Mini8 Controller

Brand: Eurotherm

The Mini8 Controller offers high performance control usually only found in Eurotherm panel mount PID controllers.

It is also a very competitive and compact data acquisition device.

Its modular design enables its I/O and feature set to be selected to cater for a wide range of applications from simple to complex.

The Mini8 controller is an ideal partner to a programmable logic controller.

Able to multi-drop on either serial, fieldbus or ethernet communications.

It offers an effective alternative to performing Analog measurement or loop control in a PLC.

Implementing these functions in the Mini8 controller PLC relieves it of the burden of performing Analog functions, often allowing a lower specification processor to be used.
