Chotchinga chitetezo chodzipatula cha analog input chimapereka mphamvu zodzipatula kwa ma transmitter awiri ndi atatu a waya m'malo oopsa. Chizindikiro cha 4~20mA chopangidwa ndi transmitter kapena gwero lamagetsi chimatumizidwa kuchokera kumalo oopsa kupita kumalo otetezeka, motero chimayendetsa katundu m'malo otetezeka. Kwa ma transmitter awiri kapena atatu a waya kapena zizindikiro zamagetsi, chotchinga ichi chachitetezo chimathandizira kulumikizana kwa mbali ziwiri kwa chizindikiro cha digito cha Hart chomwe chili pamwamba pa chizindikiro cha 4~20mA ndipo chili ndi ntchito ya alamu yosweka ya waya. Chogulitsachi chimafuna magetsi odziyimira pawokha, okhala ndi magetsi odzipatula, malo olowera, ndi otulutsa.

Mphamvu yoperekera	20~35V DC, Kugwiritsa ntchito mphamvu: ≤130mA (magetsi a 24V, kutulutsa kwa 20mA)
Voteji yogawa ma transmitter	Voliyumu ya dera lotseguka ndi ≤28V, ndipo voliyumu yotulutsa ndi ≥15.5V pamene dera lili 20mA.
Chizindikiro cholowera	chotumizira cha waya ziwiri kapena zitatu kapena chizindikiro cha gwero lamakono (HART)

Zipangizo zogwiritsidwa ntchito kumunda	Chotumizira cha waya ziwiri, chotumizira cha waya zitatu komanso chizindikiro chamagetsi, ichi ndi choyenera ABB, Fisher, Rosemount, Honeywell, komanso 3351, EJA, SIEMENS ndi zinthu zina zomwe zili ndi ukadaulo wochokera kunja.
Magawo a kutentha	Kutentha kogwira ntchito: -20℃~+60℃, kutentha kosungirako:-40℃~+80℃
Chinyezi chocheperako	10% ~ 95% RH palibe kuzizira
Mphamvu yotetezera kutentha	Pakati pa mbali yotetezeka mkati ndi mbali yotetezeka mkati (≥3000VAC/min); pakati pa magetsi ndi mbali yotetezeka mkati (≥1500VAC/min)
Kukana kutchinjiriza	≥100MΩ (pakati pa zolowetsa/zotulutsa/magetsi)

Kugwirizana kwa maginito amagetsi	Malinga ndi IEC 61326-1(GB/T 18268), IEC 61326-3-1
Chizindikiro chosaphulika	[Ex ia Ga] IIC [Ex ia Da] ⅢC
Satifiketi yogwira ntchito yoteteza chitetezo	SIL3 motsatira miyezo ya IEC 61508
Bungwe Lopereka Chitsimikizo	CQST (China National Quality Supervision and Test Centre for Explosion Protected Electrical Products) (Malo Oyang'anira ndi Kuyesa Ubwino wa Zamagetsi Otetezedwa ndi Kuphulika)
Malo Ogulitsira 2-3、2-1 5-6,5-4	Um：250V AC/DC Uo=28V DC Io=93mA Po=0.65W Co=0.083μF Lo=4.2mH
Malo osungira 1-3, 4-6	Um：250V AC/DC Uo=7.2V DC Io=--- Po=--- Co=12μF Lo=---
Zofunikira pa malo okhazikitsa	Ikayikidwa pamalo otetezeka, imatha kulumikizidwa ku zida zachitetezo zamkati m'malo oopsa mpaka ku Zone 0, IIC, Zone 20, ndi IIIC
