EZ-ZONE® RUI and Gateway

Configure ProductRequest Information
The EZ-ZONE® Remote User Interface (RUI and communications gateway) can be utilized as a communication gateway device to save cost, space and wiring when digital communications is being used with two or more EZ-ZONE controllers. The EZ-ZONE RUI can also serve as a display for showing all parameter values for up to 16 EZ-ZONE controllers, again saving cost, space and wiring expenses.

Indicator Features and Benefits-Remote User Interface (RUI)

Single user interface device or location to access multiple controllers
  • Easy accessibility to all controllers and all parameters from a central location by using one RUI display
  • Reduces component material costs by using a single RUI to display multiple control zones
  • Eliminates cost and complexity from bringing all controller related input and output wiring to the front panel
Flexible use of a display interface
  • Can be used when needed during normal machine production, for OEM prototype design purposes or for remote troubleshooting scenarios
  • Ability to use more than one RUI indicator to display additional data including temperature and current (ammeter) to improve user system interface

Communications Gateway Features and Benefits

A single RUI and gateway provides field bus access for up to 16 EZ-ZONE controllers
  • Lowers solution cost when field bus communications is required for multiple loops
Expand communication protocols to all EZ-ZONE controllers
  • Ability to utilize multiple communication protocols for different user preferences. Flex between different communication protocols while still maintaining a reduced level of inventory
Delivers multiple communication protocol options
  • Ability to connect EZ-ZONE controllers to communication networks utilizing
    • Modbus® RTU
    • DeviceNet™
    • EtherNet/IP™
    • Modbus® TCP
