Description

Engineered for high-speed, dynamic measurement tasks, the BECKHOFF KS3361 acts as a high-performance Bus Terminal designed for direct connection to strain gauges in full-bridge configurations. This unit processes analog bridge signals and delivers digitized measurement values to the supervisory control system via the K-bus. By integrating a rapid analog input and a dedicated trigger input, it provides precise capturing of transient mechanical loads, making it an ideal choice for precise force, pressure, and torque logging in diverse automation structures.

The KS3361 features an integrated high-speed data logger with a 32 kbyte internal memory buffer, enabling local buffering of high-frequency signal waveforms. Its pluggable wiring design level allows for rapid terminal exchange without disconnecting the field wiring, facilitating straightforward installation and minimizing system downtime during maintenance. Compatible with all standard industrial fieldbuses through Beckhoff Bus Couplers, this terminal ensures seamless integration across varied industrial communication protocols.
