Emerson KJ3204X1‑BA1 12P3275X032 VE4002S1T2B5 Discrete Output Module with KJ4001X1‑CJ1 Terminal Block

The KJ3204X1‑BA1 (12P3275X032, VE4002S1T2B5) is a high‑density discrete output module for Emerson DeltaV DCS systems, paired with KJ4001X1‑CJ1 matching terminal block. It receives control logic commands from DeltaV controller and outputs 24VDC high‑side switching signals to drive field solenoid valves, relays and auxiliary actuators.

This compact series‑2 module supports channel‑level short‑circuit protection and comprehensive fault diagnostics. Combined with KJ4001X1‑CJ1 field terminal assembly, it provides reliable field‑wiring interface, suitable for long‑term continuous operation in petrochemical, power and chemical plant DCS control cabinets.
