As of August 8, 2016
| Function | Total Counter / Preset Counter / Timer |
|---|---|
| Preset stages | 1stages |
| Rated supply voltage | 24 VDC |
| Operating voltage range | 85% to 110% of rated supply voltage |
| Power consumption | Approx. 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. |
