EW-08683-90 计时器
Gralab 451 Timer/Intervalometer; 115 VAC
Two independent, programmable memories Convenient parallel AC and logic level outputs This dual-function timer has two independent programmable memories—program one to control "on-time", the other to control "off-time". Use one memory alone for a single-cycle switching timer, or use both in tandem for a continuously recycling intervalometer. Time settings entered in memory will remain until another time is substituted—even if the unit loses power. Set time cycle or interval pattern to repeat automatically—no need to manually reset. LED display has floating decimal point and two brightness settings. Accuracy is ±0.015% of full-scale. Timer can switch resistive loads up to 1200 W as well as most inductive loads. Maximum motor load is 1/3 hp. Parallel AC and logic-level outputs let you integrate the timer into your application system. Timer switches AC power through an AC outlet and a logic-level compatible signal through an output jack. The on/off status of the output jack parallels that of the AC outlet. Optional foot switch (for remote control) is sold separately. Foot switch operates an extension of the start/reset bar.
