Invensys Operations Management introduced the Eurotherm Mini8 multi-loop PID Controller with EtherNet/IP communications. The Mini8 controller is an ideal partner to a PLC in multi-loop PID applications such as plastics extrusion and multi-zone furnaces. Leveraging the Mini8 controller’s built-in loop control, the PLC can concentrate on providing faster, more effective logic control without the burden of running complex control algorithms.  As part of the Invensys open-communication InFusion Enterprise Control System, the Eurotherm Mini8 controller supports serial, fieldbus and Ethernet protocols, including EtherNet/IP, making it easy to interface to intelligent masters such as programmable logic controllers.

A cost-effective alternative to designing and implementing accurate control loops in a PLC, the Eurotherm Mini8 controller not only provides better performance and easy configuration, it offers the same deterministic response and auto-tune feature as other Eurotherm panel-mount controllers from Invensys, and it can be easily integrated into the wider plant network, including other third-party systems.

This controller reduces engineering costs through using a dedicated PID device that enables quick and easy set-up of multi-loop and complex control strategies using pre-defined function blocks, and improves control performance by removing the burden of running complex control algorithms within a PLC. With input accuracy is +/-0.1% or better, the Mini8 Controller achieves  significantly better accuracy than analog control in small or medium PLCs. This controller calibrates through pre-defined routines, and features impressive minimal drift characteristics, which aid in operational ease of use.  

The Eurotherm Mini8 controller is suitable for use in a range of industry applications, including heat treatment (multi-zone ovens and furnaces), semiconductor CVD and MBE, power generation, packaging machines, textile machinery, baking ovens and glass lehrs. In addition, a pre-configured model designed especially for application in the plastics industry also is available.
