BURKERT控制器787754是一种过程和程序调节器，带有zui多四个调节器或程序信道。装置的规格为 144 mm x 130 mm，适合尺寸为 92 mm x 92 的 DIN 控制板凹口和 170 mm 的安装深度。使用一个 27 色 5“ 彩色显示器作为指示器。操作界面可自由设计，根据个人喜好进行调整。在两个可自由配置的显示屏界面中，可根据用户需要放置文本、工艺值、背景图和图标。zui多存在四个模拟输入端和六个二进制输入端以及六个用于控制输出端或模拟输出端的插槽。为了通过一台电脑进行舒适配置，还可提供一个安装程序。标准测量值传感器的线性化已保存；可以对四个符合客户要求的线性化表格进行编程。借助于数学和逻辑模块，可以对装置进行调整，使其适合各种不同的调节和控制任务。通过两个串口 RS422/485 或 PROFIBUS-DP，可以将装置集成安装在一个数据联合中。用户可通过简单的方式加装组件（参见组块结构）。通过锁螺丝对插式端子在背面进行电气连接。
BURKERT控制器787754特点：
色彩鲜明的 27 色 5” 彩色显示器
可自由配置的显示屏界面
zui多 4 个调节器信道
对包含 1000 个节段的 50 个程序进行动态管理
BURKERT控制器787754技术参数：
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 |
