Beckhoff KL3356 original analog input

The KL3356 is a single-channel high-precision analog input terminal from the Beckhoff Bus Terminal series (KL series) for the traditional K-Bus I/O system, designed for direct connection of resistor bridges and strain gauge sensors. It measures the bridge output voltage and simultaneously reads the bridge supply voltage, performing a precise ratiometric measurement with very high resolution. It is the high-accuracy member of the KL335x resistor bridge family, suited for demanding force, torque, and weighing applications. 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.
