PID Temperature Controller by Ajinkya Electronic Systems

a proportional–integral–derivative controller (PID controller) is a generic control loop feedback mechanism (controller) widely used in industrial control systems. a pid is the most commonly used feedback controller. this controller calculates an "error" value as the difference between a measured process variable and the desired setpoint. the controller attempts to minimize the error by adjusting the process control inputs.

we manufacture im2700 series temperature controllers, which are micro-controller based highly versatile controllers available with control algorithm as on / off, proportional, pi or paid 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 also available.

Features:
• micro-controller based digital circuitry four digits led display for parameter indication.
• optional 4 digit display for setpoint display.
• dustproof 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.
• high low relay alarm outputs optionally.
• 4-20 ma or 0-10 v control output optional.
• rs 232 serial interface for pc or serial printer (optional)
• size 96 x 96 x 150 mm. (Din standard).
• calibration certification as per iso9000 norms.
