Product Description:

The KL3464 Analog Input Bus Terminal is designed to measure voltage signals from 0 to 10 V. It digitizes the input with a 12 bit resolution and transmits data electrically isolated. The unit supports four single ended input channels and connects to automation systems via the K-bus.

The KL3464 bus terminal offers a signal voltage range of 0 to 10 V and uses single ended input technology. All four inputs share a common ground reference and are implemented as 2-wire versions. The model ensures minimal loading on signal sources with an internal resistance of more than 130 kΩ. The conversion time per channel is approximately 2 milliseconds that allows for rapid signal acquisition. It maintains high accuracy with a measurement uncertainty of less than ± 0.3 % of the full scale value. Each channel is electrically isolated from the K-bus with an isolation voltage of 500 V. The voltage inputs of the terminal are digitized to a 12 bit resolution and provide 4096 discrete levels for precise measurement. Power is supplied via the K-bus that eliminates the need for separate wiring. Data exchange with the bus coupler is visually indicated by integrated LEDs on the housing. These LEDs aid in diagnostics and operational monitoring.

The Beckhoff KL3464 bus terminal comes in a compact polycarbonate housing with signal LEDs for clear status feedback. It weighs approximately 75 grams. The dimensions of the unit are 12 mm in width, 100 mm in height and 68 mm in depth. The KL series bus terminal mounts on a 35 mm DIN rail and complies with EN 60715 standards with a locking mechanism for secure installation. The terminal’s design enables straightforward integration into standard control cabinets.
