Specifications
Ratings
*1. 1-stage preset counter and total counter functionality.
*2. Do not use the output from an inverter as the power supply.The ripple must be 20% maximum for DC power.
*3. A response of 10 kHz (minimum pulse width: 0.05 ms) is possible if the response speed is 5 kHz and the 1-stage preset counter input mode is increment,
decrement, or increment/decrement (command input).
*4. The display is lit only when the power is ON. Nothing is displayed when power is OFF.
