burkert00178355 宝德8605 ：数字控制电子学，8605型，用于控制功率范围内的比例电磁控制阀，从40 - 2000 mA。电子器件将一个外部标准信号转换成脉冲宽度调制(PWM)信号，即比例阀的开启，因此流体输出参数(例如流量)可以无限变化。一个内部电流控制与PWM信号的负荷因数作为操纵变量，确保输入信号的每一个值，不管线圈的热条件如何，都明确地分配了有效线圈电流的给定值。显示器和操作键允许电子设备很容易地适应特定比例阀和应用程序的具体情况。

The digital control electronics, Type 8605, serves to operate proportional solenoid control valves in the power range from 40 - 2000 mA. The electronics converts an external standard signal into a pulse-width modulated (PWM) signal with which the opening of the proportional valve and hence a fluidic output parameter (e.g. flow rate) can be infiniy varied. An internal current control with the duty factor of the PWM signal as manipulated variable ensures that every value of the input signal, irrespective of the thermal condition of the coil, is unambiguously assigned a given value of the effective coil current. A display and operating keys allow the electronics to be easily adapted to a particular proportional valve and to the concrete conditions of an application.
