Features
- Uses the latest CMOS circuitry to achieve quiescent current consumption of less than 5µA
- 6mm black character high contrast LCD display
- Bi-directional counting (7000AS model)
- Counts pulses up to 10kHz frequency
- External reset input
- CE, UL and cUL/CSA approved
The 7000/7000AS can also be configured to count electro-mechanical contact closure events using an external resistor and capacitor to eliminate contact bounce. Similarly the supply voltage can be increased using an external resistor and 3V zener diode. See instruction leaflet for details.
