E-90 Series controllers are designed using new generation microcontrollers for on/off and PID control. The unit has dimensions of 96x96 mm, conforming IEC/TR 60668.
 
E-90 Series have a 4 digits LED display range between -1999 and +9999, configurable universal inputs (T/C, R/T, mA) with 16 bit resolution, low calibration drifts with environmental conditions.
 
E-90 Series controllers have easy programming facilities to provide on/off and PID forms are used in every field of industry for measurement and control of temperature, pressure, level, current, voltage, resistance and other process parameters in industries such as iron & steel, cement, plastic, chemistry, metallurgy, petrochemical plants, refineries, ceramic, glass and others.
