Beckhoff KL3152 original analog input

The KL3152 is a two-channel analog input terminal from the Beckhoff Bus Terminal series (KL series) for the traditional K-Bus I/O system, featuring integrated diagnostics. It measures 0–20 mA or 4–20 mA current-loop signals with 16-bit resolution, providing finer measurement steps than the 12-bit KL3112, while offering diagnostic feedback on input status. It is used to acquire current-loop signals from transmitters and sensors where higher measurement resolution and fault visibility are required. Unlike EtherCAT terminals (EL series), the KL series communicates via the K-Bus and is typically used with Beckhoff Bus Couplers or Bus Terminal Controllers.
