Emerson KL3021X1-BA1 CHARM Analog Input Card for DeltaV Systems

The KL3021X1-BA1 CHARM analog input card captures process measurement signals for Emerson DeltaV electronic marshalling systems. This unit reads 4–20 mA transmitters and voltage sources across plant field wiring. Engineers specify it for accurate data acquisition in compact marshalling cabinets.

Physical Dimensions and Weight

The KL3021X1-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 card weighs approximately 0.12 kg, so carrier loading stays balanced during marshalling builds.

Interface and Connectivity

This card plugs into the CHARM carrier through 1 edge connector on the rear face. The KL3021X1-BA1 presents field wiring through 2 screw terminals on the front face. Consequently, technicians can land transmitter leads without extra terminal blocks. Two LEDs report channel activity and fault status during commissioning.

Component Count and Build

Each KL3021X1-BA1 carries 1 analog input channel with 16-bit resolution. The assembly includes 2 screw terminals and 1 isolation barrier. Furthermore, 1 input filter circuit suppresses noise on long field cables.

Energy Storage and Power Parameters

The card draws power directly from the CHARM carrier backplane. A 0.01 F capacitor stabilizes the measurement rail during conversion cycles. Therefore, the KL3021X1-BA1 holds reading accuracy through brief supply dips. The design stores no long-term energy and needs no backup battery.

Key Technical Parameters

Integration Notes

The KL3021X1-BA1 slides into any free CHARM carrier slot without tools. Technicians assign channel tags through the DeltaV configuration software before startup. Additionally, the input filter keeps readings stable on long cable runs through noisy plant areas.
