Product Overview

KJ3203X1-BA1 is an Emerson DeltaV M-series Series 2 discrete input card for 32 channels of 24 VDC dry-contact signals.

The official M-series Traditional I/O data sheet specifies greater than 2 mA as the ON detection level, less than 0.25 mA as the OFF detection level, approximately 5 kohm input impedance and a common return.

The exact Emerson instruction sheet identifies 12 VDC LocalBus power at 75 mA, 24 VDC bussed field power at 150 mA, 24 VDC field circuits at 5 mA per channel, B3 terminal-block keying and an IP20 component rating.

Applications & Features

Thirty-two dry-contact inputs

The card consolidates 32 discrete field contacts in one DeltaV M-series Series 2 module.

Defined switching thresholds

The published ON level is greater than 2 mA and the OFF level is less than 0.25 mA.

System isolation

Every channel is optically isolated from the DeltaV system and factory tested to 1500 VDC.

Common-return architecture

All 32 inputs use the card's published common-return arrangement with a 32-screw terminal block.

Connections

Field inputs	Thirty-two 24 VDC dry-contact channels.
Terminal block	Use the compatible 32-screw termination block with B3 rotary keying.
LocalBus	12 VDC nominal; 50 mA typical and 75 mA maximum.
Bussed field power	24 VDC at 150 mA for the card.
Channel circuit	24 VDC at 5 mA per channel on the exact instruction sheet.
Return wiring	Common return as specified for the 32-channel dry-contact input card.

Installation

01 - Verify the complete model

Match KJ3203X1-BA1 on the quotation, product label and dated photographs; do not confuse it with KJ3202X1-BA1 or KJ3204X1-BA1.

02 - Confirm the input application

Use the card only for the specified 32 channels of 24 VDC dry-contact discrete input signals.

03 - Set terminal keying

Use a compatible terminal block keyed to position B3 before mating the field terminal assembly.

04 - Check power and wiring

Confirm 12 VDC LocalBus power, 24 VDC bussed field power, common-return wiring and the 5 mA per-channel field-circuit rating.

05 - Apply hazardous-area procedures

De-energize non-sparking field circuits before removal or insertion and follow Emerson document 12P2046 and the exact instruction sheet.

Environment

Ambient temperature

-40 to +70 degrees C on the exact KJ3203X1-BA1 instruction sheet.

Protection

IP20 component; install in the enclosure required by the site and certification.

Humidity

5 to 95 percent relative humidity, non-condensing.

Shock and vibration

10 g half-sine for 11 ms; 1 mm peak-to-peak from 5 to 16 Hz and 0.5 g from 16 to 150 Hz.

Contaminants

ISA-S71.04-1985 airborne contaminants Class G3.

Maintenance

No user-serviceable parts and no calibration requirement are stated in the exact instruction sheet.

FAQ

Q1. How can the exact quoted KJ3203X1-BA1 be verified?

Match KJ3203X1-BA1 on the card label, quotation and date-marked photos. Confirm that the label identifies a 32-channel 24 VDC dry-contact discrete input card with B3 keying.

Q2. How can New, Used or Refurbished condition be distinguished?

Request current photos of the complete label, B3 keying, front indicators, rear contacts, terminal interface, housing and packaging. Look for insertion wear, repaired parts, altered labels or cleaning residue.

Q3. How should supplier legality and reliability be checked?

Verify the legal entity, registered address, payment beneficiary and traceable contact. The written offer must state Emerson, KJ3203X1-BA1, 32-channel DI card, condition and quantity.

Q4. Which specifications must engineering confirm before purchase?

Confirm 32 dry-contact inputs, 24 VDC field circuits, ON and OFF thresholds, 5 kohm input impedance, common return, B3 keying, 12 VDC LocalBus current and compatible 32-screw termination.

Q5. What physical evidence should be requested before payment?

Ask for one date-marked photo set showing the full nameplate, serial data, B3 key position, front indicators, rear contacts, terminal interface and sealed packaging when offered as new.

Q6. Can KJ3202X1-BA1 or KJ3204X1-BA1 replace KJ3203X1-BA1?

No. KJ3202X1-BA1 is an 8-channel high-side discrete output card and KJ3204X1-BA1 is a 32-channel high-side discrete output card. They differ in signal direction, channel function and keying from this 32-channel dry-contact input card.
