Controllers

Minco specializes in standard and fully integrated custom control applications that offer a wide range of features to meet your needs. Our focus is on controllers you can trust to be accurate and reliable.

Control Method: A sophisticated control system is not necessarily the best control type for you application. Application parameters can vary widely from one application to another, and so can the ideal control method. What works well in one application may not work well in another, and different applications have different requirements that are better approached with certain control methods.

  • On-Off: On-Off control turns the controller output on and off at a specified temperature set-point, typically with hysteresis. The controller output is always either 100% on or completely off and can’t vary in between. On-Off is the simplest control method possible, which tends to make such controllers less expensive than other options and is well suited for miniaturization. Since the output is 100% on until the set-point is reached, it can be well suited for use with applications that require the fastest ramp up possible.
  • Proportional: Proportional control drives the controller output proportionally to the present error from the set-point – the farther the current temperature is from the set-point, the higher the controller output. It is typically driven with a Pulse Width Modulation (PWM) signal to achieve any output value between 0% and 100%. This allows the controller to more finely control the output and reduce the output as the set-point is approached, thus reducing overshoot and increasing stability. Proportional control works well with applications that require less overshoot or better stability than can be achieved with On-Off, but do not require the complexity of a PID system.
  • PID: PID control adds time functionality to the controller by integrating error over time and monitoring the rate of change of the error. This results in a control method that is highly adaptable and can be tuned to a wide variety of behavior. If well-tuned to the application, it is typically very stable despite potential destabilization while achieving a fast ramp up with little overshoot. PID is well suited for use with applications that have demanding control requirements that can support the added complexity of the PID system and tuning requirements.
  • Sensorless: Minco’s Heaterstat™ is a sensorless temperature controller. It uses a high TCR (Temperature Coefficient of Resistance) heater to sense and control the heat output – no separate sensor or thermostat is required. The solid state electronics are more durable than a conventional mechanical thermostat, and utilizes an adjustable set-point which allows you to fine tune the control temperature for your application. All that is required for temperature control is an AC or DC power source, the Heaterstat™ controller, and a matching heater.

A variety of controller package options are available depending on the requirements of the application. These packaging options can vary in size, shape, type of terminations, and mounting.

  • Stand-alone: Pre-packaged controllers are excellentControl DIN for drop-in applications. Multiple connection options are feasible, including terminal blocks for quick wired connections or fixed-length wire leads. Industry standard configurations are also available in a compact 1/16th DIN enclosure.
  • Board-mount: Board-mount controllers are a great option for applications that require integration of the controller into a larger system. They use a Single In-line Package (SIP) and areController PID designed to be directly mounted to a PCB. The controller handles the control processing and switching load so your system doesn’t have to, while at the same time provides an interface for real-time feedback and configuration.
  • Flexible Circuit: Integrating controls or electronics directly on to flexible heater, circuits, and sensing designs can reduce the total system cost, reduce the number of products that need to be managed and Controller Integrated Solutionsimplify the installation.

Minco’s controllers offer a wide variety of performance options, including AC and DC power and switching, high current capabilities up to 15 amps, multiple inputs and outputs, auto-tuning capabilities, high voltage switching, RTD or Thermocouple inputs, output isolation for safe wiring, a variety of communication options, high-speed control loops, solid state or mechanical switching, high accuracy, and local indication.

UL, CE, FM, and more. Minco has experience with many different regulatory agencies and can adjust design specifications to meet these stringent requirements for safety, EMC, and explosive atmospheres.

Control Prototyping

Minco’s CT425 is perfect for engineering prototyping activities. This PID temperature controller is capable of reading two independent temperature sensors (RTDs). By utilizing an internal solid state relay, logic voltage output, and internal mechanical relay, the controller is fully configurable. Simply connect the CT425 to a laptop or PC to configure.

  • Inputs: Utilize one or two platinum RTDs
  • Outputs: Utilize up to three outputs (solid state relay, logic voltage, mechanical relay)
  • Choose any control type from PID, On/Off, and Alarm
  • Communication over USB and a user-friendly software package
