PLC control cabinets ah signal isolators chiah

Riantuannak riantuannak ah, PLC (Programmable Logic Controller) control cabinet nih a biapi tukmi rian an ttuan, sensor le actuator phunphun in signal cohlannak rian an ttuan, cun chunglei logic riantuannak hmangin thilchuah ningcang ttha tein uk khawhnak an ngei. Sihmanhsehlaw, hmannak ah, PLC control cabinet pawl nih a harmi electromagnetic pawngkam phunphun le signal hnahnawhnak buaibainak an tong tawn, cu nih cun control system riantuan ningcang lo, a rawhnak a chuahter lengmang, cun thilri le riantuantu himnak caah tihnung a siter khawh. Cucaah, chap a dang tein chiahmi hmelchunhnakators to PLC control cabinets cu a tlangpi in a phichuak ah a cang.

Signal isolators hna i an rian nganbik hna cu electromagnetic hnahnawhnak kuatnak khamnak, system rawhnak a chuah lonak zorternak, le hmunhma ah thilri rawhnak a um tikah isolation peknak, control system dihlak ah rawhnak karhternak khamnak hna an si. PLC nih a hmuhmi signal pawl kha semiconductor thilri hmangin thlen le thlen in, cun optical asiloah magnetic sensing thilri hmangin thleidan le thlen in, a donghnak ah demodulate tuah in a hramthawk signal asiloah signal dangdang ah thlen ṭhan in, hi thil tuahnak nih signal a fekmi le a dikthliar in a fehter, cu pin ah PLC rawhralnak zong a kham i PLC cung i signal nih a chuahpimi hnahnawhnak kha a zorter, a hleiin hnahnawhnak hmelchunhnak. Cun, signal isolators nih signal thlennak zong an tuah khawh, cu bantuk cu PT10 pehtlaihnak in signal kha 4-20mA signal ah thlen le PLC system ah khumh, electric le thazaang chuahnak karlak i buainak kha ttha tein hrial khawhnak le loop le thilri karlak i i hnahnawhnak kong buainak kha ttha tein a tawlrel khawh.

A bik in hmannak ah, thir sernak sehzung chuahnak line tibantuk ah, tahnak le uknak cu PLC, hmunhma ah mah tein riantuan khawhnak thilri le hmunhma ah riantuantu hna hmangin tuah khawh a si. PLC cu hmun in meter za tampi aa hlatnak ah a ummi control cabinet ah chiah a si (innchung lumnak ah rian a ttuan), cun hmun in a chuakmi automation thilri asiloah thermocouples nih wire hmangin control cabinet chung i control cabinet chungah signal an chuah. Hika zawn ah, PLC chung a lutmi signal cu a dang tein chiah a hau i thlen zong a hau men lai, cu bantuk cu 4-20mA thleidannak le PLC chung a luh hlanah 0-5V ah thlen tibantuk a si. Thermocouple signal pawl thleidannak le thlennak a dihmi thilri cu "thermocouple signal isolator" asiloah "thermocouple temperature transmitter" tiah auhmi a si. A riantuannak hrampi ah hin luhternak signal le chuahnak signal thleidannak, cun thermocouple in luhternak mV level signal kha standard industrial signals (4-20mA, 0-5V, 0-10V) ah thlennak aa tel.

A tawinak in chim ahcun, signal isolators chiah cu riantuannak thilri hna zumhawktlak sinak tthanchoternak, rawhnak tlawmternak, PLC thilri kilvennak le signal tthatnak tthanchoternak caah a biapi tukmi a si. Control system hna i fek tein le zumhawktlak tein riantuan khawhnak ding caah a biapi mi thilri pakhat a si
