Provides isolated sensor interfacing inside the DeltaV S-Series I/O architecture.
Technical Summary
KJ3231X1-BK1 is an Emerson DeltaV S-Series isolated input card. It mounts to an S-Series I/O interface carrier, mates with the applicable terminal block and provides isolated interfaces for up to four sensors.
Its selection boundary includes the complete BK1 identity, carrier, keyed terminal block, sensor type and configured channel range; it is not interchangeable with higher-density standard analog-input cards by appearance.

Features
Uses a pluggable card arrangement between the carrier and field terminal block.
Supports up to four isolated sensor connections in the documented card design.
Keeps card keying and terminal selection as mechanical safeguards against an incorrect I/O type.
Compatibility
- Confirm the full KJ3231X1-BK1 label and the applicable S-Series carrier and terminal-block assembly.
- Record each configured sensor type, range, wiring method, isolation requirement and channel assignment.
- Verify the terminal-block keying before mating the card; do not defeat or alter the key arrangement.
- Compare DeltaV hardware revision and controller software support before approving a replacement.
Replacement
- Save the I/O configuration and capture every field-wire and terminal designation before removal.
- Follow the approved DeltaV procedure for field power and system power before inserting or removing the card.
- After installation, verify card recognition and test every affected input with an approved signal source.
- Retain the BK1 release, terminal identity and proof-test results in the maintenance record.
FAQ
Can KJ3231X1-BK1 replace a standard eight-channel analog input card?
Not as a like-for-like spare. Its isolated four-sensor architecture and required terminal arrangement create a different selection boundary.
What field information is needed for a KJ3231X1-BK1 quotation?
Provide the card and terminal labels, carrier position, configured sensor types and ranges, channel list, DeltaV release and required quantity.
Why does terminal-block keying matter for KJ3231X1-BK1?
The keying helps prevent an incompatible card and terminal assembly from being mated, so the installed position must be recorded and preserved.
Can KJ3231X1-BK1 be exchanged with power applied?
Use only the conditions and procedure stated for the installed DeltaV system and hazardous-area classification; do not assume hot-swap permission.
What proves the replacement isolated-input card is ready for service?
Confirm correct recognition, stable readings, channel isolation, expected sensor response and successful testing of every affected loop.
