輸入保護(hù)電路

一般模塊電源產(chǎn)品都有內(nèi)置濾波器，能滿足一般電源應(yīng)用的要求。如果需要更高要求的電源系統(tǒng)，應(yīng)增加輸入濾波網(wǎng)絡(luò)。可以采用LC或π型網(wǎng)絡(luò)，但應(yīng)注意盡量選擇較小的電感和較大的電容。
 
為了防止輸入電源瞬態(tài)高壓損壞模塊電源，建議用戶在輸入端接瞬態(tài)吸收二極管并配合保險絲使用，以確保模塊在安全的輸入電壓范圍之內(nèi)。為了降低共模噪聲，可以增加Y(Cy)電容，一般選擇幾nf高頻電容。R為保險絲，D1為保護(hù)二極管，D2為瞬態(tài)吸收二極管(P6KE系列)。

遙控開關(guān)電路

模塊電源的遙控開關(guān)操作，是通過REM端進(jìn)行的。一般控制方式有兩種：
 
(1)REM與－VIN(參考地)相連，遙控關(guān)斷，要求VREF<0.4V。REM懸空或與+VIN相連，模塊工作，要求VREM>1V。
 
(2)REM與VIN相連，遙控關(guān)斷，要求VREM<0.4V。REM與+VIN相連，模塊工作，要求VREM>1V。REM懸空，遙控關(guān)斷，即所謂“懸空關(guān)斷”(－R)。
 
如果控制要與輸入端隔離，則可以使用光電耦合器作為傳遞控制信號。

模塊組合

(1)并聯(lián)擴(kuò)容。將相同模塊輸出端并聯(lián)，可使輸出能力增強(qiáng)，但并聯(lián)模塊的輸出電壓要調(diào)整得比較*，以保證相對均流，同時避免不必要的振蕩。對有較大電流輸出的模塊，還可以仔細(xì)設(shè)計引線電阻，以達(dá)到均流效果。用這種方法并聯(lián)的模塊，不宜超過2個。同時，如果其中一塊模塊輸出有故障，整個系統(tǒng)都將不能正常工作。并聯(lián)擴(kuò)容連接電路RL為負(fù)載。
 
(2)冗余熱備份并聯(lián)。將相同的模塊輸出端通過二極管后并聯(lián)可使輸出能力增強(qiáng)，以提高電源系統(tǒng)的可靠性。原則上如果配合相應(yīng)輸出報警電路，將模塊放在可以拆卸的母線上，這樣，出現(xiàn)故障的模塊可以及時更換。用這種方法并聯(lián)的模塊，沒有量限制。D一般為肖特基二極管。
 
(3)串聯(lián)擴(kuò)容。將相同模塊輸出端串聯(lián)，可使輸出電壓倍增，功率也相應(yīng)增加，而串聯(lián)輸出端須接二極管以進(jìn)行保護(hù)。

It also interfaces with corporate communication networks.The Model P90 server supports a USB mouse or optional USB trackball, an alphanumeric keyboard, up to two annunciator keyboards, or annuciator panels, and up to four video monitors. The P90 server also supports multiple optional touchscreens. The Model P90 server has an In Xeon? processor and can be configured with up to 1.2 TB of internal hard disk storage and up to 4 GB of ECC DDR-2 SDRAM. The serial attached SCSI (SAS) supports a system disk, expansion disks, or RAID1 or RAID5 hard drive Cluster I/O 200 Series I/O See Chart below for 200 Series part #s The 200 Series Field Bus Modules are the latest generation I/A Series I/O modules. The DIN rail mounted FBM subsystem provides a reliable, high speed communications interface between the host control processor (for example the I/A Series control station) and field I/O sensors and actuators. It incorporates innovative equipment packaging, and the use of fiber optic and/or coaxial cabling between modules to allow local or remote distribution of process I/O points. The DIN rail mounted Fieldbus Modules (FBMs) are compact, high-performance distributed process I/O modules. They perform the signal conversion required to interface the electrical input signals to/from the
