Veeder Root A103-000 Totalizer Technical Manual
Introduction
Within the Danaher Controls A103 family you'll find a product to meet nearly every
requirement for panel mounted control and indication. Housed in a DIN standard 36mm x
72mm case, the A103-000 meets the requirements for basic count totalization applications.
No required programming leads to plug-and-play simiplicity and minimal installation 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 low battery indicator appears on the screen to provide a warning several
weeks before the end of battery life. If two batteries are used simultaneously, the individual
expected life doubles to 10 years.
A NEMA 4X rating and a high
level of noise immunity make this
unit sutiable for harsh
environments. Several option
modules are also available that
provide added functionality and
convenience.
