一般工业控制系统既包括弱电控制部分，又包括强电控制部分。为了使两者之间既保持控制信号，又要隔绝电气方面的，即实行弱电和强电隔离，是保证系统工作稳定，设备与操作人员安全的重要措施。

　　电气隔离目的之一是从电路上把干扰源和易干扰的部分隔离开来，从而达到隔离现场干扰的目的。

　　一、信号隔离

　　信号的隔离目的之一是把引进的干扰通道切断，使测控装置与现场仅保持信号，不直接发生电的。工控装置与现场信号之间常用的隔离方式有光电隔离、脉冲变压器隔离、继电器隔离和布线隔离等。

　　1.光电隔离

　　光电隔离是由光电耦合器件来完成的。其输入端配置发光源，输出端配置受光器，因而输入和输出在电气上是完全隔离的。由于光电耦合器的输入阻抗(100Ω～1kΩ)与一般干扰源的阻抗(105～106Ω)相比较小，因此分压在光电耦合器的输入端的干扰电压较小，它所能提供的电流并不大，不易使半导体二极管发光。另外光电耦合器的隔离电阻很大(约1012Ω)、隔离电容很小(约几个pF)，所以能阻止电路性耦合产生的电磁干扰，被控设备的各种干扰很难反馈到输入系统。

　　光电耦合器把输入信号与内部电路隔离开来，或者是把内部输出信号与外部电路隔离开来，如图1所示。开关量输入电路接入光电耦合器后，由于光电耦合器的隔离作用，使夹杂在输入开关量中的各种干扰脉冲都被挡在输入回路的一侧。由于光电耦合器不是将输入侧和输出侧的电信号进行直接耦合，而是以光为媒介进行耦合，具有较高的电气隔离和抗干扰能力。

　　目前，大多数光电耦合器件的隔离电压都在2.5kV以上，有些器件达到了8kV，既有高压大电流大功率光电耦合器件，又有高速高频光电耦合器件(频率高达10MHz)。常用的器件如4N25，其隔离电压为5.3kV；6N137，其隔离电压为3kV，频率在10MHz以上。

　　2.脉冲变压器隔离

　　脉冲变压器的匝数较少，而且一次绕组和二次绕组分别绕于铁氧体磁芯的两侧，这种工艺使得它的分布电容特小，仅为几个pF，所以可作为脉冲信号的隔离元件。脉冲变压器传递输入、输出脉冲信号时，不传递直流分量，PLC使用的数字量信号输入/输出的控制设备不要求传递直流分量，因而在工控系统中得到了广泛的应用。

　　图2是脉冲变压器的应用实例。电路的外部信号经RC滤波电路和双向稳压管抑制常模噪声干扰，然后输入脉冲

　　变压器的一次侧。为了防止过高的对称信号击穿电路元件，脉冲变压器的二次侧输出电压被稳压管限幅后进入测控系统内部。一般地说，脉冲变压器的信号传递频率在1kHz～1MHz之间，新型的高频脉冲变压器的传递频率可达到10MHz。

　　3.继电器隔离

　　继电器的线圈和触点没有电气上的，因此，可利用继电器的线圈接受信号，利用触点发送和输出控制信号，从而避免强电和弱电信号之间的直接接触，实现了抗干扰隔离。

　　图3是继电器输出隔离的实例示意图。在该电路中，通过继电器把低压直流与高压交流隔离开来，使高压交流侧的干扰无法进入低压直流侧。

　　4.布线隔离

　　将微弱信号电路与易产生噪声污染的电路分开布线，zui基本的要求是信号线路必须和强电控制线路、电源线路分开走线，而且相互间要保持一定的距离。配线时应区别分开交流线、直流稳压电源线、数字信号线、模拟信号线、感性负载驱动线等。配线间隔越大，配线越短，则噪声影响越小。但是，实际设备的内外空间是有限的，配线间隔不可能太大，只要能维持zui低限度的间隔距离便可。

　　附表列出了信号线和动力线之间应保持的zui小间距。如果受环境条件的限制，信号线不能与高压线和动力线等离得足够远时，就得采用诸如信号线路接电容器等各种抑制电磁感应噪声的措施。
