Maximize PID Control with the Mini8 Controller
Enhance your PLC solution with Eurotherm PID Features
The Mini8 Loop 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 Loop Controller is the ideal partner to a programmable logic controller (PLC). Able to multi-drop on either serial, fieldbus or Ethernet communications, it offer s a real, cost-effective alternative to performing analog measurement or loop control in a PLC.
Implementing these functions in the Mini8 Loop Controller reduces the hardware cost of the PLC, relieving it of the burden of performing analog functions – often allowing a lower specification processor to be used.
The feature set of the Mini8 Loop Controller includes high performance PID control, graphical wiring and setpoint programming functions together with math, logic and timing function blocks.
When used in a data acquisition installation the high density analog I/O can be combined with 6000 Series paperless graphic recorder products to provide unsurpassed local and network access to your process.
