Invensys Eurotherm Mini8 multiloop PID controller

Invensys Operations Management has introduced EtherNet/IP communications to its Eurotherm Mini8 multiloop PID controller.

The Mini8 controller is a suitable partner to a PLC in multiloop PID applications such as plastics extrusion and multizone 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.

The 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 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.

Input accuracy is ±0.1% or better, significantly better than analog control in small or medium PLCs, and the Mini8 is suitable for use in regulated industry applications, including aerospace metal heat treatment.
