DESCRIPCIÓN

The A103-001 is an ideal choice for advanced count totalization applications. An input scale factor allows input pulses to be displayed as meaningful engineering units, and dual input channels enable add/subtract counting. In addition to the totalizing models shown here, the A103 series also includes matching indicators for timing and rate/speed metering and models with a preset output for control by count or time. The 8 digit supertwist LCD display provides easy viewing at a glance. For conditions where ambient light is poor, the display can be backlit by connecting an external DC (10-28 Volt) power supply. A single unit can accept NPN & dry contact inputs for low speed (30Hz) counting and PNP or square wave signals for high speed applications up to 10 kHz. Powered by either one or two replaceable 3V Lithium batteries, this unique design allows for a new battery to be installed before removing the old one, thereby retaining count total and program data. A NEMA 4X front panel and noise immunity tested to IEC 801 level 3 makes this unit suitable for harsh environments.
