Beckhoff KL2502

Beckhoff KL2502 Output Terminal

The KL2502 output terminal modulates the pulse width of a binary signal, and outputs it electrically isolated from the K-bus. The mark/space ratio prescribed by a 16 bit value from the automation unit. The output stage protected against overload and short-circuit. The Bus Terminal contains two channels that indicate their signal state by means of light emitting diodes. The LEDs are driven in time with the outputs and show the mark/space ratio by their brightness.
