Product Brief:

12P3275X022, alias KJ3204X1‑BA1 and VE4002S1T2B5, is legacy Series2 high‑density high‑side discrete output module for Emerson DeltaV M‑series I/O subsystem. It provides 32‑channel 24VDC high‑side switching outputs for large‑scale discrete control applications. Each channel is equipped with independent short‑circuit and over‑current protection to prevent field faults from spreading to the system side. Opto‑isolation design improves anti‑interference performance against industrial site surge noise. It receives control commands from DeltaV main controller to drive field solenoid valves, relays and indicator lamps. Hot‑swap function supports online replacement without rack shutdown. On‑board LED gives visual feedback of power, channel group 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 terminal base compatibility before purchase. Strict ESD anti‑static protection shall be followed during installation and replacement。
