  Description  
 

The Temperature Controller Solution, based on Cypress’s PSoC® programmable system-on chip device, is a universal input temperature controller that supports RTD, J, K, R, and S types of thermocouples, 4-20 mA current input, and 0-10 V DC input. The solution runs the PID algorithm with auto-tuning feature.

The analog integration in PSoC makes it a single-chip solution and eliminates the need for external components such as Programmable Gain Amplifier (PGA), voltage reference, and analog multiplexer that are required for signal conditioning. The solution has automatic cold junction compensation. It is also compensated for drift and stability over the entire operating temperature range.

The measured temperature is displayed in a four-digit, seven segment display. There are user keys to set parameters such as type of temperature sensor, set points, and hysteresis. The settings are stored in an on-chip flash memory. There are two programmable relay outputs - one for heating and cooling and one for PID logic. The solution is based on PSoC 1 (CY8C28452) and available in a small form factor. It is designed and developed by Triveni Electronics, one of Cypress’s premier design partners in India. The solution is highly programmable for any temperature sensor input and can be quickly customized to meet the specific needs of any temperature controller / indicator vendor.
