BENTLY 1900/65A-00-02-01-01-01監測器模塊
PROtop具有非常好的輸出過(guò)流動(dòng)態(tài)范圍，能可靠觸發(fā)斷路開(kāi)關(guān)和驅動(dòng)大功率設備啟動(dòng)和運行。在打葉復烤生產(chǎn)線(xiàn)上，PROtop提供穩定、持久和高效的直流電輸出。同時(shí)生產(chǎn)線(xiàn)還要求具有持續穩定的功率裕量、長(cháng)使用壽命和對過(guò)壓、環(huán)境溫度或振動(dòng)的低敏度，這些正是魏德米勒PROtop電源所擅長(cháng)的。
BENTLY 1900/65A-00-02-01-01-01監測器模塊而創(chuàng )新的電子負載監控maxGUARD整合了以往需獨立安裝的等電位分配端子，形成24V DC電源分配系統，可節省高達50%的空間及20%的安裝時(shí)間。maxGUARD具有模塊化設計，在打葉復烤生產(chǎn)線(xiàn)上的優(yōu)勢展現地淋漓盡致。它在各種模塊之間（饋電、負載監控和等電位分配端子）的橫聯(lián)件聯(lián)接模式，有效地減少了所需的布線(xiàn)時(shí)間?！?配備認證級直流保險絲的直流和交流寬范圍輸入：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.
