Traceable® Time Switch Controller

By Control
Traceable® Time Switch Controller

An always-remember memory permits programming 14 different switchings per day, which may be allocated over four separate weekly programs for up to 196 switchings per week.

Easy to operate—the controller will turn equipment on and off in intervals as short as 1 minute or as long as 168 hours. A manual override permits equipment to be switched on or off without disturbing the program. Program and clock times are maintained for one year by two silver-oxide backup batteries in the event of an electrical outage. Brilliant, 1/2" high LCD display shows the time-of-day, day, and event number. LED light indicates the on/off status of attached equipment.

To assure accuracy an individually serial-numbered Traceable® Certificate is provided. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology). Controls equipment to 125 VAC, 50/60 Hz, 15 amps, 1850 watts with a timing accuracy of 0.01%. High-impact ABS plastic case is 2-3/4 x 6 x 1-3/4 inches. Weight is 8-1/2 ounces. Replacement battery is Cat. No. 291-1039.
