Emerson DeltaV KJ3003X1-EA1 Terminal Block Serial Interface Module

Product Overview

The Emerson KJ3003X1-EA1 functions as a high-integrity serial interface terminal block within the DeltaV control ecosystem. This module provides the physical connection point and electrical conditioning necessary for robust serial data transmission. It bridges the gap between field-level serial devices and the controller, ensuring seamless data flow in complex process automation environments.

Technical Specifications

The KJ3003X1-EA1 meets rigorous industrial electrical standards to ensure continuous uptime:

Engineering Advantages

• Superior Vibration Tolerance: The unit withstands 10G sinewave shock for 11 milliseconds. This mechanical resilience prevents signal intermittent failures in high-vibration environments like pump rooms or turbine decks.

• Thermal Versatility: The wide operating range (-40°C to +70°C) allows installation in unconditioned remote instrument enclosures (RIEs) without requiring external cooling or heating elements.

• Space-Efficient Design: At only 0.20 lbs, this lightweight terminal block maximizes DIN rail density, allowing engineers to pack more serial interfaces into smaller cabinet footprints.

• Stable Power Delivery: The 1.0 Amp current capacity ensures stable power distribution to connected serial peripherals, eliminating voltage drops that often plague lower-rated generic terminal blocks.

FAQs

• Does this unit arrive in original Emerson packaging?

  Yes. We supply the KJ3003X1-EA1 as 100% Brand New equipment in its original factory-sealed box to guarantee authenticity and performance.

• Can this module handle high-voltage spikes?

  The module is rated for 35 VDC operation. It provides a stable interface for low-voltage serial communications and includes basic circuit protection, though we recommend standard surge suppression for long-distance field runs.

• What are the mounting requirements for the KJ3003X1-EA1?

  This terminal block snaps directly onto standard DeltaV carrier rails. Its lightweight design ensures it remains secure even during the specified 10G shock events.

• Is there a difference between the EA1 and older revisions?

  The EA1 suffix denotes a specific hardware revision optimized for current DeltaV Series 2 or M-series hardware. It maintains the 1.0 Amp rating required for modern serial interface modules.
