3500 Series Dual Loop Controller/Programmer
Brand: Eurotherm
The emphasis is on flexibility yet the 3500 controllers still maintain ease of use.
A simple 'Quick Start' process is used to configure all the basic functions essential to controlling your process.
This includes input sensor type, measurement range, control options and alarms making 'Out the Box' operation truly achievable.
More advanced features are configured using a PC based graphical configuration tool enabling users to pick function blocks from a library then connect them together using soft wiring.
