Zowonetsa Zamalonda

The Trusted® TMR 24 Vdc Digital Output Module imalumikizana ndi zida 40 zakumunda. Kuyesa kwapatatu kumachitika mu module yonse kuphatikiza miyeso yapano, ndi magetsi pagawo lililonse la njira yovotera. Mayesero amachitidwanso kuti apitirizebe kulephera. Kulekerera zolakwika kumatheka kudzera mu kamangidwe ka Triple Modular Redundant (TMR) mkati mwa Module pa chilichonse mwa njira 40 zotulutsa. Kuwunika kwa mzere wa chipangizo chakumunda kumaperekedwa. Mbaliyi imathandizira Module kuti izindikire zolephera zotseguka komanso zazifupi pama waya am'munda ndi zida zonyamula. Moduleyo imapereka malipoti a Sequence of Events (SOE) yokhala ndi 1 ms. Kusintha kwazomwe zikuchitika kumayambitsa kulowa kwa SOE. Zomwe zimatuluka zimadziwikiratu ndi ma voliyumu ndi miyezo yapano pa bolodi la Module. Module iyi sivomerezedwa kuti ilumikizidwe mwachindunji kumadera owopsa ndipo iyenera kugwiritsidwa ntchito molumikizana ndi zida za Intrinsic Safety Barrier.

Mawonekedwe

• 40 Triple Modular Redundant (TMR) zotulutsa mfundo pa Module. • Comprehensive, zodziwikiratu diagnostics ndi kudziyesa. • Kuwunika kwa mzere wodziwikiratu pa mfundo iliyonse kuti muzindikire madera otseguka ndi mawaya amfupi a dera laling'ono ndi zolakwika za katundu. • Kuthamanga kwa 2500 V kupirira chotchinga cha opto/galvanic kudzipatula. • Kudzitchinjiriza pakali pano (pa njira), palibe ma fuse akunja ofunikira. • Kufotokozera kwa Zochitika Pang'onopang'ono (SOE) ndi 1 ms resolution. • Module ikhoza kusinthidwa kukhala yotentha pa intaneti pogwiritsa ntchito masinthidwe a Companion (oyandikana nawo) Slot kapena SmartSlot (kagawo kamodzi kagawo ka ma module ambiri).

Front Panel linanena bungwe Light Emitting Diodes (ma LED) pa mfundo iliyonse akuwonetsa momwe zimatulutsira ndi zolakwika zama waya. • Ma LED a Front Panel Module amawonetsa thanzi la module ndi magwiridwe antchito (Yogwira, Yoyimirira, Yophunzitsidwa). • TϋV Certified IEC 61508 SIL 3. • Zotuluka zimayendetsedwa m'magulu odzipatula asanu ndi atatu. Gulu lililonse lotere ndi Gulu la Mphamvu (PG).

TMR 24 Vdc Digital Output Module ndi membala wa Ma module Odalirika a Zolowetsa/Zotulutsa (I/O). Ma module onse odalirika a I/O amagawana magwiridwe antchito ndi mawonekedwe ofanana. Pamlingo wambiri, ma I/O Modules onse amalumikizana ndi Inter-Module Bus (IMB) yomwe imapereka mphamvu ndikulola kulumikizana ndi TMR processor. Kuphatikiza apo, ma Module onse ali ndi mawonekedwe am'munda omwe amagwiritsidwa ntchito kulumikizana ndi ma module apadera m'munda. Ma module onse ndi Triple Modular Redundant (TMR).

1.1.Field Termination Unit (FTU)

Field Termination Unit (FTU) ndi gawo la I/O Module lomwe limalumikiza ma FIU onse atatu ku gawo limodzi. FTU imapereka Gulu Lolephera Zosintha Zotetezedwa ndi zida zomwe zimafunikira pakuwongolera ma siginecha, chitetezo champhamvu kwambiri, komanso kusefa kwa EMI/RFI. Ikayikidwa mu Trusted Controller kapena Expander Chassis, cholumikizira cha FTU chimalumikizana ndi Field I / O Cable Assembly yomwe ili kumbuyo kwa Chassis. Ulalo wa SmartSlot umadutsa kuchokera ku HIU kupita kumalumikizidwe amunda kudzera pa FTU. Zizindikirozi zimapita mwachindunji ku cholumikizira chamunda ndikusunga kudzipatula ku ma I / O pa FTU. Ulalo wa SmartSlot ndi kulumikizana kwanzeru pakati pa Active ndi Standby Modules kuti mugwirizanitse posinthana ndi Module.

1.2.Field Interface Unit (FIU)

Field Interface Unit (FIU) ndi gawo la Module lomwe lili ndi mabwalo ofunikira kuti agwirizane ndi mitundu ina ya ma sign a I/O. Gawo lililonse lili ndi ma FIU atatu, amodzi pagawo lililonse. Pa TMR 24 Vdc Digital Output Module, FIU ili ndi gawo limodzi la mawonekedwe osinthira, ndi sigma-delta (ΣΔ) yotulutsa gawo lililonse lazotulutsa 40. Magawo awiri owonjezera a ΣΔ amapereka kuwunika kosankha kwa gawo lakunja la I/O.

FIU imalandira mphamvu zapadera kuchokera ku HIU pamalingaliro. FIU imapereka mphamvu zowonjezera zowonjezera mphamvu zamagetsi zomwe zimafunidwa ndi FIU circuitry. Ulalo wodzipatula wa 6.25 Mbit/sec serial umalumikiza FIU iliyonse kugawo limodzi la magawo a HIU. FIU imayesanso zizindikiro zingapo za "kusunga nyumba" zomwe zimathandizira kuyang'anira momwe ntchito ndi ntchito za Module zikuyendera. Zizindikirozi zikuphatikiza ma voltages amagetsi, kugwiritsa ntchito pano, ma voltages owonetsa pa board ndi kutentha kwa board.

1.3. Host Interface Unit (HIU)

HIU ndiye malo ofikira ku Inter-Module Bus (IMB) ya Module. Imaperekanso mphamvu yogawa mphamvu komanso mphamvu yopangira pulogalamu yapafupi. HIU ndiye gawo lokhalo la I/O Module lolumikizana mwachindunji ndi IMB Backplane. HIU ndiyofala kwambiri pamitundu yodalirika kwambiri ya I/O ndipo imakhala ndi ntchito zofananira ndi mtundu wazinthu. HIU iliyonse imakhala ndi magawo atatu odziyimira pawokha, omwe amadziwika kuti A, B, ndi C. Kulumikizana konse pakati pa magawo atatuwa kumaphatikizapo kudzipatula kuti ateteze kusagwirizana kulikonse pakati pa magawo. Chigawo chilichonse chimatengedwa ngati Fault Containment Region (FCR), chifukwa cholakwika pagawo limodzi sichimakhudza magwiridwe antchito a magawo ena. Bungwe la HIU limapereka ntchito zotsatirazi zodziwika kwa ma module m'banjamo: • High Speed ​​Fault Tolerant Communications ndi TMR Processor kudzera pa mawonekedwe a IMB. • FCR Interconnect Bus pakati pa magawo kuti muvotere data ya IMB yomwe ikubwera ndikugawa data yotuluka ya I/O ku IMB. • Magalasi olekanitsidwa ndi serial data mawonekedwe ku magawo a FIU. • Kugawikana kwa magetsi kwapawiri 24 Vdc chassis voltage ndi kuwongolera mphamvu kwa mphamvu zofikira ku HIU circuitry. • Mphamvu za maginito ku magawo a FIU. • Chidziwitso cha serial data ku FPU ya ma Module status LEDs. • Ulalo wa SmartSlot pakati pa Active ndi Standby Module kuti mugwirizanitse pakusintha kwa module. • Digital Signal Processing kuti muchepetse deta yanu ndikudzifufuza nokha. • Zothandizira kukumbukira kwanuko zosungira ntchito ya Module, kasinthidwe, ndi data ya gawo la I/O. • Kusamalira m'nyumba, komwe kumayang'anira ma voltages, zomwe zimagwiritsidwa ntchito panopa komanso kutentha kwa bolodi.
