Product Description:

SMD-200 is designed for controlling food smoking process.  It can also be used for oven or kiln when second probe is needed for monitoring the process. It uses a PID algorithm to automatically adjust power to the heater to compensate disturbances from sun light and wind. It can hold the smoking temperature within one degree .  This controller has very similar function as our " dual probe plug-n-play smoker controller (model WSD-1200GPH or WSD-1501GPH). The main difference is that this component type controller can be configured to handle much larger smoker that requires more than 1800 Watts of power. User has the freedom to choice different sized relay (SSR) and power voltage. It also allow the user to integrate the controller into the smoker.  In addition, it has an extra relay output and accepts either PT1000 RTD sensor (Not PT100 RTD sensor) or type thermocouple. If you want to use two sensors at the same time, they must be the same type of sensors, i.e., either two PT1000 sensors or two type K thermocouples (see typical part lists here) The PT1000 RTD sensor provides high accuracy, the thermocouple sensor provides wider temperature range. Please choose the PT1000 sensor options above accordingly.

The controller has two sensor inputs. One sensor is for measuring the smoker cabinet temperature and the other sensor is for measuring the food temperature. Controller regulates the power output of the controller based on the temperature difference between  cabinet sensor and the set temperature. Food sensor is used to check the internal temperature of the food. It will tell the controller if it is the time to change the temperature of the cabinet, or the smoking is finished.  

The cooking temperature profile of the controller can be programmed up to 6 steps.  The ending criteria of each step can be determined by either preset time, or preset internal food temperature.  For cooking small sized foods or smoking the surface of the food, users can use the preset time as a reference point to finish the step. Using the internal temperature as the reference point is important for cooking large size food because it is difficult to know how much time is needed. For example: You can program the temperature to start at 120 °F for 1.5 hour of smoking, rise to 132 °F for 2.5 hours and finish at 190 °F until the internal temperature reaches 170 F. Then, the controller can either turn on a buzzer to let you know the food is ready, or drop the temperature to a lower set point to keep the food warm until you are ready to serve it. This will save you time waiting by the smoker to change the settings manually when each step is finished.  The program function can also been turned off so that user can use it as single set point controller for simple operation.

The main output of the controller is a 12V DC output. It is for controlling a solid state relay (SSR). The solid state relay will be used to switch the power of the heater. The controller also has two small electromechanical relay outputs. These two relays are synchronized with smoking program step.  Each one can be synchronize with one programming step.  For example, user  can use one relay to turn on a smoker generator  at step 2 of the cooking. Then, let the other relay to control a shower to cool the food at the last step of the cooking.

The controller has the ability to store up to 8 temperature profile for different recipes. 

Note: PT1000 probe options are also offered at same time. 2 x Connectors (PT1KCON) are included.
