Product Description
Overview
The Emerson KJ4001X1-BA3 (12P0547X092) is an 8-channel, 24 VDC high-side remote termination unit (RTU) engineered for seamless integration with Emerson’s DeltaV™ Distributed Control System. It provides a secure interface between digital output modules and field devices, ensuring reliable signal transmission and protection in complex industrial environments.
Designed for robust industrial use, the KJ4001X1-BA3 incorporates individual channel fusing, integrated diagnostic LEDs, and high-side switching for enhanced operational safety. Its compact footprint and modular design allow easy installation on DeltaV M-series and S-series carriers.
Key Features
Advanced Channel Protection
Each of the 8 channels has dedicated fusing, isolating faults to the affected output and preventing disruption to the remaining circuits.
High-Side Switching Architecture
Controls the positive power supply line to field devices, reducing the risk of accidental energization and improving safety in grounded fault conditions.
Visual Diagnostics
Equipped with channel status indicators and blown-fuse LEDs, enabling quick identification of failures without specialized test equipment.
Durable Industrial Design
-
Operating Temperature: -40°C to +70°C
-
G3 Conformal Coating for resistance against humidity, salt air, and corrosive gases
-
Vibration Resistance: 1 mm peak-to-peak (5–16 Hz) and 0.5 G (16–150 Hz)
-
Shock Resistance: 10 G, 11 ms sinewave
Simplified Installation
Pre-wired mass-termination cable connects to DeltaV I/O modules, minimizing wiring errors and reducing commissioning time.

FAQ
Q: Is the KJ4001X1-BA3 compatible with older DeltaV modules?
A: Yes, it maintains backward compatibility with most DeltaV systems, provided the field device current does not exceed fuse ratings.
Q: Can the unit handle continuous 8 A per channel?
A: Yes, but it should not exceed the rated maximum operating voltage of 30 VDC.
Q: What happens if one channel shorts?
A: The affected channel’s fuse will blow, isolating the fault while the remaining channels continue operation.
Q: Can this unit be used in hazardous areas?
A: Yes, it is rated for ATEX, UL, and FM Class 1 Div 2 environments.
