Product Brief:

12P2531X122, alias KJ3221X1‑BA1 and VE4005S2B1, is legacy HART analog output module for Emerson DeltaV DCS system. It outputs standard 4‑20mA control signals to regulate field control valves, meanwhile integrates HART modem to realize bidirectional digital communication with HART smart field devices. Users can remotely configure, calibrate and diagnose smart valve positioners through DCS system. Module exchanges control commands and device status data with DeltaV main controller via rack backplane bus. Each channel is equipped with short‑circuit protection function. On‑board LED gives visual feedback of power, channel running and fault conditions. This is EOL discontinued spare part,widely used for maintenance and renovation of petrochemical and thermal power plant DeltaV DCS equipment. Please confirm hardware revision and rack compatibility before purchase. Strict ESD anti‑static protection shall be followed during installation and replacement。
