KL3361 EtherCAT Terminal

The KL3361 is a single-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 resistor bridges and strain gauge sensors. It measures the bridge output voltage and reads the bridge supply voltage for ratiometric measurement, and it includes extended functions compared with the basic KL3351. The exact extended feature set (e.g., additional measurement modes, filtering, or diagnostics) must be confirmed against the current Beckhoff datasheet. 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.
