Product Description:
The KL4494 Bus Terminal is a compact I/O module designed for automation systems. It integrates two analog inputs and two analog outputs in a single unit. Data conversion and communication of the model are fast and reliable.
The KL4494 bus terminal by Beckhoff digitizes voltage signals with a 12 bit resolution. It handles signals ranging from - 10 V to + 10 V. The analog input channels are single ended and have an internal resistance of over 130 kΩ. The analog output channels support loads greater than 5 kΩ. The device provides electrical isolation between the signal voltage and K-bus rated at 500 V. The conversion time is under 2 milliseconds that ensures rapid data processing. Input data is transferred as 2 data words and 2 status bytes. Output data is structured with 2 data words and 2 control bytes. Power for the model is supplied through the K-bus. The terminal typically consumes 70 mA from the K-bus. The device maintains a measuring error within ± 0.3 % of the full scale value. All channels of the model share a common ground potential that is electrically separated from the 0 V power contact. RUN LEDs indicate the current status of data communication with the Bus Coupler.
The KL4494 bus terminal uses a spring loaded system for secure connections. It is housed in a compact unit weighing approximately 55 grams. The dimensions are roughly 15 mm in width, 100 mm in height and 70 mm in depth with an aligned width of 12 mm. It can be installed in any position and is designed to mount on 35 mm rails as per EN 60715 standards. The protection class of the KL series bus terminal is IP20 that is suitable for protected electrical environments.
