TheKL3022X1-BA1is a high-precision Analog Output (AO) Characterization Module designed for the Emerson DeltaV Electronic Marshalling platform. This module converts digital control signals from the DeltaV system into 4-20mA analog currents to drive field devices such as control valve positioners and actuators.

Common FAQ
Why is the 4A key position important?The4Amechanical keying ensures that theKL3022X1-BA1can only be inserted into a terminal slot specifically intended for Analog Output signals. This prevents the module from being accidentally plugged into a slot wired for power-intensive Discrete I/O, protecting the internal circuitry from damage.
Does this module support "Fail-Safe" states?Yes. In the event of a communication loss between the controller and the CHARM I/O card, theKL3022X1-BA1can be configured via software to hold its last value or go to a pre-defined safe state (e.g., 4mA or 0mA) to ensure process safety.
