Product Details

Product Overview

The Emerson KJ3223X1-EA1 serves as the essential Analog Input Terminal Block for the DeltaV M-series I/O subsystem. This module provides the physical and electrical interface required to connect field transmitters to the DeltaV control network. It facilitates the transition of analog signals (typically 4–20 mA or ±10 VDC) from sensors into the I/O electronics card. By providing dedicated termination points and bussed field power, the KJ3223X1-EA1 ensures secure, noise-free signal acquisition for critical monitoring tasks in refineries, power plants, and chemical processing facilities.

Engineering Advantages

Optimized Signal Integrity: The KJ3223X1-EA1 utilizes high-integrity terminal connections that minimize contact resistance. This ensures that low-level analog signals reach the A/D converter without distortion, maintaining the ±0.1% accuracy required for precision process control.

Integrated Field Power Distribution: The module features a bussed field power rating of 24 VDC at 32 mA. This internal distribution simplifies cabinet wiring by providing power directly to 2-wire transmitters through the terminal block, eliminating the need for complex external fuse blocks for every channel.

Galvanic Isolation Architecture: When paired with the appropriate DeltaV AI card, this terminal module supports full channel-to-channel and system isolation. This configuration blocks ground loops and prevents field-side electrical surges from damaging the central DeltaV controller.

Rugged Modular Design: The compact footprint (approx. 107 × 41 × 105 mm) maximizes rail density in marshalling cabinets. The module withstands harsh industrial temperatures ranging from 0°C to +60°C, ensuring continuous operation near heat-generating equipment.

Simplified Maintenance via Hot-Swapping: The terminal module supports the DeltaV "Plug-and-Play" philosophy. Maintenance teams can replace the associated I/O card while the terminal block remains wired, drastically reducing downtime during hardware upgrades or repairs.

FAQs

Q1: Is the Emerson KJ3223X1-EA1 supplied as a new unit?

A1: Yes. We supply the KJ3223X1-EA1 in 100% Brand New and Original condition, complete with factory-sealed packaging. We include a standard 12-month warranty to ensure long-term reliability.

Q2: What is the typical lead time for shipping?

A2: We typically ship this module within 1 to 2 weeks. For urgent requirements, we utilize premium couriers such as FEDEX or DHL to ensure rapid delivery to your site.

Q3: Does this terminal block include the Analog Input electronics card?

A3: This part number refers specifically to the Terminal Block Module. While it provides the interface for 8 analog channels, the electronics module (I/O card) is a separate component that plugs into this terminal base.

Q4: Can I use this terminal block for both 4-20mA and voltage inputs?

A4: Yes. The KJ3223X1-EA1 supports both 4–20 mA DC and ±10 V DC signal types. The actual signal processing is determined by the configuration of the specific DeltaV Analog Input card you pair with this terminal block.
