詳細介紹
BURKERT控制器787704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。操作界面可自由設計，根據(jù)個人喜好進行調(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。zui多存在四個模擬輸入端和六個二進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行舒適配置，還可提供一個安裝程序。標準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行編程。借助于數(shù)學和邏輯模塊，可以對裝置進行調(diào)整，使其適合各種不同的調(diào)節(jié)和控制任務。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（參見組塊結構）。通過鎖螺絲對插式端子在背面進行電氣連接。

BURKERT控制器787704技術參數(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 |
