Beckhoff Automation kl2502

The KL2502 output terminal modulates the pulse width of a binary 24 V DC signal and outputs it electrically isolated from the K-bus. The mark/space ratio is prescribed by a 16 bit value from the automation device. The output stage is protected against overload and short-circuit. The Bus Terminal has two channels, whose signal state is displayed by light emitting diodes. The LEDs are driven in time with the outputs, and show the duty factor by their brightness. In addition to the KL2502 there is a 5 V DC variant (KL2502-3020) with a PWM clock frequency of up to 30 kHz.
