放大器是一个电子控制单元，适用于开环比例阀。控制器的输出电流与参考信号成正比，与温度变化和负载阻抗无关。比例电磁铁采用PWM供电，可以减小阀的磁滞，提高控制精度。在前面板上安装了一个可调的电位器，用于参数设置，以提高系统性能。放大器有三种型号，用于单电磁比例阀，双电磁比例阀和单电磁比例阀，具有双通道控制。每种类型的电子控制单元都有不同的大电流和开关频率(PWM)，可以根据所使用的阀门类型(PWM)进行选择。
控制电压可以直接施加到控制输入1，也可以借助电源的9v调节电压，通过外部控制值电位器施加到控制输入1
供应设备。对于这个输入，以下是有效的:9v ?1)控制值输入2为差分输入(0 ~ 10v)，带DIL开关2)，可配置电流输入(4 ~ 20ma或0 ~ 20ma)。如果控制值由具有不同参考电位的外部电子元件前馈(例如，通过PLC)，则必须使用该输入。当施加或去除控制电压时，必须小心地从输入端断开或连接两根信号电缆。

The amplifier is an electronic control unit suitable for open-loop proportional valves. The controller’s output current is proportional to the reference signal and independent of temperature changes and load impedance. Proportional electromagnet using PWM power supply, can reduce the magnetic hysteresis of the valve, improve the control accuracy. On the front panel, an adjustable potentiometer for parameter setting is installed to improve system performance. The amplifer is available in three models for single-solenoid proportional valves, dual-solenoid proportional valves, and single-solenoid proportional valves with dual-channel control. Each type of electronic control unit has different high current and switching frequency (PWM), which can be selected according to the type of valve used (PWM).
The control voltage can be applied to the control input 1 directly or via an external control value potentiometer with the help of the 9 V regulation voltage of the power
supply device. For this input, the following is valid: 9 V? 100% 1) Control value input 2 is a differential input (0 to 10 V). With DIL switch 2), it can be configured for current input (4 to 20 mA or 0 to 20 mA). This input must be used if the control value is fed forward by an external electronic component with a different reference potential (for example, via a PLC). When applying or removing the control voltage, care must be taken to disconnect or connect the two signal cables from the input.
