KJ4001X1-BA3 | Emerson DeltaV System Power Supply Module

Product Overview

The Emerson KJ4001X1-BA3 serves as the primary System Power Supply for the DeltaV™ Distributed Control System (DCS). This module delivers regulated, high-amperage power to DeltaV controllers and I/O modules, maintaining the electrical backbone of the entire control architecture. It eliminates voltage fluctuations that could otherwise lead to system resets or data corruption. We supply this unit as 100% Brand New and Original, ensuring your mission-critical automation hardware operates with factory-certified electrical stability.

Technical Specifications

The KJ4001X1-BA3 features robust input ratings and extreme environmental hardening to support continuous operation in industrial cabinets.

• Input Power: 30 VDC at 8 A

• Operating Temperature: -40°C to +70°C (-40°F to +158°F)

• Airborne Contaminants: ISA-S71.04–1985 Class G3 (Harsh Environment)

• Relative Humidity: 5% to 95% (Non-Condensing)

• Shock Resistance: 10g, ½ Sinewave for 11 msec

• Vibration Resistance (Low Freq): 1mm Peak to Peak (2 to 13.2 Hz)

• Vibration Resistance (High Freq): 0.7g (13.2 to 150 Hz)

Engineering Advantages

• Harsh Chemical Resistance: This module carries an ISA-S71.04 Class G3 rating. This provides a specialized chemical shield against corrosive gases like Hydrogen Sulfide ($H_2S$) and Chlorine, preventing the "whisker" growth and contact oxidation that typically cause power failures in refineries and wastewater plants.

• Extreme Thermal Endurance: The KJ4001X1-BA3 operates across a massive temperature window of -40°C to +70°C. It powers your control system reliably in unheated arctic enclosures or high-heat desert environments without requiring external cooling fans.

• Mechanical Hardening: The hardware survives 10g of shock and specific vibration profiles. This durability ensures that the power supply maintains a constant connection to the backplane even when mounted in cabinets directly adjacent to heavy reciprocating pumps or compressors.

• High-Current Delivery: A robust 8 A output capacity allows a single KJ4001X1-BA3 to support a dense configuration of controllers and I/O cards, effectively reducing the number of power modules required and saving valuable DIN rail space.

FAQs

Q: Is the KJ4001X1-BA3 provided in its original Emerson factory packaging?

A: Yes. We supply only 100% Brand New units. Each module arrives in its original Emerson packaging with intact anti-static sealing and verified serial numbers, ensuring it meets all current safety and performance standards.

Q: Does the KJ4001X1-BA3 support redundant power configurations?

A: Yes. When installed on a redundant power carrier, two KJ4001X1-BA3 modules work in parallel. If one supply fails, the other instantaneously carries the full load (up to its 8 A rating) to prevent any interruption to the DeltaV system.

Q: Can I use this power supply in high-humidity offshore environments?

A: Absolutely. The module handles 95% non-condensing humidity and features G3-rated corrosion protection. This makes it an ideal choice for offshore platforms and coastal facilities where salt air and moisture typically degrade standard industrial electronics.

Q: Does this module require periodic calibration or maintenance?

A: No. The KJ4001X1-BA3 utilizes a solid-state, maintenance-free design. It continuously monitors its own output and provides status feedback to the DeltaV system software, eliminating the need for manual voltage adjustments or physical maintenance.
