Available in 1/8 and 1/4 DIN, these controllers are the very latest temperature and process controllers from Eurotherm. They combine Eurotherm's recognized expertise in measurement and control with a comprehensive and clear user interface using the latest LCD technology.
The large 5 DIGIT DISPLAY on the 3504 is complemented by the 4-1/2 digit display on the more compact, 1/8th DIN, model 3508.
Both models feature a 4 line ALPHA-NUMERIC DISPLAY to show process parameters and operator information, customizable messages and horizontal bar graphs.
The new ITOOLS GRAPHICAL WIRING EDITOR makes even the most ambitious configurations simple to implement. New printing features make the production of documentation required for process validation easier than ever to produce.
Customization of parameter names and lists is now provided. Parameters can be allocated to one of THREE SECURITY LEVELS to control user access. Any parameter can be promoted to an operator screen to ensure that vital information is always in view.
The SETPOINT PROGRAMMER offers 200 individuals program segments that can be allocated to any of the 50 programs.
The new ETHERNET MODULE provides modbus TCP/IP access to all important internal values and configuration parameters. A high speed block read for the most commonly used values minimizes network traffic and speeds up response. Any number of controllers can be monitored locally or remotely over the internet.
An INFRA RED PORT is provided on each front panel. This enables connection of the iTools configuration, monitoring and logging software without disturbing operation of the controller.
ALARMS can be logically combined to provide custom solutions from the simplest to the most demanding applications. Alarms can be configured as latching, non-latching or blocking. Custom messages can be displayed to provide operators with clear process specific information.
The DIN rail mounted IO EXPANDER can add a further 20 inputs and 20 outputs to the 3504 and 3508 controllers. All inputs and outputs are fully isolated.
The comprehensive COMMUNICATION OPTIONS, Modbus serial, Modbus TCP/IP, DeviceNet and Profibus, provide excellent opportunities for local, plantwide and worldwide system integration.
The standard REAL TIME CLOCK ensures that regular or routine actions can be triggered at a particular time of day.
The new motorized valve positioning algorithm provides not only single valve positioning (VP) heat or cool outputs, but dual valve position control for individual heat AND cool valve control. The controller can work with and without valve position feedback by using the bounded and unbounded control algorithm and can be configured to continue to function even if valve position feedback fails. The horizontal bargraph indicator graphically shows the valve position.
