Product Description
Overview
The Emerson KJ3201X1-EA1 is a high-density 8-channel analog output terminal block with integrated HART pass-through. Designed for the DeltaV™ Distributed Control System, it connects smart field devices such as control valves and actuators to S-Series Analog Output modules, enabling both standard 4–20 mA signaling and digital HART communication for advanced monitoring and configuration.
Key Features
-
HART Digital Communication: Supports secondary variable readouts, device diagnostics, and calibration without extra hardware.
-
Smart Device Management: Fully compatible with Asset Management Solutions (AMS) for remote configuration and predictive maintenance.
-
Signal Accuracy & Noise Immunity: Optimized to reduce cross-talk and interference across all 8 channels.
-
Modular Design: Snap-on installation to S-Series carriers, allowing quick replacement without disturbing other modules.
-
Clear Channel Identification: Each termination point is labeled, minimizing wiring errors during installation.
-
Industrial Robustness: Operates from -40°C to 70°C with G3 conformal coating for harsh environmental resistance.
