BENTLY 1900/65A-00-02-01-01-01监测器模块
PROtop具有非常好的输出过流动态范围，能可靠触发断路开关和驱动大功率设备启动和运行。在打叶复烤生产线上，PROtop提供稳定、持久和高效的直流电输出。同时生产线还要求具有持续稳定的功率裕量、长使用寿命和对过压、环境温度或振动的低敏度，这些正是魏德米勒PROtop电源所擅长的。
BENTLY 1900/65A-00-02-01-01-01监测器模块而创新的电子负载监控maxGUARD整合了以往需独立安装的等电位分配端子，形成24V DC电源分配系统，可节省高达50%的空间及20%的安装时间。maxGUARD具有模块化设计，在打叶复烤生产线上的优势展现地淋漓尽致。它在各种模块之间（馈电、负载监控和等电位分配端子）的横联件联接模式，有效地减少了所需的布线时间。● 配备认证级直流保险丝的直流和交流宽范围输入：88-375Vdc, 85-264Vac

control station and remote i/o station of each subsystem; Ethernet layer, that is, Ethernet single network communication is adopted between PLC and upper computer. The digital and analog signals of each field device in the coke removal system are connected with the remote i/o station through the control cable to realize the input and output of the signal.
The hardware of the control system adopts ab1756 series products, which not only has high reliability, high stability, operability and functional integrity, but also has convenient scalability and maintainability, and can operate continuously and reliably in the industrial environment of electromagnetic interference and vibration. When the CPU or communication of the system fails, all output modules can be set to one of the three predefined states of off, hold and safety to ensure the safety of the process system and equipment. Its operation station adopts Dell commercial computer, equipped with 10/100mbit/s Ethernet card.
