Product Description
Overview
The Emerson KJ3242X1-BA1 (12P3162X012) is an 8-channel analog output module for the DeltaV M-Series DCS, designed to drive field devices requiring variable current signals such as control valve actuators, variable speed drives, and positioners. This module converts digital commands from the DeltaV controller into precise 4-20 mA or 0-20 mA outputs. Its integrated HART (Highway Addressable Remote Transducer) capability allows digital communication and diagnostics to be transmitted over the same two wires as the analog signal.
Key Features
Integrated HART Communication
Each of the 8 channels functions as a HART modem, enabling real-time access to secondary device variables, remote calibration, and detailed diagnostic monitoring of field instruments without requiring physical presence in the field.
High Precision and Stability
The module ensures accurate analog output with high-resolution digital-to-analog conversion and minimal temperature drift, maintaining precise control in fluctuating environmental conditions.
Open Circuit Detection
Built-in diagnostics monitor the integrity of each output loop, detecting broken wiring or disconnected devices and reporting faults directly to the controller and HMI.
Galvanic Isolation
The card is electrically isolated from the LocalBus and adjacent modules, preventing electrical noise or ground loops from affecting controller logic or other I/O modules.
Hot-Swappable and Auto-Sensing
Modules can be replaced while the system is powered, and the DeltaV system automatically recognizes and configures the new card with its pre-set parameters.
