Beckhoff KL3228 original analog input

The KL3228 is an eight-channel analog input terminal from the Beckhoff Bus Terminal series (KL series) for the traditional K-Bus I/O system, designed for direct connection of resistance temperature detectors (RTDs) with high-precision measurement. It measures the resistance of PT100/PT1000 sensors and converts it to temperature values for the controller, with improved accuracy compared with the standard KL3208. It is the high-density, high-precision member of the KL32xx RTD input family. 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.
