Product Description:

The Beckhoff KL1512 Bus Terminal is a compact 2 channel up/down counter for industrial automation. It is designed for counting tasks with up to 1 kHz frequency. The device isolates counting signals and communicates with a higher level controller. Each input channel is LED indicated for signal state monitoring.

The KL1512 bus terminal supports two independent counters and handles up or down counting. It operates with a nominal voltage of 24 V DC and tolerates – 15 % to + 20 % fluctuation. It conforms to EN 61131-2 standards with defined “0” and “1” input signal voltages. A “0” signal is between -3 to +5 V while a “1” signal ranges from 15 to 30 V. The terminal supports counting frequencies of up to 1 kHz that is suitable for applications like flow meter pulse counting. It has a 16 bit counter depth for sufficient counting range. The device uses a typical input current of 5 mA and draws about 50 mA from the K-bus. The power contacts only supply the load and are not used by the terminal itself. Configuration of the terminal is managed through a Bus Coupler or directly via a controller. The device enables counter reset or preset using register settings. Its compact housing includes LEDs for input status indication.

The KL1512 bus terminal is housed in polycarbonate material with durable construction. It weighs approximately 50 grams and is designed for easy DIN rail mounting (35 mm) conforming to EN 60715. The housing dimensions of the KL series bus terminal are 12 mm wide, 100 mm high and 68 mm deep. For convenient installation, it uses a double slot and key connection system for side by side module mounting.
