  • Ratings/Characteristics
FunctionTotal Counter / Preset Counter / Timer
Preset stages1stages
Rated supply voltage24 VDC
Operating voltage range85% to 110% of rated supply voltage
Power consumptionApprox. 1.5 W (at maximum DC load)
Counter (Count range)-999~9999
Counter (Max. counting speed)30 Hz/5 kHz (switching) (Minimum counting input signal width: 16.7 ms (ON/OFF ratio: 1:1)/0.1 ms (ON/OFF ratio: 1:1))
The figures given for maximum counting speed are for incrementing or decrementing operation with a prescale value of x1. If prescaling is used and 5 kHz is set, the maximum counting speed will be reduced to about half. The maximum counting speed will also be reduced to about half when the up/down mode is selected.
