Description
KJ3221X1-BK1 is an Emerson DeltaV S-series eight-channel 4-20 mA HART analog output card. The card uses A4 terminal-block keying and is designed for 24 VDC field-powered output loops.

It converts DeltaV control commands into eight analog current outputs for compatible field devices, while HART capability supports digital communication on the same 4-20 mA loops. Typical control duties include modulating final control elements and other HART-enabled analog output equipment.

The card requires 12 VDC at 150 mA from the LocalBus and 24 VDC at 300 mA from bussed field power. Confirm the A4-keyed terminal block, loop load, field power, and channel wiring before commissioning.
