• Easy to check the output status from a long distance with changing

• Includes total and preset counter, batch counter, dual counter, twin

*1. Not supported by the H7CX-A11

@-N.

*2. The functions that can be selected depend on the model.

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 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.
