Add/Subtract
Totalizer

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 A103-001 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.

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.

Setup is quick and simple as the
two front panel keys are used to
scroll through 4 menu choices.   A
NEMA 4X front panel and noise
immunity tested to IEC 801 level 3
makes this unit suitable for harsh
environments.
