Description

RT18 is a programmable temperature ON/OFF controller with fixed input for various temperature sensors and linear signals. It is equipped with 3-digit LED display and relay control output. For easy mounting in existing cutouts, RT18 is available with 48×48, 96×48, 48×96, and 96×96 mm front sizes. To control its output, the device may utilize either ON/OFF or PI auto-tune control algorithm, the latter being a convenient solution that saves installation time and costs and provides precise control. The reliable operation in noisy industrial environment also extends RT18 application area.
