控制电磁阀的PLC或控制系统的输出电路
摘要：
本实用新型涉及一种控制电磁阀的PLC或控制系统的输出电路，特点是包括一组以上的输出电路及瞬态抑制二极管，每组输出电路均包括第一至第四电阻、光耦合管、普通二极管及场效应管或三极管；其中第一电阻的一端与PLC或控制系统的主板信号输出端电连接，另一端分别与第二电阻的一端及光耦合管的输入端的2脚电连接；第二电阻的另一端与光耦合管的输入端的1脚电连接；光耦合管的输出端的4脚分别与第三电阻及第四电阻的一端电连接；第三电阻的另一端接地，第四电阻的另一端与场效应管的栅极或三极管的基极电连接；场效应管的源极或三极管的发射极接地，场效应管的漏极或三极管的集电极与普通二极管的正极及电磁阀的输入端电连接，每组普通二极管的负极均与瞬态抑制二极管的负极电连接。其优点为：由于每组输出电路共用一只瞬态抑制二极管，价格便宜，降低了生产成本。
摘要（英）：

The utility model relates to a PLC of control solenoid valves or output circuits of a control system. The PLC is characterized by comprising one or more output circuits and a transient voltage suppressor. Each output circuit comprises a first resistor, a second resistor, a third resistor, a fourth resistor, an optical coupling tube, a general-purpose diode and a field-effect tube or audion, wherein one end of the first resistor is electrically connected with the main board signal output end of the PLC or control system, the other end of the first resistor is electrically connected with one end of the second resistor and the second pin of the input end of the optical coupling tube, the other end of the second resistor is electrically connected with the first pin of the input end of the optical coupling tube, the fourth pin of the output end of the optical coupling tube is electrically connected with one end of the third resistor and one end of the fourth resistor, the other end of the third resister is grounded, the other end of the fourth resistor is electrically connected with the grid of the field-effect tube or the base of the audion, the source of the field-effect tube or the emitter of the audion is grounded, and the drain of the field-effect tube or the collector of the audion is electrically connected with the positive electrode of the general-purpose diode or the input end of the corresponding solenoid valve. The negative electrode of each general-purpose diode is electrically connected with the negative electrode of the transient voltage suppressor. The PLC of the control solenoid valves or the output circuits of the control system have the advantages that because the output circuits share one transient voltage suppressor, the price is low and the production cost is lowered.
