10. OA equipment OA设备OA equipment usually contains a sensor control unit (for temperature, speed, torque, etc.), drive unit, power supply unit, and a processing unit which controls the overall system. It is organized similarly to compact factory automation machinery. APSEMI Photo Relays have wide application in the interfaces for signals which connect the functions of these units. OA 设备有传感器控制部、驱动部、电源部和控制整个系统的运算部。其结构如同一个小型的 FA 机械。 APSEMI Photo Relays 连接到功能信号接口,发挥作用。 Operates on a 24 mW input to enable direct control of C-MOS devices. 可进行C-MOS 直接控制 Signal transfer through optical coupling achieves high resistance to noise and transients, eliminating the need for adding a snubber circuit to the output to control the load voltage. 由于通过光结合进行传达,因此抗干扰性强,抗瞬间值强,因此不需要缓冲器。 Advantages in the total cost and reliability in the control system result from the absence of AC leakage current related to the snubber circuit. 也无需担心与缓冲器相关的漏电流,提高了整体的可靠性。 1 1 .Microprocessor System I/O Board 在计算机系统I/O板中的 应用
