This PID temperature controller is identical to our “1/32 DIN universal PID controller except it is powered by 12 V AC or DC (or 24 V AC/DC).   It can be used on automobile or places where high voltage power is not available. The controller only draws 100 mA at 12V. It can be easily powered by a car battery. One of the application is for controlling the temperaure of charcoal smoker with a DC fan in the field.  Another application is for cooling the CCD camera with thermal electric cooler (ETC or Peltier cooler).  It eliminates the need of a AC in the system. It can also be used as thermometer for air conditioner with alarm output on RV.

This universal temperature controller can be used as PID temperature controller, On/of temperature controller, Limit temperature controller, or simply as a thermometer/pyrometer with bright LED display and alarm output. It offers great value for its price. It is accurate, smart, and reliable. It is one of the smallest 1/32 DIN PID controller on the market.  Newly developed artificial intelligence enhanced PID algorithm and auto-tune function will control the temperature to one degree accuracy without complicated PID parameter fine tuning. This controller contains all the primary functions of an industrial grade PID controller but is also made very simple for the amateur user.

Recently, this controller has been upgraded with many new features. The cold junction compensation circuit has been improved for better accuracy when used with thermocouple sensor. A true on/off control mode is added. It is useful for controlling a refrigerator, motor, or solenoid valve that does not like to be switched too frequently. User can set the temperature and hysteresis band. It will work like a mechanical thermostat with better accuracy and tighter temperature range.  Limit control function is also added. It can be used for safety protection and special applications. When connected to a contactor, it can function as a latching relay. It will shut off the system if the temperature is out of control. The heater will not be turned on until reset manually. The limit control is also useful for applications that once the set temperature is reached, the system needs to be shut off automatically.  Except the limit control mode, all the other control modes can be set for either relay output or SSR control output by the user. When using the SSR output, the relay output can be used for alarm output. (Note, DC SSR must be used if the load is also powered by DC)

This unit is set for 12 V power supply by default. If you need 24V power supply, please make the selection below.
