(

BINARY OUTPUT

11–14). Unlike regular relay outputs, 

BINARY OUTPUT

11–14 are bounce-free 

binary outputs and have a minimal reaction time.

In addition, 2 high-frequency counter inputs for up to 100 kHz are available for the testing of energy 
meters. They are described in section 4.5.2 "Counter inputs 100 kHz (low level)" on page 32.
