Product Brief:

12P2536X042, alias KJ3202X1‑BA1 and VE4002S1T2B4, is legacy Series2 high‑side discrete output module for Emerson DeltaV DCS system. It adopts high‑side positive‑side switching design with 8 output channels, opto‑isolation design effectively eliminates ground loop interference and protects system backplane from field transient surge. Each channel is equipped with independent current‑limiting and short‑circuit protection to prevent local field faults from spreading to the whole I/O rack. It receives control commands from DeltaV main controller, outputs 24VDC switching signal to control field solenoid valves, indicator lamps and motor starting equipment. Hot‑swap function supports online replacement without rack shutdown. 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。
