The Yokogawa TMIL-505A is a Temperature mV Input Isolator from the UTAdvanced series. It is a DIN rail mounted signal conditioner designed for installation in control panels.
Its primary function is to accept a low-level millivolt (mV) signal from a temperature sensor (specifically a thermocouple), electrically isolate the signal to prevent ground loops and noise, convert it, and output a robust, standardized 4-20 mA DC current signal for transmission to a control system such as a PLC, DCS, or recorder. The -505A suffix typically indicates a specific input range and output configuration for thermocouple inputs.
