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
