The Beckhoff KL2535 Bus Terminal is a sophisticated digital output module designed to control output currents through pulse width modulation of the supply voltage. This terminal is equipped with two channels, each capable of handling currents from 0 to ±1 A, and operates on a 24 V DC power supply with a permissible range of -15% to +20%. It is specifically engineered to manage inductive loads greater than 1 mH, such as valves and coils, ensuring reliable performance in a variety of industrial applications.
Each channel of the KL2535 is safeguarded against overload and short-circuit conditions, providing a robust solution for demanding environments. The terminal operates with a PWM clock frequency of 36 kHz, allowing for precise control over the duty cycle. The unit's design includes galvanic isolation from the K-bus, enhancing the safety and integrity of the system.
For ease of use and quick diagnostics, the KL2535 features light emitting diodes that indicate the signal state, simplifying the identification of load and wiring faults on-site. This functionality, combined with its technical capabilities, makes the KL2535 an essential component for automation systems requiring precise and durable current control.
