Industrial Temperature Controllers

IM3700 Series Temperature Humidity controllers are Micro controller based highly versatile controllers for combined control of Temperature and Humidity. Controller is available with PID control algorithm. Control parameters are user configurable on site. Controllers are available which can accept input from different type of Humidity sensors as well as RTD sensor for Dry Bulb / Wet Bulb measurement technique.Useful in pharmaceutical industry, environment chambers, green house rooms etc. Features • Micro controller based Digital Circuitry • Two Row Four digit LED display for parameter indication. • Dust proof membrane keypad for programming. • Input interface : Pt 100 RTD for temperature. RTD for Dry / Wet bulb technique. or 4-20 MA from Humidity sensor or 0-10 V or 0-3 V from Humidity sensor. (Factory set). • Control algorithm independent PID • NV RAM storage to retain set point in case of power failure. • Control output : Relay outputs rated 230V / 5A (resistive) or Open Collector Outputs. High Low set point with Relay output for Compressor control. • RS 232 Serial Interface for PC or Serial Printer (Optional). • Real time Clock (Optional).

Profile Controller is Process Controller for controlling process parameter against time.

User can define the profile he wants with the help of extensive instruction set. Unit supports instructions like jump, loop, loop with count apart from ramp and soak control.

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.
