Overview
Ing thermocouple input isolation safety barrier malyari yang mag-isolate ampo mag-convert kareng thermocouple (TC) signals kareng delikadung lugal keng 4-20mA current signals, ampo i-output nala keng safety zone. Ing safety barrier ayni atin yang built-in a cold junction compensation at malyari yang i-configure keng matalino. Ing tutuking range ning thermocouple malyari yang i-set kapamilatan ning computer software. Atin yang gagawan ing wire breakage alarm ampo out of range alarm. Ing produktung ayni mangailangan yang independenting power supply, a maki makabukud a power supply, input, ampo output terminals. Ing "*" mangabaldugan yang uri ning input ning thermocouple, at ing partikular a modelu mangabaldugan yang code (lawen ya ing "Input Signal Type and Range Table" para kareng detalye).
