Product Description:
The model KL3444 is a 4 Channel Analog Input Bus Terminal designed for 0 to 20 mA signals. It converts input currents into 12 bit digital signals for transmission. The module is electrically isolated and designed for higher level automation systems. It uses a two wire configuration and shares a common ground.
The KL3444 bus terminal supports a conversion time of approximately 2 ms per channel. Each input of the model operates in a single ended mode with an internal resistance of less than 85 ohms. The power supply for the terminal is provided through the K bus. It is capable of withstanding a surge voltage of 30 V DC. The electrical isolation is rated at 500 V between the K bus and signal voltage. The input signal current ranges from 0 to 20 mA and the module features a 12 bit resolution for precise data acquisition. Measurement uncertainty remains within ± 0.3 % of the full scale value. Typical current consumption from the K bus is around 85 mA. The bit width in the process image is 4 x 16 bit data with optional 4 x 8 bit control/status information. The model transmits data reliably via the K bus to the controller. The four input channels share a unified reference ground that supports efficient space saving installations.
The Beckhoff KL3444 bus terminal includes LEDs that display the status of data exchange, overloads or wire breakages. Overload detection protects the system and ensures stable operation. The KL series bus terminal meets EMC standards according to EN 61000-6-2 and EN 61000-6-4 for immunity and emissions. The terminal supports operation in environments with 95 % relative humidity without condensation. It conforms to vibration and shock resistance standards EN 60068-2-6 and EN 60068-2-27.
