Hoʻopili ʻia ka Trusted® TMR 24 Vdc Digital Output Module i 40 mau lako kahua. Hana ʻia nā hoʻāʻo diagnostic triplicated a puni ka Module me nā ana ʻana no kēia manawa, a me ka volta ma kēlā me kēia ʻāpana o ke kahawai puka i koho ʻia. Hana ʻia nā hoʻāʻo no ka paʻa a paʻa i nā hemahema. Loaʻa ka ʻae ʻana i ka hewa ma o kahi papa hana Triple Modular Redundant (TMR) i loko o ka Module no kēlā me kēia o nā kahawai puka 40. Hāʻawi ʻia ka mākaʻikaʻi laina ʻakomi o ka hāmeʻa kahua. Hiki i kēia hiʻohiʻona ke ʻike i nā hemahema o ke kaʻapuni hāmama a pōkole i ka uwea kahua a me nā lako ukana. Hāʻawi ka Module i ka hōʻike ʻana o ka Sequence of Events (SOE) me ka hoʻonā o 1 ms. Hoʻololi ka hoʻololi o ka mokuʻāina i kahi komo SOE. Hoʻoholo ʻokoʻa ʻia nā kūlana puka e ka volta a me nā ana o kēia manawa ma luna o ka Module. ʻAʻole ʻae ʻia kēia Module no ka hoʻopili pololei ʻana i nā wahi pōʻino a pono e hoʻohana pū ʻia me nā hāmeʻa Intrinsic Safety Barrier.

Nā hiʻohiʻona

• 40 Triple Modular Redundant (TMR) hua helu no ka Module. • Ka ho'āʻo pono'ī a me ka ho'āʻo pono'ī. • Nānā laina 'akomi no kēlā me kēia kiko no ka 'ike 'ana i ke kaapuni hāmama a me ka pōkole kaapuni kahua uwea a me nā hewa hoʻouka. • 2500 V impulse kū i opto/galvanic kaawale pale. • Ka pale 'akomi ma luna o kēia manawa (no kēlā me kēia kanal), 'a'ole koi 'ia nā fuse waho. • Ka hōʻike ʻana o ka Sequence of Events (SOE) me ka hoʻonā 1 ms. • Hiki ke ho'ololi hou 'ia ka Module ma ka laina me ka ho'ohana 'ana i ka Hoa ho'ola'a (e pili ana) Slot a i 'ole SmartSlot (ho'okahi kau kaawale no na Module he nui).

ʻO ke kūlana hoʻopuka o ka Panel Front Light Emitting Diodes (LEDs) no kēlā me kēia kiko e hōʻike ana i ke kūlana hoʻopuka a me nā hemahema o ka uwea kahua. • Hōʻike nā LED kūlana o ka Module Panel mua i ke olakino Module a me ke ʻano hana (Active, Standby, Educated). • TϋV Certified IEC 61508 SIL 3. • Hoʻohana ʻia nā huahana i nā pūʻulu kaʻawale o ʻewalu. He Pūʻulu Mana (PG) kēlā me kēia hui.

ʻO ka TMR 24 Vdc Digital Output Module he lālā ia o ka hui hilinaʻi o nā Module Input / Output (I/O). Hoʻokaʻawale nā ​​ʻōnaehana I/O a pau i ka hana maʻamau a me ke ʻano. Ma ka pae maʻamau, nā I/O Modules a pau i ka Inter-Module Bus (IMB) e hāʻawi i ka mana a hiki ke kamaʻilio me ka TMR Processor. Eia kekahi, loaʻa i nā Module āpau kahi pānaʻi kahua i hoʻohana ʻia e hoʻopili i nā hōʻailona kikoʻī Module i ke kahua. ʻO nā modula āpau he Triple Modular Redundant (TMR).

1.1. Hui Hoʻopau Māhele (FTU)

ʻO ka Field Termination Unit (FTU) ka ʻāpana o ka I/O Module e hoʻopili ai i nā FIU ʻekolu a pau i kahi kikowaena kahua hoʻokahi. Hāʻawi ka FTU i ka Group Fail Safe Switches a me nā ʻāpana passive e pono ai no ka hoʻomaʻamaʻa ʻana i ka hōʻailona, ​​ka pale ʻana i ka uila, a me ka kānana EMI/RFI. Ke hoʻokomo ʻia i loko o kahi Trusted Controller a Expander Chassis, pili ka mea hoʻohui kahua FTU i ka Field I/O Cable Assembly i hoʻopili ʻia ma hope o ka Chassis. Hoʻoholo ʻia ka loulou SmartSlot mai ka HIU i nā pili kahua ma o ka FTU. Hele pololei kēia mau hōʻailona i ka mea hoʻohui kahua a mālama i kahi kaʻawale mai nā hōʻailona I/O ma ka FTU. ʻO ka loulou SmartSlot ka pilina naʻauao ma waena o Active a Standby Module no ka hoʻonohonoho ʻana i ka wā o ka hoʻololi ʻana o Module.

1.2. ʻĀpana Interface Unit (FIU)

ʻO ka Field Interface Unit (FIU) ka ʻāpana o ka Module i loaʻa nā kaapuni kikoʻī e pono ai e hoʻopili i nā ʻano o nā hōʻailona I/O. Loaʻa i kēlā me kēia Module ʻekolu FIU, hoʻokahi no ka ʻāpana. No ka TMR 24 Vdc Digital Output Module, aia ka FIU i hoʻokahi pae o ka hoʻololi hoʻololi puka, a me ka sigma-delta (ΣΔ) kaapuni hoʻopuka no kēlā me kēia o nā hoʻopuka kahua 40. Hāʻawi ʻelua mau kaapuni ΣΔ ʻē aʻe i ka nānā ʻana i ka mākaʻikaʻi waho I/O lako uila.

Loaʻa i ka FIU ka mana kaʻawale mai ka HIU no ka loiloi. Hāʻawi ka FIU i ka hoʻomaʻamaʻa mana hou no nā volta hana i koi ʻia e ka circuitry FIU. Hoʻohui ka loulou serial 6.25 Mbit/sec i kēlā me kēia FIU i kekahi o nā ʻāpana HIU. Hoʻopili pū ka FIU i nā hōʻailona "hale mālama" ma luna o ka papa e kōkua i ka nānā ʻana i ka hana a me nā kūlana hana o ka Module. ʻO kēia mau hōʻailona e pili ana i nā volta hoʻolako mana, ka hoʻohana ʻana i kēia manawa, nā volta kuhikuhi ma luna o ka papa a me ka mahana o ka papa.

1.3. Pūnaehana Interface (HIU)

ʻO ka HIU kahi e komo ai i ka Inter-Module Bus (IMB) no ka Module. Hāʻawi pū ia i ka hāʻawi ʻana i ka mana a me ka mana hoʻoponopono programmable kūloko. ʻO ka HIU wale nō ka ʻāpana o ka I/O Module e hoʻopili pololei i ka IMB Backplane. He mea maʻamau ka HIU i nā ʻano I/O kūpaʻa kiʻekiʻe loa a loaʻa iā ia nā hana maʻamau e pili ana i ke ʻano a me ka laulā huahana. Loaʻa i kēlā me kēia HIU nā ʻāpana kūʻokoʻa ʻekolu, i kapa ʻia ʻo A, B, a me C. ʻO nā pilina a pau ma waena o nā ʻāpana ʻekolu e hoʻohui i kahi kaʻawale e kōkua i ka pale ʻana i ka pilina hewa ma waena o nā ʻāpana. Manaʻo ʻia kēlā me kēia ʻāpana he Fault Containment Region (FCR), no ka mea, ʻaʻohe hopena o ka hewa ma kekahi ʻāpana i ka hana o nā ʻāpana ʻē aʻe. Hāʻawi ka HIU i nā lawelawe maʻamau i nā Modules i ka ʻohana: • High Speed ​​Fault Tolerant Communications me ka TMR Processor ma o ka IMB interface. • FCR Interconnect Bus ma waena o nā ʻāpana e koho i ka ʻikepili IMB e hiki mai ana a e puʻunaue i ka ʻikepili I/O Module i ka IMB. • Hoʻokaʻawale ʻia me ka galvanically ka hoʻokaʻawale ʻana i nā ʻikepili serial i nā ʻāpana FIU. • Redundant mana kaʻana like 'elua 24 Vdc chassis lako uila a me ka mana hooponopono no ka logic mana i HIU circuitry. • ka mana i hoʻokaʻawale ʻia i nā ʻāpana FIU. • Kikowaena ikepili Serial i ka FPU no nā LED kūlana Module. • SmartSlot loulou ma waena o Active a me Standby Module no ka co-ordination i ka manawa o Module pani. • Hoʻoponopono hōʻailona kikohoʻe e hana i ka hōʻemi ʻikepili kūloko a me ka ʻike pilikino. • Nā kumuwaiwai hoʻomanaʻo kūloko no ka mālama ʻana i ka hana Module, hoʻonohonoho, a me ka ʻikepili I/O kahua. • Ka mālama hale ma luna o ka papa, nāna e nānā i nā volta kuhikuhi, ka hoʻohana ʻana i kēia manawa a me ka mahana o ka papa.
