Detailed Product Description

BTC484 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. The operator can calibrate the input manually. BTC484 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 may have either two relay outputs or an analog plus a relay output, which can control variety of actuators through different control algorithms - ON/OFF, PID plus ON/OFF, PID-pulse, PID-step and analog PID. Provided is also an auto-tuning mode. BTC484 enables the operator to work in manual or automatic mode, and the RS485 option enables networking. The device can be manufactured with one of the following 4 DIN front-panel dimensions: 96x96, 48x96, 96x48, and 48x48, or in a case for DIN-rail mounting.
