The latest range of advanced process controllers from Eurotherm provideprecision control of temperature and a host of other process variablestogether with an abundance of advanced options making it the mostadaptable product in its class.

The emphasis is on flexibility yet the 3500 controllers still maintain ease ofuse. A simple ‘Quick Start’ process is used to configure all the basicfunctions essential to controlling your process. This includes input sensortype, measurement range, control options and alarms making ‘Out the Box’operation truly achievable. More advanced features are configured using aPC based graphical configuration tool enabling users to pick function blocksfrom a library then connect them together using soft wiring.

The large 5-digit display provides a clear and unambiguous indication of theprocess value. A four-line message centre provides custom or standardviews of important information to the user while vertical and horizontalbargraphs provide at a glance visual indication of the process. OEM Securityenables a user to protect their intellectual property by preventingunauthorised cloning of the configuration.

Dual loopTwo independent PID loops make the 3500 ideal for interactive processessuch as those found in carburising furnaces, environmental chambers andautoclaves. The loops may also be ‘soft’ wired together in creative ways tocreate cascade, ratio or other intelligent control strategies.

3500 SeriesDual Loop Controller/Programmer

Improve process efficiency, product quality and minimise waste

Setpoint programmerHeat treatment and other processes often requirethe ability to change setpoints with time. The dualloop 3500 has two programmers which can beconfigured as synchronised or independentprograms. 50 programs with up to two channelscan be stored with a total of 500 segments.

Input/output flexibilityA range of plug-in I/O modules caters forindividual application requirements minimisingstock and spares holding. A total of sixteenmodule types, including relay, logic, triac andanalogue, are available to fit into either three slotson 3508 or six slots on 3504.

2 | 3500 Series Data Sheet

Carbon potentialThe 3500 calculates carbon potential from measuring both theoxygen concentration and temperature of a furnace using azirconia probe. This enables a dual loop 3500 to be used tocontrol both carbon potential and temperature in anatmosphere controlled furnace.

Customised solutionsThe 3500 is more than just a process controller. It also providesa selection of application blocks including maths, logic andtiming functions offering the ability to develop custom solutionsand create cost effective machine controllers. The custom UserPage feature allows an operator to view current information in astyle most suitable to the process and terminology of theindustry.

CommunicationsThe 3500 is designed to integrate seamlessly withprogrammable logic controllers and other supervisory systems.A wide range of serial communication options are catered forincluding EIA232 and EIA485 using the Modbus RTU protocolalong with Profibus DP and DeviceNet. Ethernet connectivity isachieved using the Modbus TCP protocol.

RecipesUsing a PC tool recipes can be created that can be used tochange the operating parameters of the 3500 simply byselecting a new recipe via the HMI. This is very useful wheremultiple products are processed using the same controller butrequire different parameters to be set.

Infrared configuration adaptorCommunications to the 3500 can beachieved by using an infrared adaptor.Clipping onto the front fascia itprovides Eurotherm iToolscommunications allowing configurationand commissioning to be performedwithout the need to access the rearterminals of the controller.

Eurotherm iTools Graphical Wiring EditorThe GWE is anextremely easy way tocreate applications. Itallows users to selectthe function blocks theywish to use in theirapplication then connectthem together using‘Soft Wiring’. The GWEgives the user a pictorialview of exactly what hehas configured and can also be used to monitor runtimeconditions.

IO ExpanderExtra IO can be provided by the IO Expander. Options areavailable for 10in 10out and 20in 20out.
