Emerson KL3022X1-BA1 DeltaV AO 4–20 mA HART Terminal Block

The KL3022X1-BA1 terminal block carries analog output and HART signals for Emerson DeltaV electronic marshalling systems. This unit routes 4–20 mA commands from the controller to field valves and positioners. Engineers specify it for clean signal paths in compact marshalling cabinets.

Physical Dimensions and Weight

The KL3022X1-BA1 measures 22 mm in width and 95 mm in depth. Its housing stands 105 mm tall, which fits standard CHARM carrier slots in DeltaV cabinets. The block weighs approximately 0.1 kg, so carrier loading stays balanced during marshalling builds.

Interface and Connectivity

This block plugs into the CHARM carrier through 1 edge connector on the rear face. The KL3022X1-BA1 presents field wiring through 2 screw terminals on the front face. Consequently, technicians can land output leads without extra terminal pieces. Two LEDs report channel activity and fault status during commissioning.

Component Count and Build

Each KL3022X1-BA1 carries 1 analog output path with HART signal coupling. The assembly includes 2 screw terminals and 1 isolation barrier. Furthermore, 1 output filter circuit suppresses noise on long field cables.

Energy Storage and Power Parameters

The block draws power directly from the CHARM carrier backplane. A 0.01 F capacitor stabilizes the output reference during conversion cycles. Therefore, the KL3022X1-BA1 holds signal accuracy through brief supply dips. The design stores no long-term energy and needs no backup battery.

Key Technical Parameters

Integration Notes

The KL3022X1-BA1 slides into any free CHARM carrier slot without tools. Technicians assign channel tags through the DeltaV configuration software before startup. Additionally, the HART coupling lets engineers reach smart valve diagnostics over the same loop.
