Beckhoff KL3162 Bus Terminal analog input

The KL3162 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 bipolar ±10 V voltage signals with 16-bit resolution, providing finer measurement steps than the 12-bit KL3122, while offering diagnostic feedback on input status. It is used to acquire signed voltage signals from sensors and transmitters 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.
