Product Description: Emerson KJ3001X1-CB1 Analog Output Module

The Emerson KJ3001X1-CB1 is a dependable analog output module used in DeltaV systems that require precise current control for field equipment. The module delivers stable 4–20 mA output signals that help operators maintain consistent control loops across complex process environments. Moreover, its isolated channels reduce electrical noise, giving technicians cleaner signals and better long-term reliability.

The module works with several Emerson MTUs, offering flexible wiring options for compact or fused terminal assemblies. In addition, the built-in HART pass-through function allows smart devices to send diagnostics directly to the DeltaV host without additional hardware. This makes integration easier for teams upgrading legacy assets or expanding their DCS architecture.

Engineers working in hazardous locations will appreciate that the module supports Zone 2 and Class I Division 2 applications. Its rugged housing withstands vibration, shock, and wide humidity ranges, therefore ensuring stable performance in demanding industrial conditions.
