Mike Krzyzewski is really a famous coach of Dream Team. She has coached north america men's basketball team for some time, that's clinched numerous medals for his country. Following Londonfl jerseys supplyn Olympic was over, Krzyzewski told The Associated Press that this game will be his final one as national coach, a job he's held for seven years. He had left open the possibility of swomen nfl jerseystaying with the team beyond the London Games, when practice on Saturday said these will be his last Olympics.When asked if he was sure, Krzyzewski didn't hesitate before again saying, "yecheap nfl jerseys wholesales," this will be his last game "If we could win it, then it might be three major championships in a row, i always do not know when that has been done because we haven't usually won http://govoriotkrito.bg/libs/nflcn08.htmthe globe championships," Krzyzewski said. "It becomes an enormous thing for the program." Whatever, he's an awesome coach. His achievement are going to be remembered by the country.cheap nfl jerseys

主要功能

(1)通电限时继电器,双设定Tno、Tnc(Tno为限时吸合时间,Tnc为限时时间),一只继电器能替代两只继电器用,高两位BCD拔码为限时释放预置时间,低两位BCD拔码为限时预置吸合时间,LED相应显示当前限时时间段,可选做倒延时模式。
(2)既可往复循环限时工作,也可单次限时工作。
(3)智能提示功能:用户限时值为全0时LED显示”Erro”,提示预置出错;在复位或单次限时时间结束后LED显示”no”(当前转换电器是吸收状态)或”nc”(当前转换继电器是释放状态)。
(4)采用高性能专用微控芯片,底部暂停、复位信号采用光电耦隔离输入,提高抗干扰能力。
(5)高精度晶体振荡器作为系统时钟源,时间精度高达0.05%。
(6)八种限时倍率,任意设置继电器限时吸合、释放时间、时间范围宽(0.01Sec~990Hr)。
(7)DIN (48mm×48mm)标准面板尺寸,标准8针接口,可方便与底座配套使用。
(8)工作电源适用范围宽,85~265VAC/DC自由输入。
