Recent advances in low voltage silicon germaniumand BiCMOS processes have allowed the design andproduction of very high speed amplifi ers. Because theprocesses are low voltage, most of the amplifi er designshave incorporated differential inputs and outputs to regainand maximize total output signal swing. Since many lowvoltageapplications are single-ended, the questions arise,“How can I use a differential I/O amplifi er in a single-endedapplication?” and “What are the implications of suchuse?” This Design Note addresses some of the practicalimplications and demonstrates specifi c single-endedapplications using the 3GHz gain-bandwidth LTC6406differential I/O amplifi er.

EDA9060开关量I/O 模块在电气控制柜中的典型应用—— EDA9060结合交流接触器实现远程控制EDA9060开关量I/O模块是山东力创科技自主研发的一款分布式DI/DO工控模块,主要功能特点:◎4路开关量输入,4路继电器输出。继电器两组常开2触点,两组常开常闭3触点。输出触点容量为8A 125VAC(5A 250VAC5A30VDC),由于触点容量较大,可以直接用在很多的常见电气控制电路中。输出有两种方式,一种电平式,一种脉冲式,可以灵活配置。◎标准的RS485接口,方便组网,结合GPRS DTU无线模块可以实现无线远程控制功能。◎灵活的协议,兼容研华协议,支持标准MODBUS RTU协议,方便上位机的系统组建。EDA9060在电气控制柜中有着广泛的应用,通过增加EDA9060远程控制线路,改变了原来必须依靠人工到现场启停电气线路的状况,实现无人值守,节省资源。线路改造主要通过EDA9060的继电器输出控制交流接触器,从而实现远程控制现场用电设备(如常见的工业泵)的启停。同时增加一个转换开关,将手动控制线路和EDA9060远程控制线路隔离开,以保证现场操作优先的要求,同时增强操作的可靠性。下面以交流接触器控制线路在220V电压等级以内的常见控制电路为例,简要说明其控制过程,线路容量大的情况只需要通过增加合适容量的中间继电器,扩大EDA9060的触点容量即可解决,示意图:
