7111 Bi-directional totalising Counter. 7111QUAD Totalising counter with quadrature inputs. 7111HV Bi-directional totalising counter with high voltage inputs. 7111 | 7111QUAD | 7111HV The new 7111 series counter is feature packed and with a price performance ratio unrivalled, suitable for thousands of applications. Features • Use of the latest CMOS circuitry achieves an expected battery life of 10 years. • Connection using built in screw terminals (on all models). • 9mm black high contrast LCD display. • Backlight (externally powered) 5VDC. • Counting up to 10kHz. (7111) • 7111QUAD version quadrature signal compatible. This permits add / subtract counting in step with forward / reverse motion without count loss or gaining spurious counts. • 7111HV permits triggering from any voltage between 10-240VAC or 5-110VDC ±10%. • Contact closure/open collector low speed count input with integral de-bounce circuitry (7111 model). • Choice of mounting available, front panel with supplied bezel or rear mounting clip. • Front panel can be sealed to IP65. • Installation is simplified - all models have screw connections on rear for quick and simple connection. • UL and cUL pending.
