Description

RT28U is designed for wide range of applications. It is equipped with a 3-digit LED display, a universal input for Pt100, Pt1000, PTC, 6 thermocouple types as well as for linear current, voltage, and resistive signals from external transmitters and can have up to 2 programmable relay control/alarm outputs. RT28U can be ordered with either keyboard, or unique rotating encoder for set-point adjustment and programming. All modifications have a built-in circuit for self-testing and self-calibration, manual measurement offset setting, and automatic software compensation of line resistance and cold junction temperature. The display-to-input correspondence (in case of linear input), decimal point position, temperature measurement unit, and offset value are also programmable. The display-to- input correspondence (in case of linear input), decimal point position, temperature measurement unit, and offset value are also programmable. Thanks to its universal input, the available various enclosures, serial interface, and excellent price-to-performance ratio, RT28U is an exceptionally widely applicable device.
