary key position C6 helps prevent connection to an incorrectly keyed terminal block.
Published environmental envelope
Temperature, shock, vibration, humidity and G3 contaminant limits are stated for the module.
No field calibration routine
Emerson states that calibration is not required and that the card contains no user-serviceable parts.
Compatibility
SELECTION BOUNDARIESCarrier and terminal block
Match the DeltaV S-Series carrier position and a terminal block keyed C6 before approving a spare.
Field-power design
Confirm the 24 V DC bussed source and the current demand of every active field circuit.
Hazardous-area installation
Apply the approval and enclosure requirements of the installed site; an I/O loop assessment and approved Zone 2 instructions remain part of the installation record.
Replacement
SERVICE WORKFLOWDocument
Capture the complete KJ3212X1-BK1 label, carrier slot, C6 terminal key, field-power source and pulse-channel assignments.
Isolate
Remove system and field power in accordance with the approved procedure before disconnecting or inserting the card.
Prove
Restore the configured channel record and verify pulse counting, diagnostics and any process interlocks with a controlled test source.
FAQ
CUSTOMER DECISION SUPPORTWhat power information should accompany a KJ3212X1-BK1 enquiry?
Provide the 12 V local-bus load, 24 V bussed field-power arrangement, active channel count and the installed supply record.
Can KJ3212X1-BK1 be removed with the DeltaV carrier energized?
No. Emerson states that this unit cannot be removed or inserted with system power energized.
Why does terminal key C6 matter for KJ3212X1-BK1?
The rotary keying system pairs the card with the intended terminal block and helps prevent an incompatible field connection.
Does KJ3212X1-BK1 require routine calibration?
Emerson states that calibration is not required; the card must not be disassembled because it has no user-serviceable parts.
What closes a KJ3212X1-BK1 replacement record?
Document correct module recognition, stable diagnostics and a verified count response for each commissioned pulse channel.
