Emerson KL3103X1-BA1 Digital Input Module for DeltaV Electronic Marshalling

The KL3103X1-BA1 digital input module captures discrete field signals for Emerson DeltaV electronic marshalling systems. This unit reads limit switches, pushbuttons, and proximity sensors across process plants. Engineers specify it for dependable input handling in compact marshalling cabinets.

Physical Dimensions and Weight

The KL3103X1-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 module weighs approximately 0.12 kg, so carrier loading stays balanced during marshalling builds.

Interface and Connectivity

This module plugs into the CHARM carrier through 1 edge connector on the rear face. The KL3103X1-BA1 presents field wiring through 2 screw terminals on the front face. Consequently, technicians can land input leads without extra terminal blocks. Two LEDs report channel activity and fault status during commissioning.

Component Count and Build

Each KL3103X1-BA1 carries 1 discrete input channel with optical isolation. The assembly includes 2 screw terminals and 1 isolation barrier. Furthermore, 1 RC filter network suppresses contact bounce on mechanical switches.

Energy Storage and Power Parameters

The module draws power directly from the CHARM carrier backplane. A 0.01 F capacitor stabilizes the input filter rail during switching events. Therefore, the KL3103X1-BA1 keeps input states steady through brief supply dips. The design stores no long-term energy and needs no backup battery.

Key Technical Parameters

Integration Notes

The KL3103X1-BA1 slides into any free CHARM carrier slot without tools. Technicians assign channel tags through the DeltaV configuration software before startup. Additionally, the RC filter keeps readings clean on long cable runs through noisy plant areas.
