Product Description

Description

The BECKHOFF KL8548 is an 8-channel analog output module designed for integration within the BECKHOFF Bus Terminal system. It functions as a specialized interface combining analog control capabilities with integrated manual operation features, allowing operators to interact directly with the automation system. The device features eight analog outputs providing a 0 to 10 V signal range, alongside eight potentiometer input channels for manual reference setting.

As part of the K-bus connected terminal family, the KL8548 is powered via a 24 V DC connection and communicates state information to the higher-level PLC. The module incorporates hardware switches and potentiometers whose positions can be read directly by the control system, enabling seamless switching between automated and manual operating modes. Analog values are visually represented via onboard bar chart LED displays to assist with diagnostic and monitoring tasks.
