Profile Controller are mainly used for controlling temperature or any other process parameter against time. User can define the required time / temperature profile with the help of extensive instruction set like jump, loop, loop with count apart from ramp and soak control. These are ideally suitable for temperature cycling applications, in environment chambers and furnaces etc. Auxiliary relays are provided which can be used to operate external controls like valve or hooter etc. Relay On and Off instructions are supported. Unit is available with control algorithm as On / Off, Proportional, PI or PID to choose from depending on process requirement.
