Lorentzzi - Model TCN4 -Digital PID Temperature Controller
The TCN4 Digital PID Temperature Controller, manufactured by Lorentzzi in China, is an economical solution for precise temperature regulation across various industrial applications. It utilizes an advanced PID algorithm for accurate temperature control, minimizing the difference between the set and actual temperatures. The device supports multiple input types, including thermocouples, RTDs, and analog inputs, and offers output options such as SSR, relay, and analog (4-20 mA or 0-10 VDC). The controller features RS485 communication for remote parameter adjustments via PLCs or touchscreens, and it provides versatility in heating and cooling functions, with 12 available alarm modes. The compact design, with a depth of 75 mm, allows for easy integration into industrial systems, and users can select from five panel sizes to suit their installation needs. The TCN4 controller is ideal for applications in coffee roasting, beer brewing, printing, injection molding, plastic manufacturing, and temperature management in ovens and furnaces.Digital pid temperature controller controls various heating elements to reach the set temperature by opening or closing the intermediate SSR or relay. On the right is our most advanced TCN4 pid temperature controller. This temperature controller is designed and produced in China, features realiable quality and competitive price.
High Light & Big Indicator
TCN4 temperature controller uses innovative LED lights as digital tubes to display temperature.
SSR&Relay Outputs
There are two outputs available, and the user can select the output to be a SSR or a relay output.
Multipile Inputs
Input temperature sensor types can be thermocouple, RTD, or 4-20 mA and 0-5VDC analog inputs.
Celcius & Farenheit
Users can change the temperature display to two formats: Celsius or Fahrenheit.
Analog Outputs
In addition to SSR or relay outputs, the output can also be 4-20 mA or 0-10 VDC, which can be used to control our SCR power conditioners.

Coffee roasting equipment
Manages rapid temperature changes during roasting to achieve consistent roast levels. Real-time adjustments prevent burning or under-roasting, preserving aroma and flavor.
Beer brewing equipment
Controls fermentation temperatures to optimize yeast activity and flavor profiles. Monitors and adjusts heat during mashing, boiling, and conditioning stages to prevent off-flavors.
Printing equipment
Stabilizes temperature in processes like ink drying or toner fusing. Prevents overheating or underheating that could cause smudging or misalignment, enhancing print quality.
Injection molding equipment
Ensures precise temperature regulation of plastic resin in barrels, nozzles, and hot runners, reducing defects like warping or incomplete fills and improving part quality.
Plastic bottle manufacturing
Regulates heat in extrusion and blow molding processes to maintain resin viscosity and mold integrity. Prevents defects such as uneven wall thickness.
Oven and furnace temperature control
Maintains uniform distribution heat in industrial ovens, kilns, or furnaces, dynamically adjusting heating elements to compensate for load changes or heat loss.
