Other Details

We offer profile controllers that are used as a process controller for controlling process parameter against time. The profile controllers help the user in defining the profile with the extensive unique instruction sets like jump, loop, loop with count apart from ramp and soak control. To operate external controls like valve or hooter auxiliary relays are provided with these profile controllers. Some striking features of the profile controllers include:

• Microcontroller based Digital Circuit
• Four digit LED display for parameter indication
• Six digit display for programming and showing set point values
• Dust proof membrane keypad for programming
• 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 constants
• Step change over temperature band programmable
• Programming instructions like Jump, loop, loop with count, etc. supported
• NV RAM storage to retain set point in case of power failure
• Upto 2 Auxiliary relay contacts possible
• Independent Heat and Cool relay outputs optional
• 4-20 mA or 0-10 V Control output optional
