SCALE

*Limited to ≤70V for CE conformance or UL approval.

**Input frequency ≤50 kHz

A specific sensitivity scale is applied according to the pulse

amplitude by setting up the DIP switch and PC Configurator

Software (model: JXCON). The scaled input voltage is then

compared to the detecting level at -2.00 through +4.00V.

With DC coupling, the scaled maximum input voltage level

voltage must be higher than and the scaled minimum input

voltage level must be lower than the detecting level so that

the pulse state is accurately detected.
