KL2502/KS2502 - Introduction

The KL2502/KS2502 output terminals modulate the pulse width of a binary 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 contains two channels that indicate its signal state by means of light emitting diodes. The LEDs are driven in time with the outputs and show the duty factor by their brightness.
