605 型數(shù)字控制電子元件用于控制功率范圍為 40–2,000 mA 的比例電磁閥。電子元件將外部標(biāo)準(zhǔn)信號轉(zhuǎn)換為脈沖寬度調(diào)制(PWM)信號,以連續(xù)調(diào)節(jié)比例閥的開度以及流體輸出變量(例如流量)。利用 PWM 信號的占空比作為控制變量的內(nèi)部電流控制確保了輸入信號的每個(gè)值*地與有效線圈電流的特定值相關(guān)聯(lián),而不管線圈的溫度狀態(tài)如何。通過顯示屏和控制按鈕,可以輕松調(diào)整電子元件,以適應(yīng)特定的比例閥以及應(yīng)用的特定條件。為了將控制閥以及比例閥集成到更高級別的控制系統(tǒng)中,必須使用基于 CAN 的控制器型號(稱為 büS)。使用 Bürkert Communicator 軟件可以快速、輕松地進(jìn)行比例閥的參數(shù)設(shè)置和配置。 此外,büS 控制電子元件允許將截止閥集成到büS/CAN 系統(tǒng)中。通過集成的時(shí)間控制功能,截止閥可以打開或關(guān)閉一段時(shí)間。這可以用于灌裝過程中的劑量控制等應(yīng)用。8605 型可以選配一個(gè) I/O 電路板。這樣可以連接外部傳感器或開關(guān)。閥門對這些輸入信號的響應(yīng)可被配置(例如兩點(diǎn)控制)。

In order to integrate the control electronics - and thus the solenoid control
valve - into a higher-level PLC system, a CAN d version (so called büS)
is available. The parameterization and configuration of the solenoid control
valve can be done quickly and easily by the Bürkert Communicator software.
output parameter (e.g. flow rate) can be infinitely varied. An internal current
control with the duty factor of the PWM signal as valve control signal 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 buttons allow the electronics to be easily adjusted to a
particular proportional valve and to the concrete conditions of an application.
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
