Catalog excerpts

3500 SeriesDual Loop Controller/Programmer Improve process efficiency, product quality and minimise waste The latest range of advanced process controllers from Eurotherm™ provide precision control of temperature and a host of other process variables together with an abundance of advanced options making it the most adaptable product in its class. 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. The large 5-digit display provides a clear and unambiguous indication of the process value. A four-line message centre provides custom or standard views of important information to the user while vertical and horizontal bargraphs provide at a glance visual indication of the process. Configuation Lock enables a user to protect their intellectual property by preventing unauthorized cloning of the configuration. Dual loop Two independent PID loops make the 3500 ideal for interactive processes such as those found in carburizing furnaces, environmental chambers and autoclaves. The loops may also be ‘soft' wired together in creative ways to create cascade, ratio or other intelligent control strategies. 350H.0 Main Overview Unit 1 SP *3584.0 • Carbon potential • Custom user interface • Digital communications - Ethernet : DUAL RJ45 port - Modbus TCP Server and Client Setpoint programmer Heat treatment and other processes often require the ability to change setpoints with time. The dual loop 3500 has two programmers which can be configured as synchronized or independent programs. 50 programs with up to two channels can be stored with a total of 500 segments. Input/output flexibility A range of plug-in I/O modules caters for individual application requirements minimizing stock and spares holding. A total of sixteen module types, including relay, logic, triac and analogue, are available to fit into either three slots on 3508 or six slots on 3504. - Modbus RTU Server and Client - DeviceNet® network - Configuration Lock - Multi-language support (English, French, German, Spanish and Italian) V WATLOW Powered by Possibility

The 3500 calculates carbon potential from measuring both the oxygen concentration and temperature of a furnace using a zirconia probe. This enables a dual loop 3500 to be used to control both carbon potential and temperature in an atmosphere controlled furnace. The 3500 is more than just a process controller. It also provides a selection of application blocks including maths, logic and timing functions offering the ability to develop custom solutions and create cost effective machine controllers. The custom User Page feature allows an operator to view current information in a style most suitable...
