Product Description:

The KL8001-0000 is an analog input module produced by Beckhoff within the KL Analog Input Modules series. It is installed on a Bus Coupler rail to capture electrical measurements from up to ten contactor-fed branches and forward those values to the higher-level controller over the K-bus. In industrial automation, the unit is used for onboard power monitoring, enabling PLC logic to react to load changes, detect faults, and record consumption profiles without separate transducers.

The module’s power path can conduct up to 25 A, letting it handle sizable motor or heater feeders before the measurement circuit saturates. Galvanic separation between the mains terminals and the internal communication bus is rated at 6000 V, which protects the control electronics from line disturbances. During continuous sampling, the device achieves a current accuracy of 0.15 Arms; combined with a voltage accuracy of 2 Vrms, this supports meaningful phase power calculations. The process image contribution is 96 bits I/O, so the controller receives compact status, diagnostic, and value data every scan. Two ten-pin flat plug sockets form the K-bus connection, simplifying module stacking without extra wiring, and the measuring voltage is limited to 500 V.

When abnormal conditions occur, the power stage endures fault currents up to 5000 A, allowing upstream protection devices time to trip before the PCB traces fail. The copper path exhibits a resistance of < 1 mΩ, minimizing thermal rise and measurement drop across the shunt. The housing is rated IP20, which restricts finger access and the entry of foreign objects in typical cabinet environments. For consumption logging, the energy channel resolves increments down to 1 kWh, and the power channel maintains a nominal accuracy of 5 W; together, these figures support load profiling and long-term energy tracking without external meters.
