Overview

Ing thermocouple input isolation safety barrier malyari yang magtransmit keng millivolt signal ibat keng thermocouple (TC) keng delikadung lugal papunta keng ligtas a lugal keng 1: 1.

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).
