詳細(xì)介紹
BURKERT控制器787760是一種過程和程序調(diào)節(jié)器，帶有zui多四個調(diào)節(jié)器或程序信道。裝置的規(guī)格為 144 mm x 130 mm，適合尺寸為 92 mm x 92 的 DIN 控制板凹口和 170 mm 的安裝深度。使用一個 27 色 5“ 彩色顯示器作為指示器。操作界面可自由設(shè)計，根據(jù)個人喜好進(jìn)行調(diào)整。在兩個可自由配置的顯示屏界面中，可根據(jù)用戶需要放置文本、工藝值、背景圖和圖標(biāo)。zui多存在四個模擬輸入端和六個二進(jìn)制輸入端以及六個用于控制輸出端或模擬輸出端的插槽。為了通過一臺電腦進(jìn)行舒適配置，還可提供一個安裝程序。標(biāo)準(zhǔn)測量值傳感器的線性化已保存；可以對四個符合客戶要求的線性化表格進(jìn)行編程。借助于數(shù)學(xué)和邏輯模塊，可以對裝置進(jìn)行調(diào)整，使其適合各種不同的調(diào)節(jié)和控制任務(wù)。通過兩個串口 RS422/485 或 PROFIBUS-DP，可以將裝置集成安裝在一個數(shù)據(jù)聯(lián)合中。用戶可通過簡單的方式加裝組件（參見組塊結(jié)構(gòu)）。通過鎖螺絲對插式端子在背面進(jìn)行電氣連接。

BURKERT控制器787760技術(shù)參數(shù)：
Controller structure | P, I, PD, PI, PID | PID | Control loop feedback | |
Proportional band | 0 | to 9999 digits | 0 digits | Size of the proportional band |
|
|
|
| 0 means that the controller structure is out of action! |
Derivative time | 0 | to 9999 sec | 80 sec | Determines the differential component of the controller output signal |
Reset time | 0 | to 9999 sec | 350 sec | Determines the integral component of the controller output signal |
Cycle time | 0 | to 9999 sec | 20 sec | When using a switched output, the cycle time should be chosen so |
|
|
|
| that the energy fl ow to the process is quasi continuous, i.e. as con- |
|
|
|
| tinuous as is practicable without overloading the switching elements |
Contact spacing | 0 | to 999 sec | 0 digits | The spacing between the two controller contacts for double- |
|
|
|
| setpoint or modulating controllers, or proportional controllers |
|
|
|
| with an integrated actuator driver |
Switching differential | 0 | to 999 digits | 1 digits | Hysteresis for switching controllers with proportional band = 0 |
Actuator time | 5 | to 3000 sec | 60 sec | The actually utilized operating time of the regulator valve with |
|
|
|
| modulating controllers or proportional controllers with an integrated |
|
|
|
| actuator driver |
Working point | -100 | to +100% | 0% | The output level for P and PD controllers (if x = w then y = Y0) |
Output level limiting | 0 | to 100% | 100% | The maximum limit for the output level |
| -100 | to +100% | -100% | The minimum limit for the output level |
Minimum relay ON time | 0 | to 60 sec | 0 sec | Limits the frequency of switching for switched outputs |
