Features:
- Provides eight 4–20 mA HART analog output channels in the DeltaV M-Series form factor.
- Optically isolates each channel from the system and applies a 1500 VDC factory isolation test.
- Supports simplex or redundant I/O architecture with the appropriate Series 2 terminal hardware.
The current ordering configuration is KJ3221X1-BA3, the Series 2 M-Series eight-channel HART analog output card.
It converts DeltaV control commands into field current for compatible valve positioners, actuators, and other intelligent analog devices while retaining HART access.
Before commissioning, confirm DeltaV v10.3.1 or later, the A4 terminal key, loop loading, field power, redundancy design, and hazardous-area approval.
Availability is subject to Apter Power inventory and sourcing confirmation.

- Modulates control valves, positioners, and other 4–20 mA final control elements in continuous process loops.
- Supports intelligent field-device integration in chemical, oil and gas, water, power, and general process-control systems.
- Fits critical-loop designs that use the supported M-Series redundant terminal-block architecture.
- Provides HART pass-through for compatible intelligent instruments and AMS Device Manager access.
- Makes HART device variables and status available to configured DeltaV control functions.
- Communicates through the M-Series I/O interface and controller architecture rather than as a standalone network device.
- Operates across the documented ambient temperature range of −40 to +70°C.
- Supports 5 to 95% relative humidity when the atmosphere remains non-condensing.
- Uses conformal coating for ISA-S71.04-1985 Class G3 airborne-contaminant conditions.
- Carries the II 3G Ex ec [ic] IIC Gc marking under the documented ATEX configuration.
- Includes IECEx and UKEX component certifications for the identified hazardous-area version.
- Is evaluated for listed Class I Division 2 and Class I Zone 2 installations under applicable FM approvals.
