Detailed Product Description

Ajinkya Temperature controllers are Microcontroller based highly versatile controllers available with control algorithm as On / Off, Proportional, PI or PID to choose from depending on process requirement. Control parameters are user configurable on site. Various options like independent Heat / Cool relay output, input from sources like Rtd, Thermocouple or 4-20 mA etc are available. Other versions of temperature controllers are also available as " Profile Controller : To control temperature against time. E.g. Ramp Soak Control" Temperature Humidity Controller " Multi setpoint Temperature Controller " Multi Channel Temperature Controllers : Multiple Temperature Controllers in a Single Package. Upto 48 Channels. Features" Microcontroller based Digital Circuitry" Four digit LED display for parameter indication and 4 digit for setpoint indication." Dust proof membrane keypad for programming." 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. " NV RAM storage to retain setpoint in case of power failure." Control output Relay outputs rated 230V / 5A (resistive) or 4-20 mA " Independent Heat and Cool relay outputs optional."
