Description

RT484 is a multifunctional programmable controller with a universal input for the most common thermoresistances, thermocouples, and linear signals. The input has a built-in automatic software compensation of line resistance and cold junction temperature as well as automatic software compensation of temperature drift, and can be calibrated manually RT484 is also equipped with a programmable input filter and two 4-digit displays with programmable refresh rate. Available are various options for access restriction. The device can have up to 2 outputs (2 relays or 1 relay and 1 analog output), which can control variety of actuators through different programmable control algorithms. RT484 can work in manual or automatic mode, and an RS485 serial interface enables networking.
