6n137多少钱，光耦p521工作电压是多少伏

1，光耦p521工作电压是多少伏

光耦p521工作电压是1.2V，工作电流是10mA。2个具有相同非线性传输特性的光电耦合器，T1和T2，以及2个射极跟随器A1和A2组成。如果T1和T2是同型号同批次的光电耦合器。可以认为他们的非线性传输特性是完全一致的，即K1(I1)=K2(I1），则放大器的电压增益G=Uo/U1=I3R3/I2R2=(R3/R2)[K1(I1)/K2(I1)]=R3/R2。由此可见，利用T1和T2电流传输特性的对称性，利用反馈原理，可以很好的补偿他们原来的非线性。扩展资料：当采用光耦隔离数字信号进行控制系统设计时，光电耦合器的传输特性，即传输速度，往往成为系统最大数据传输速率的决定因素。在许多总线式结构的工业测控系统中，为了防止各模块之间的相互干扰，同时不降低通讯波特率，不得不采用高速光耦来实现模块之间的相互隔离。常用的高速光耦有6N135/6N136，6N137/6N138。参考资料来源：百度百科-光耦

2，一般光耦的输入电阻是多少驱动电流多大

1，驱动电流一般在2~20mA2，对普通光耦来说，一般不提输入电阻。3，因为光耦的输入端实际上就是一个发光二极管，当给此二极管加上正向3V~24V的直流电压后（当然千万不能忘了串入一只合适的限流电阻），输出端的导通电阻就会从无穷大变到只有几十欧姆。可以这么说，输入端的驱动电流决定输出端的导通电阻。但一般当驱动电流大于5mA后输出端的导通电阻基本上已经达到饱和，所以一般都是根据不同的驱动电压通过调整限流电阻的阻值将驱动电流控制在5mA左右。4，普通光耦输出端的带负载能力一般在100mA左右。光耦合器（opticalcoupler，英文缩写为OC）亦称光电隔离器或光电耦合器，简称光耦。它是以光为媒介来传输电信号的器件，通常把发光器（红外线发光二极管LED）与受光器（光敏半导体管）封装在同一管壳内。当输入端加电信号时发光器发出光线，受光器接受光线之后就产生光电流，从输出端流出，从而实现了“电—光—电”转换。以光为媒介把输入端信号耦合到输出端的光电耦合器，由于它具有体积小、寿命长、无触点，抗干扰能力强，输出和输入之间绝缘，单向传输信号等优点，在数字电路上获得广泛的应用。
