Emerson KJ3221X1-BA3 DeltaV Series 2 M-Series Analog Output Module
The Emerson KJ3221X1-BA3 is an 8-channel analog output module designed for the DeltaV Series 2 M-Series distributed control system. It converts digital controller commands into 8 isolated 4-20 mA current signals to control field devices such as valve actuators, variable frequency drives, dampers, and positioners while providing bi-directional HART communication.
HART Protocol and Signal Output
The module delivers eight isolated analog channels operating on a standard 4-20 mA current loop. Built-in HART communication enables simultaneous transmission of analog control signals and digital field device data, allowing maintenance personnel to perform remote calibration, query instrument status, and manage field diagnostics through the system software.
Hardware Maintenance and System Compliance
Designed for online maintenance, the module supports hot-swapping to allow removal and replacement without interrupting power or operations on adjacent cards on the carrier. It complies with ATEX Zone 2 requirements and CE standards for operation in hazardous industrial environments, with an operating temperature range of -40 deg C to +70 deg C.
