Description
The A103 Preset Counters are amazingly compact in size and low in cost, with a full complement of popular features. In addition to the preset counter models shown here, the A103 series also includes matching indicators for count-totalizing, timing, and rate/speed metering, as well as preset-timer models. All are in a uniform 36 x 72 millimeters bezel size package, enhancing your control panel with a family of devices that look and program alike. A supertwist LCD display with thick 12mm (.47”) high digits allows for easy viewing at a glance and feature display-backlight capability by simply connecting an external 12VDC supply. Powered by an internal 3 volt battery, the A103’s unique design has two battery slots; this allows battery changeover without loss of memory. Numerous types of inputs can be accepted giving you a totally self-contained system not requiring external power.
