Libratherm offers single input one ramp and one soak which are suitable for applications where time dependent control is required, such as in tampering furnaces and powder coating or paint baking ovens. When the process temperature reaches the soaking temperature an event relay output is energized and the internal soaking timer starts to indicate the start of soaking time. At the end of the soaking time the same relay is deenergized to indicate the end of soaking time. The time and temperature both are user programmable through front panel keyboard. The control action is pid or on/off, which is user selectable. These models are available in 72 x 72 x 120 mm and 96 x 96 x 160 mm sizes respectively in metal enclosure with abs front and they operate on 230 vac supply.
