4.2. I/O Module Functions • High Level Analog Input / HART Input Module (16pt) – The High Level Analog Input Module txhawb nqa ob theem siab analog thiab HART inputs. Analog inputs feem ntau yog 4-20mA DC rau ob qho tib si thiab HART. HART cov ntaub ntawv tuaj yeem siv rau cov xwm txheej thiab teeb tsa. HART cov ntaub ntawv, xws li cov hloov pauv theem nrab thiab theem nrab, kuj tuaj yeem siv los ua cov txheej txheem tswj kev sib txawv. Ob versions Ib qho kawg thiab txawv hom muaj. • High Level Analog Input w/o HART (16pt) – The High Level Analog Input Module txhawb cov qib siab analog inputs Analog inputs feem ntau yog 4-20mA DC rau cov khoom siv ib txwm muaj. • Analog Output/HART Output Module (16pt) – Lub Analog Output Module txhawb nqa ob tus qauv 4-20mA DC outputs thiab HART transmitter outputs. • Analog Output w/o HART (16pt) – Lub Analog Output Module txhawb nqa tus qauv 4-20mA DC outputs. • Digital Input 24 VDC (32pt) – Digital input sensing for 24V signals • Digital Input Sequence of Events (32pt) – Txais 24VDC discrete signals as discrete inputs. Cov tswv yim tuaj yeem yog lub sijhawm tagged los txhawb 1ms kev daws teeb meem Ib ntus ntawm Cov Txheej Txheem. • Digital Input Pulse Accumulation (32pt) – Txais 24VDC discrete signals as discrete inputs. Thawj 16 channel tuaj yeem tsim kho raws li Pulse accumulation los txhawb Pulse Accumulation thiab ntsuas zaus ntawm ib qho channel. Channel 17 - 32 tuaj yeem tsim kho raws li DI. • Digital Output 24 VDC (32pt) – Tam sim no sinking digital outputs. Outputs yog hluav taws xob luv-circuit tiv thaiv. • DO Relay Extension Board (32pt) – Digital output with NO or NC dry contacts. Nws tuaj yeem siv rau kev siv hluav taws xob tsawg lossis kev siv hluav taws xob siab. • Tsawg Theem Analog Input – RTD & TC (16pt) – Muab cov thermocouple (TC) thiab cov cuab yeej kub tsis kam (RTD) inputs. 4.3. Series 8 I/O Sizing Nyob rau hauv tag nrho cov configurations, lub C300 maub los thiab Series 8 I/O muab kev pab, tswj cov txheej txheem cov khoom sib txuas nyob rau hauv ib tug me me hneev taw dua uas twb muaj lawm cov neeg sib tw thiab Honeywell sib npaug cov khoom. Txhim kho Series 8 I/O modules pab txhawb rau tag nrho cov nyiaj tau los ntawm kev txuag nyiaj. IOTA qhov ntau thiab tsawg sib txawv raws li daim ntawv thov. Feem ntau, ib qho analog module muaj 16 cov ntsiab lus thiab nyob ntawm 6 nti (152mm) IOTA rau daim ntawv thov tsis rov qab thiab 12 nti (304mm) IOTA rau daim ntawv thov rov ua dua. Ib tug discrete module muaj 32 cov ntsiab lus thiab nyob rau ntawm 9-nti (228mm) IOTA rau daim ntawv thov tsis redundant thiab 12 nti (304mm) IOTA rau redundant daim ntaub ntawv. Cov ntaub ntawv tshwj xeeb ntawm qhov loj ntawm ib qho module tshwj xeeb tau piav qhia nyob rau hauv Model Number Table. 4.3.1. Series 8 Field kev sib txuas Series 8 Field kev sib txuas siv tus qauv modular connector. Lub connector modularity tso cai rau kev tshem tawm thiab ntxig ntawm cov kab hluav taws xob. Qhov no txo qis kev teeb tsa thiab kev saib xyuas cov txheej txheem thiab tuaj yeem pab hauv kev kuaj xyuas. Series 8 teb connectors txais mus txog 12 AWG / 2.5 mm2 stranded hlau.
