Kethu jam poko lanyuth iwi PLC control cabinets

I thenge mi tic mi cuma, PLC (Programmable Logic Controller) control cabinets timo tic ma pire tek, ma gitiye ku tic mi gamo lanyuth kud i sensors man actuators matung tung, man mi nwangu loc maber pa tic mi yubu piny nikadhu kud i tic mi logic ma iye. Ento, i tic ma jutimo, PLC control cabinets pol kare nwangu peko mi electromagnetic matung tung man peko mi signal interference, ma copo telu tic marac pa control system, rwinyo kare ku kare, man nyayu lworo ikum jam tic man jurutic. Pieno, medu lanyuth ma jupokoators ni PLC control cabinets udoko piny ma dhanu zo timo.

Tic ma pire tek pa signal isolators uketho i iye juku nyai pa electromagnetic interference, jwigo peko pa jam tic, man miyo isolation ka jam tic moko utur i kabedo, juku nyai pa peko i system mi tela zo. Ni loko man loko lembe ma PLC unwangu nikadhu kud i jam tic ma julwongo ni semiconductor devices, man i ngeye poko man loko gi ku jam tic ma nen ku wang nyo magnetic, man i ajiki demodulating man loko gi ni signal macon nyo signal matung tung, yub eni ketho signal bedo maber man ma atira, man eketho PLC kud unyothre man dwoko piny adwogi pa signal ikum PLC, asaga lanyuth ma nyai. Mi medo, signal isolators copo bende loko signal, calu loko signal kud i PT10 ni 4-20mA signals man ketho gi i PLC systems, ma jwigo lwiny ikind mac ku mac man jwigo peko mi turo lembe ikind loops ku jam tic.

I tic moko, calu i tic mi yubu cuma, pimo man yub jutimo ku PLC, jam tic ma timo tic kende kende, man jam tic ma tiyo kende kende. PLC juyike i cabinet ma juketho mita miya mapol ku kabedo (ma timo tic i rwom ma piny), man jam tic ma timo tic giri nyo thermocouples kud i kabedo ne cwalo lanyuth nikadhu kud i waya i cabinet mi control i ot. I kare eni, lanyuth ma mondo i PLC umaku ubed kende man ecopu bedu mitere ni loko, calu poko 4-20mA man loko ni 0-5V mapodi emondo ngo i PLC. Jam tic ma daru poko man loko thermocouple signals julwonge ni "thermocouple signal isolator" nyo "thermocouple temperature transmitter". Tic pare madit uketho i iye poko rwom pa mV ma wok kud i thermocouple ni rwom pa tic (4-20mA, 0-5V, 0-10V).

I ayi ma kicoko, ketho signal isolators ubedo piny ma pire tek pi medo gen pa jam tic ma timo tic kende kende, dwoko piny peko, gwoko jam tic pa PLC, man medo ber pa signal. Etiye acel ikin piny mapire tek mi neno nia tic maber pa jam tic mi tela utiye maber man ma gen
