These Programmable Count Down Timers feature a 4-digit, 99:59 display with 4" or 6" tall flip digits and microprocessor electronics. They are ideal for viewing elapsed time interval over a long distance. Applications include process timing, time and motion studies, worker productivity training, and sports timing. The timers may be ordered to display in Hrs:Min or Min:Sec.

Exceptional count viewing distance, even outdoors in bright sunlight, is achieved by the 4" or 6" tall fluorescent yellow, electromagnetic flip digits. A sealed surface mount case provides protection for installation in dirty or damp environments. Please see our Mechanical Section for dimensions.

A keypad mounted on the side of the housing allows presetting a time, repeating the time, and start/stop operation. The keypad also provides a DIN connector to accept optional remote accessories: a Remote Control for Start/Stop, Clear, and Repeat functions, or a Remote Keypad which duplicates all functions of the main keypad.

Options include 230 Vac or 12 Vdc power in lieu of 115 Vac power, a Sonic Alarm and a Relay Output, which actuate when times reaches 00:00.

An 18-Month Warranty is standard.
