KL3102X1-BA1 | Emerson | I.S. AO 4-20 mA HART CHARM

Description

KL3102X1-BA1 is an intrinsically safe (I.S.) analog output CHARM designed for industrial control systems, featuring 4-20 mA output with HART protocol support for bidirectional signal transmission. This device offers core technical features including power reverse polarity protection, ensuring operational reliability in harsh environments. Key electrical specifications include a hazardous-side input signal of 4-20 mA with HART digital signal, open-circuit voltage ≤28V during power distribution, voltage ≥15.5V at 20 mA, and normal operating current ≤25 mA. Its output signal is also 4-20 mA with HART digital signal, supporting a maximum load resistance of 550 ohms, a response time of 2 ms to reach 90% of the final value, and an output accuracy of 0.1% F.S. It holds an explosion-proof certification of [Ex ia Ga] IIC, and is installed via a 35mm standard DIN rail with an IP20 protection rating. As part of electronic marshalling systems, it provides dedicated signal characterization and galvanic isolation for intrinsically safe applications, reducing system complexity by eliminating internal cabinet cross-wiring and optimizing I/O topology flexibility.
