E+PLC400 modular PLC

E+PLC400 is a PID controller, recorder and PLC combined in a single, modular solution which is incredibly easy to engineer. Using an open industry standard (IEC 61131-3) platform and a single, integrated programming and visualisation environment, this innovative instrument is designed to offer flexibility to match process requirements while reducing engineering time. It is feature rich and gives an enhanced user experience which delivers operational efficiency, better process performance and easier regulatory compliance.


All the pieces of your process puzzle with added versatility and scalability

E+PLC400 combines full PLC functionality with unique Eurotherm control and recording capability made available in rapidly engineered function blocks. It is available in a choice of base sizes, is scalable to suit current and future process needs, and comes with a versatile range of precision I/O modules.

E+PLC400 uses CODESYS, a leading open platform, to provide a familiar programming environment with a range of IEC 61131-3 languages available to ensure ease of use. Easy, flexible visualisation is provided by the connection of up to two local operator panels as well as the ability to view the process via a web server on mobile devices such as PCs, tablets and smartphones; all quickly configured with automatic tag recognition within the same programming environment as the PLC.

Precision measurement

To control accurately, you need to measure precisely. The modular form of the E+PLC400 enables the incorporation of a versatile selection of precision I/O modules which enable accurate control and recording. Analogue and digital I/O, relay outputs and zirconia input are all available for inclusion in a selection of base sizes to exactly match application needs. Its high performance I/O gives accurate measurements, enabling tighter control and an exact historical record of a process.

A versatile solution for small to medium-sized applications

Best in control

E+PLC400 incorporates over 50 years of control knowledge including the unique Eurotherm autotuning PID algorithms that provide a superior control performance.

  • Reduce process times by getting to the setpoint quickly
  • Optimise energy usage by eliminating overshoot or undershoot while still providing rapid control response
  • Improve quality by giving stable control performance with tighter tolerances
  • Provided in pre-engineered function block form that you simply need to parameterise

Cost effective, superior control performance – why compromise?

Easy setpoint programming

Feature rich, the E+PLC400 includes highly flexible, easy to use setpoint programming. Using a spreadsheet style format, multiple programs with numerous segments can be quickly configured ensuring easy setup and improved operational efficiency.

Guaranteed operation which can lower processing costs

Best in recording

E+PLC400 has integrated recording capability with highly efficient batch data management strategies to ensure total data integrity and security. It provides complete peace of mind by using decades of recording expertise to ensure compliance with both regulatory and quality standards through:

  • Continual secure recording at point of measurement
  • Incorporating power and network fail strategies ensure to complete data integrity
  • Complete record/batch traceability with all process and metadata securely stored together
