The A103 totalizers provide a range of capabilities unequaled in products of similar size and cost. 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. 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.

■ Matching predetermining counter, time and rate indicators and

controllers available – look great together on a panel

■ Bidirectional models with input scale multiplier, polarity sign, decimal

point selection, and programmable reset value

■ High visibility 8-digit LCD display with backlighting capability standard

■ Long life 3 Volt lithium battery eliminates the need for external power

■ Accepts input signals from a variety of sources: Dry Contact, PNP or

NPN Sensors, Encoders

■ High speed and low speed count inputs

■ Resettable remotely or from the front panel

■ Programmable security of front panel reset button

■ Option modules provide additional functionality and added conve-

nience – fast, easy installation
