Eaton MTL5582 Intrinsically Safe Barrier

Product Overview
The Eaton MTL5582 is a single-channel intrinsically safe resistance isolator in the MTL5500 series. It connects to an RTD or other resistance sensor in a hazardous area, provides galvanic isolation, and repeats the resistance signal to a safe-area monitoring system. It is typically used with Pt100 3-wire RTDs.
