Product Description:

Beckhoff is a German automation company known for PC based control technology. It offers open automation systems for a wide range of industrial applications. Their solutions integrate control, I/O, motion, and automation software.

The KL3002 is a 2 channel analog input bus terminal designed for differential voltage measurement. It supports signal ranges from - 10 V to + 10 V. The voltage input is digitized with 12 bit resolution. In the 0 to 10 V range, resolution drops to 11 bits. The module offers an internal resistance greater than 200 kΩ. Conversion time of the bus terminal is approximately 2 milliseconds. It provides electrical isolation up to 500 V between the K-bus and the signal voltage. The terminal transmits data to a higher level controller in an electrically isolated manner. Input signals share a common internal ground. The device includes light emitting diodes to show data exchange status. Power is supplied to the terminal via the K-bus connection. Measurement uncertainty is less than ± 0.3 % of full scale value. The model uses differential input technology to enhance accuracy and reduce noise interference.

The KL3002 bus terminal from the KL series comes in a compact polycarbonate housing with built in signal LEDs. It measures 12 mm in width, 100 mm in height and 68 mm in depth. The terminal is installed on a 35 mm DIN rail and locks securely according to EN 60715. Mounting is facilitated using a double slot and key connection mechanism. The stripping length for wiring is between 8 and 9 mm. Its power contact supports a maximum load of 10 A. The terminal is a reliable solution for analog signal acquisition in automation systems requiring precise voltage measurement.
