Specifications for each option **IO R** module feature follow, while specific combinations of features are listed **ZN S** in the "Models" table, below. **II C AC Power Supply:** Provides 10 - 20 VDC @ 50 mA for display backlighting **N** and/or sensor. Requires connection to 115 or 230 VAC, 50/60 Hz **G Low Voltage Input:** Allows A103 to accept 5 to 30 VAC or VDC as timing input **High Voltage Input:** Allows A103 to accept 100 to 260 Volt AC/DC as timing input **Mechanical Relay Output:** SPDT (Form C); 120/240 VAC, 30 VDC contacts ## **Compact, cost effective control by elapsed time… large display with backlighting** **All in the family - Other matching A103 series products in this catalog A103 Totalizing Counters: Section 1 A103 Preset Counters: Section 2 A103 Tachometers/Rate Indicators: Section 4** em - oe 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. - I Matching totalizing counter, time and rate indicators, and presetcounters available – look great together on a panel - I SSR relay output – selectable Interval or ON-delay operation - I High visibility 7-digit LCD display with backlighting capability standard - I Long life 3 Volt lithium battery eliminates the need for external power - I Accepts input signals from a variety of sources: Dry Contact, PNP or NPN Sensors, Encoders - I Programmable Up or Down timing - I Resettable remotely or from the front panel - I Programmable security of front panel reset button and preset entry - I Option modules provide additional functionality and added convenience – fast, easy installation - I NEMA 4/IP65 rated front panel for use in washdown environments The A103 Preset Timers are further enhanced by a series of quickattach option modules. These can provide a power supply for sensors and display backlighting, provision for high or low voltage AC or DC timing signals, and mechanical relay output. ## **SPECIFICATIONS** **Start/Stop Input:** NPN, Contact Closure; Accumulates time when connected to common; Low State: < 1.0 VDC, High State: > 2.0 VDC (28VDC max) **Security Input:** Allows access to panel reset and programming features **Remote Reset Input:** NPN or Contact Closure to common; edge sensitive **Control Output:** Isolated Photomos relay; 0.1 amp @ 30 VAC/DC, >50 Ω on resistance.
