Emerson KL3022X1-BA1 AO 4-20mA HART CHARM

Overview

The Emerson KL3022X1-BA1 is an Analog Output CHARM module for DeltaV™ Electronic Marshalling systems. It delivers precise 4–20 mA analog signals with integrated HART® communication. The module enables both control and digital diagnostics over a single pair of wires. It suits demanding industrial environments and drives control valves, actuators, and other analog field devices reliably. Installation is simple with a keyed terminal block for secure placement into CHARM I/O cards.
