A103 Preset Timer


The A103 Preset Timers are amazingly compact in size and low in cost, with a full complement of popular features such as field programmable Up or Down timing and Interval or ON-delay operation. The A103 series also includes matching indicators for count-totalizing, timing, and rate metering, as well as preset-counter 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 selfcontained system not requiring external power.
