3.For Insulation Detection绝缘检测用途

APSEMI Photo Relays are used for monitoring storage battery units for insulation deterioration. If the insulation in a unit deteriorates, a ground-fault current passes when the relay is turned ON, and a sensor detects the current. High load voltage type APSEMI Photo Relays are ideal for use with storage batteries, which carry high voltage.

使用APSEMI Photo Relays对蓄电池单元的绝缘劣化进行监控。单元内部发生绝缘劣化的情况下，置ON时将会有接地电流流过，传感器将会进行检测。由于蓄电池属于高电压，因此适合使用高耐压型APSEMI Photo Relays。

A variety of signals, with levels from millivolts (at microamperes) to tens of volts (at several hundred milliamperes), AC or DC, and even high bit-rate signals, can be superimposed on telephone lines, the heart of telecommunication networks. The switches in telecommunication circuits, which normally carry DC signals, also carry AC signals on top of the DC level when an intermittent signal (e.g. ringer signal) is being sent. APSEMI Photo Relays are capable of controlling small level (millivolts at microamperes) AC or DC signals.

通话线中从μA/mV到数百mA/数＋V、从直流到交流、高位信号等，重叠有很多信号。APSEMI Photo Relays在DC、AC下可控制μA/mV的微小信号。

7.Communications equipment通信设备
APSEMI Photo Relays can easily be connected in parallel, difficult with conventional transistor type. As a result, a variety of circuit connection are possible and power circuits can also be designed.

APSEMI Photo Relays可简单地并联，电路自由度较高，可构成功率电路。

8. Programmable controller PC端

The output circuit of a programmable controller requires various interfaces to match the load type. Recently, as the computing speed and data processing speed increase, problems may arise from noise at the input interface as well as at the output interface.
APSEMI Photo Relays are resistant to inrush current (due to phase shift) and eliminate the need for snubber circuits as long as they are operated within the ratings. Furthermore, use of APSEMI Photo Relays decreases the mounting area requirements, resulting in more compact programmable controllers.

可编程控制器的输出电路因负载种类而不同，因此备有各种接口。输入接口的干扰和输出接口的干扰都会引发故障。APSEMI Photo Relays抗瞬间值强，在额定值范围内不需要使用缓冲器。此外，安装面积较少，可实现PC的小型化。
