Product Description:
The KL1512 is a Beckhoff input terminal that belongs to the KL Analog Input Modules series and is designed for direct installation on a DIN rail inside decentralized control cabinets. By offering two independent counting channels, the module transfers incremental position or event data to a fieldbus controller, allowing motion-related and production-rate feedback to be processed in industrial automation systems. Data are delivered to the controller as a 16-bit unsigned integer, and the overall process image occupies two 16-bit value words plus two 8-bit status bytes, providing deterministic access to live counts and diagnostic flags.
The first channel has a counter depth of 16 bits, so every up or down count is represented by 65,536 discrete states inside the process image. Each input accepts pulses up to 1 kHz, permitting reliable tracking of moderate-speed encoders or sensor edges. The terminal draws only 5 mA from each field device, and its power stage uses a rated load supply of 24 V DC. These values limit heat dissipation while matching common control-voltage buses. The enclosure has an IP20 rating, providing finger-safe protection when the terminal is installed in a cabinet that remains closed during operation.
Internal logic receives backplane power through the K-bus at 50 mA, simplifying system current budgeting when multiple terminals share the same segment. The housing snaps onto a 35 mm mounting rail, and the electronics tolerate any installation position without derating. Pulse recognition is synchronized to the input’s rising edge, ensuring consistent sampling when proximity switches or photoelectric sensors change state. The module provides two up or down counter inputs, allowing each channel to count pulse sequences independently. The circuitry follows EN 61131-2 Type 1 signal levels for direct compatibility with standard PLC sensors. This arrangement allows the terminal to receive commonly used industrial sensor signals without requiring separate signal conversion hardware.
