05701-A-0325 霍尼韋爾分析直流輸入卡
制造商：霍尼韋爾
產(chǎn)品編號：05701-A-0325
產(chǎn)品類型：直流輸入卡
機架的直流電源可以通過直流輸入卡進入子機架。該電源可由用戶通過外部標(biāo)稱 24V 直流電源提供。直流電源通過工程卡和子機架背板連接到機架中的所有卡，并由直流輸入卡上的保險絲保護。有一個由兩部分組成的端子塊 TB1，可幫助在不斷開每條連接的電線的情況下移除卡。直流輸入卡直接與工程卡相連，為整個機架供電提供連接點。工程卡模塊的現(xiàn)場接線也在此卡上。常用電源接線,點反極性和短路保護,多電源輸入能力
在使用八塊以上 5704 催化卡的安裝中，為了防止沿機架背板的電流過大，建議控制卡通過其關(guān)聯(lián)的四路繼電器接口卡和僅用于為工程卡供電的直流輸入卡供電。
如果需要，備用電池電源也可以連接到輔助直流輸入連接。
PSU 和 AUX 連接通過二極管相互隔離。
DC 輸入卡還提供 RFI 過濾和反極性保護。

A large number of intermediate relays and time relays are used in the traditional relay control system. Due to poor contact, it is easy to fail. PLC uses software to replace a large number of intermediate relays and time relays, leaving only a small number of hardware components related to b and output. The wiring can be reduced to one tenth to one percent of the relay control system, and the faults caused by poor contact can be greatly reduced.
PLC uses a series of hardware and software anti-interference measures, which has strong anti-interference ability, and the average fault free time reaches more than tens of thousands of hours. It can be directly used in industrial production sites with strong interference. PLC big users are recognized as one of the most reliable industrial control equipment.PLC replaces a large number of intermediate relays, time relays, counters and other devices in the relay control system with software functions, which greatly reduces the workload of design, installation and wiring of the control cabinet.The ladder program of PLC can be designed by sequential control design b. This programming b is very regular and easy to master. For complex control system, if we master the correct design b, the time of designing ladder diagram is much less than that of designing relay system circuit diagram.
The user program of PLC can be simulated and debugged in the laboratory, the b signal is simulated with a small switch, and the state of the output signal can be observed through the PLC led. After the installation and wiring of the system are completed, the problems found in the field unified commissioning process can generally be solved by modifying the program, and the commissioning time of the system is much less than that of the relay system.
The failure rate of PLC is very low, and it has perfect self diagnosis and display functions. In case of failure of PLC or external b device and actuator, the cause of the failure can be easily found out according to the inbation provided by the LED or programmer on the PLC, and the failure can be quickly eliminated by replacing the module.For complex control systems, the use of PLC can reduce a large number of intermediate relays and time relays. The volume of small pic is only equivalent to the size of several relays, so the volume of switch cabinet can be reduced to the original L / 2 ~ 1 / 10.
