Receives 24 VDC dry-contact field states within the documented DeltaV electrical architecture.
Product Overview
KJ3201X1-BA2 is an Emerson DeltaV Series 2 digital input card for 24 VDC dry-contact circuits. The complete BA2 suffix and B1 terminal-block key are part of its installed identity.
Manufacturer instructions specify local-bus, bussed-field-power and per-channel field-circuit requirements and prohibit insertion or removal while system power is energized.
The module has no user-serviceable parts and requires no calibration; replacement readiness depends on correct keying, field wiring, environment and diagnostics.
Performance
Draws local-bus and bussed-field power at the published module values.
Uses B1 keying to support correct terminal-block association.
Provides digital input status to the DeltaV system without a field calibration procedure.

System Integration
- Remove system and field power before inserting, removing or connecting the card.
- Record the BA2 label, carrier location, terminal-block key and point assignment.
- Inspect terminal seating, keying, field voltage, grounding and environmental condition.
- Verify channel states, diagnostics, interlocks and approved process response after replacement.
Applications
- DeltaV discrete input circuits using approved dry contacts.
- Process interlocks, equipment-status and permissive signals in compatible DeltaV I/O carriers.
- Exact BA2 replacement where the B1 terminal block and system release are documented.
- Controlled maintenance in hazardous-area installations covered by the exact approval instructions.
FAQ
May KJ3201X1-BA2 be removed while the DeltaV system is energized?
No. Emerson instructs that the unit not be removed or inserted with system power energized, and field power must be removed before connection work.
What keying evidence should accompany a KJ3201X1-BA2 enquiry?
Provide the module label, B1 terminal-block key, carrier location and clear front and side photographs.
Does KJ3201X1-BA2 require field calibration?
No calibration is required, but channel logic, wiring state and system diagnostics still require functional verification.
What environmental record matters for a stored KJ3201X1-BA2 spare?
Document storage temperature, humidity control, ESD protection, connector protection and package identity.
What proves KJ3201X1-BA2 is ready after exchange?
Confirm exact BA2 identity, correct B1 keying, normal diagnostics and point-by-point input and interlock tests.
