KL3142 EtherCAT Terminal

The KL3142 is a two-channel analog input terminal from the Beckhoff Bus Terminal series (KL series) for the traditional K-Bus I/O system. It measures bipolar ±10 V voltage signals with 16-bit resolution, providing finer measurement steps than the 12-bit KL3122. It is used to acquire signed voltage signals from sensors and transmitters where higher measurement resolution is 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.
