The JUMO dTRON family of modular PID profile controllers is capable of 2-state, 3-state, modulating, or continuous control.  An 8-step ramp and soak profile capability is standard on each unit.  Being modular, the dTRON can be configured to match your specific needs: multiple analog inputs, multiple analog and relay outputs –  including a solid-state relay option, RS422/485 communication, supply for 2-wire transmitters, a math and logic module, auto-tuning, alarms, timers, and ratio/humidity/differential controllers are all available.  The dTRON Plast controller specifically designed for the plastics industry (extruders, injection molding, hot channel runners) is available along with compatible temperature and pressure sensors.
