2.1 Introduction
KL2502 - 2-channel pulse width output terminal 24 V
DC
, switching to high potential
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 is prescribed by a 16 bit value from the automation unit.
The output stage is 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.
