EMERSON KJ3221X1-BA1 Analog Output Module
EMERSON KJ3221X1-BA1
The KJ3221X1‑BA1 is an analog output module under Emerson’s DeltaV Series 2 Plus product line, designed for field signal output in DCS/PLC control systems. It is compatible with the 12 P series base (model: 12P2531X102), where one module can be installed per base. The module provides 8 channels of 4‑20 mA analog output (with 0‑10 V as an optional output type) and supports HART communication as well as Fieldbus H1 expansion.
