Profile Controller by Ajinkya Electronic Systems

Profile Controller is mainly used for controlling temperature or any other process parameter against time. The user can define the required time/temperature profile with the help of extensive instruction set like jump, loop, loop with count apart from the ramp and soak control. These are ideally suitable for temperature cycling applications, in environmental 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. The unit is available with control algorithm as On / Off, Proportional, PI or PID to choose from depending on process requirement.

Features:
• Microcontroller based Digital Circuitry
• Four-digit LED display for parameter indication
• Six digits display for programming and showing setpoint values
• Dustproof membrane keypad for programming.
• Up to 100 programs of 16 steps each
• Input interface: Pt 100 or Thermocouple or 4 t0 20 mA as per the requirement
• Control algorithm On/Off, P, PI or PID with programmable control constant
• Step change over temperature band programmable
• Programming instructions like Jump, loop, loop with the count, etc are supported
• Forward / Reverse control selection
• NV RAM storage to retain setpoint in case of power failure.
• Relay outputs rated 230V / 5A (resistive)
• Up to 2 Auxiliary relay contacts possible. (Optional)
• Independent Heat and Cool relay output optional
• 4-20 mA or 0-10 V Control output optional
• Size 96 x 96 x 150 mm. (DIN standard)
