EUROTHERM 2216E TEMPERATURE CONTROLLER 11:45

The Eurotherm 2216e is a compact, versatile, and highly reliable single-loop temperature controller designed for industrial process control. It is a digital panel meter that automates the task of maintaining a precise temperature by reading a sensor (like a thermocouple) and controlling an output device (like a heater or cooler).

Key Features & Specifications

• Manufacturer: Eurotherm (A renowned and highly respected British manufacturer of precision industrial control systems, now part of Schneider Electric). The brand is synonymous with quality and reliability in harsh environments.

• Model: 2216e – This indicates it’s part of the 2216 series, with the “e” often denoting an enhanced or specific variant.

• Type: PID Temperature Controller. PID (Proportional-Integral-Derivative) is a sophisticated control algorithm that not only turns the output on/off but adjusts the power level precisely to maintain a stable temperature without overshoot or oscillation.

• Input: Accepts a wide range of industry-standard temperature sensors:

  • Thermocouples (Types J, K, T, R, S, B, N, E)

  • RTDs (Pt100)

  • Voltage and Current signals (0-10V, 0/4-20mA) for use with other process sensors.

• Outputs: Typically offers multiple output options (configurable):

  • Relay Output: (e.g., 5A SPDT) for directly switching heaters, contactors, or solenoid valves.

  • SSR Drive: (e.g., 12V DC) for controlling solid-state relays (SSRs) for fast, long-life switching.

  • Analog Output: (e.g., 0/4-20mA or 0-10V) for controlling proportioning valves or variable speed drives.

• Display: A bright, easy-to-read LED or Vacuum Fluorescent Display (VFD) that shows the Process Value (PV) (actual temperature) and Set Value (SV) (desired temperature).

• Control Algorithm: Advanced PID with features like Autotune (the controller automatically calculates the optimal P, I, and D values for the system it’s connected to), manual tuning, and alarm functions.

• Enclosure: Designed for panel mounting in a standard DIN cutout (e.g., 1/16 DIN or 1/8 DIN), making it a staple in industrial control panels worldwide.

What is it used for? (Purpose)

This controller is the “brain” for any application that requires precise and stable temperature regulation. Common applications include:

• Industrial Ovens & Furnaces (for heat treating, curing, drying)

• Plastic Processing Machinery (extruders, injection molders)

• Packaging Equipment

• Food and Beverage Processing

• Environmental Chambers and Test Equipment

• HVAC systems for specialized industrial heating

Who is this for? (Ideal User)

This is a professional industrial component for:

• Industrial Electricians and Control Systems Technicians.

• Maintenance Engineers in manufacturing plants.

• Process Engineers.

• Machine Builders and Panel Builders.

• Advanced Hobbyists or Lab Technicians working with high-temperature processes (e.g., kilns, foundries).

Important Considerations for a “USED” Unit

1. Configuration: This is a highly configurable device. Its behavior depends entirely on how it has been programmed (e.g., input type, output type, PID values, alarm settings). A used unit will likely need to be completely re-configured for your specific application.

2. Documentation: Access to the user manual or datasheet is essential to understand how to wire it and program it correctly.

3. Physical Condition: Check for signs of overheating on the terminals or display failure.

4. Calibration: While generally very stable, the accuracy of the input reading may need to be verified or calibrated against a known standard if precision is critical.
