KJ3002X1-BE1 | Emerson | AO, 8-Channel, 4-20 mA, HART Card

Description

KJ3002X1-BE1 is an Emerson analog output (AO) HART card, designed for industrial automation control systems. Based on comparable Emerson KJ3002 series cards, this unit is expected to feature 8 independent channels with 4-20 mA signal output and native HART communication support, enabling two-way digital communication with field devices alongside analog signal transmission.

Similar series models include optical channel isolation, factory-tested to 1500 VDC to prevent cross-channel interference and enhance system stability. Expected signal ranges include a nominal 4 to 20 mA, with an extended full signal range of 1 to 22.5 mA and overrange checking capabilities. It is likely compatible with Emerson DeltaV DCS platforms, integrating seamlessly with system controllers and I/O backplanes.

Key performance attributes may include 16-bit resolution, 0.1% accuracy over operating temperature ranges, and 0.05% repeatability for precise signal output. The card may support HART functions such as device status reporting, variable polling, and configuration adjustments via a request/response protocol, with typical HART scan times of 600-800 ms per enabled channel. Power requirements are anticipated to align with standard DCS field bus specifications, supporting 24 VDC (+/-10%) field power with per-channel maximum current output around 30-32 mA.
