REXROTH放大器RA系列特点
模拟放大器最多可激活两个比例电磁阀。规定的控制电压在放大器中作为输入变量进行处理。模拟放大器提供调节电流作为输出变量，以驱动比例电磁阀。
比例螺线管的放大器输出通过一个死区来激活。输入端最大设定点电压的5％，即最小输出电流被施加。可以使用微调电位器分别为两个比例输出分别调整此最小输出电流的水平。如果输入上的设定值电压增加，则每个比例电磁阀的输出电流都会线性增加。
最大输出电流也可以使用微调电位器分别调节。输出曲线的斜率受此影响。
模拟放大器包含时间斜坡功能，可用于调节输出电流可以匹配修改后的设定值的时间段。斜坡时间调整范围从100ms扩展到10s。可以使用微调电位器为每个螺线管调节时间斜坡功能。
The analog amplifier activates up to two proportional solenoids. The specified control voltage is processed in the amplifier as an input variable. The analog amplifier provides a regulated electric current as an output variable for actuation of proportional solenoids.
Amplifier outputs for proportional solenoids are activated through a deadband of approx. 5% of the maximum setpoint voltage at the input, i.e. the minimum output current is applied. The level of this minimum output current can be adjusted separately for both proportional outputs using a trimming potentiometer. If the setpoint voltage at the input is increased, the output current for each respective proportional solenoid increases linearly.
The maximum output current can also be separately adjusted using a trimming potentiometer for the outputs. The gradient of the output curve is influenced by this.
The analog amplifier contains time ramp functions which can be used to adjust the period in which the output current can be adapted to match a modified setpoint. The ramp time adjustment range extends from 100 ms to 10 s. The time ramp functions can be adjusted using trimming potentiometers for each solenoid.
