Counter Inrush Current (Major Models)

"---" indicates a constant current and therefore the corresponding values are omitted from the table. All the values are approximate values and should therefore only be used as a guide.

Instantaneous output when power is turned ON.
Output OFF during reset input.
H7BXIn output mode N or F, instantaneous output when power supply is turned ON and turns OFF during the reset
input. In any other mode, instantaneous output turns and then turns OFF after the one-shot time has
elapsed. In mode K-1, output turns OFF after the one-shot time for output 2 has elapsed even if output 1 is
set to be self-holding.

What Is a Time Counter?

A Time Counter counts time and displays the length of time that has been counted. Time Counters are also called Total Time Meters or Hour Meters. Hours is not the only unit available, and time can be displayed in minutes, seconds, or in some cases even days. A Time Counter is not a Timer. You set a specific time with a Timer and an electrical signal is output when that time has elapsed. With a Time Counter, you do not set a time. It simply totals the time and displays that total. If you were to define the two in terms of Timers, then a Timer would be a Preset Timer and a Timer Counter would be a Total Timer. The Time Counter, however, has historically been classified as a Counter.
