Description
RT28U-R is a modification of RT28U for rail mounting. 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. The device has 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. Thanks to its universal input, serial interface, and excellent price-to-performance ratio, RT28U-R is a widely applicable device.
