TLP291 consists of photo transistor, optically coupled to a gallium arsenide
infrared emitting diode. TLP291 is housed in the SO4 package, very small
and thin coupler.
Since TLP291 is guaranteed wide operating temperature (Ta=-55 to 110 ˚C)
and high isolation voltage (3750Vrms), it’s suitable for high-density surface
mounting applications such as small switching power supplies and
programmable controllers.

这个是电路控制中的说法。在很多自动化设备中，电路终都需要对一些执行部件(如电机、
电磁铁)实施控制，电路对这些执行部件的控制可通过继电器、双向晶闸管、晶体管等开关器
件进行，因此对于电路的输出端来说就有了与之对应的"继电器输出、双向晶闸管输出、晶体
管输出"等类型。
