The Emerson KJ3243X1-BB1 (12P3994X042) is a DeltaV Series 2 Plus Profibus DP Interface Card. It provides high-speed, master-level communication between the DeltaV DCS and third-party field devices, supporting up to 64 slaves and 12 Mbaud transmission speeds.
The Emerson KJ3221X1-BA1 (Part Number 12P3994X042, Model VE4022) functions as a high-speed communication bridge within the DeltaV Series 2 Plus architecture. This Profibus DP (Decentralized Periphery) Interface Card enables the DeltaV Distributed Control System to exchange data seamlessly with remote I/O, motor control centers (MCCs), and smart field devices. By integrating the Profibus protocol, the card allows operators to access advanced diagnostics and process variables from third-party hardware, centralizing control within the DeltaV environment.
This module handles complex communication tasks by acting as a Profibus DP Master. It supports a wide range of transmission speeds and ensures deterministic data exchange for time-critical control loops. The “Series 2 Plus” designation indicates enhanced processing capabilities and memory, allowing for more robust device integration compared to standard legacy cards. The card manages the cyclic exchange of I/O data while simultaneously allowing for acyclic communication, which is vital for device configuration and monitoring of Epro vibration systems or similar specialized field instrumentation.
The Emerson DeltaV™ M-series KJ3002X1-BB1 (12P0683X092 / VE3006) is a legacy, high-precision thermocouple and mixed-signal I/O module designed for flexible process control within the DeltaV Distributed Control System (DCS). Capable of reading continuous analog variables alongside discrete status indicators, this modular card features built-in galvanic signal isolation, advanced thermocouple loop-burnout diagnostics, and high-density noise protection. Engineered for direct hot-swappable installation into M-series carriers, it delivers stable, industrial-grade data acquisition for critical temperature, flow, and pressure monitoring loops across harsh, high-interference manufacturing environments.
The Emerson DeltaV SIS™ KJ3001X1-BH1 (12P0558X152) is a legacy, high-performance isolated I/O interface card engineered for critical process safety and Distributed Control Systems (DCS). Providing robust electrical isolation to prevent ground loops and voltage spikes, this module features a field circuit rating of 60 VDC at 1 A per channel, a LocalBus power draw of 150 mA at 12 VDC, and a specialized B5 mechanical terminal block keying system to prevent incorrect field installation. Built to withstand punishing industrial conditions, its IP20-rated assembly is certified to ISA-S71.04-1985 Class G3 corrosion resistance standards, ensuring stable, interference-free safety loop communication in harsh, highly corrosive processing environments.
