Emerson KJ3222X1‑BA1 12P2532X152 CE4003S2B1 Analog Output Module

The Emerson KJ3222X1‑BA1 with part numbers 12P2532X152 and CE4003S2B1 is an 8‑channel analog output module for Emerson DeltaV DCS control systems. It converts digital control signals into 4‑20mA analog output to drive field actuators, control valves and positioners for closed‑loop process regulation in industrial plants.

This hot‑swappable rack‑mount module supports HART communication for smart field device configuration and diagnostics. It provides channel‑level fault detection and fits standard DeltaV I/O rack slots, widely deployed in petrochemical, chemical and power‑generation DCS control cabinets.
