2704 – advanced multi-channel controller

Description

• High-performance measurements – the control in this class
• Flexible I/O – to meet many different needs
• Lots of functions – more than just a temperature controller
• Application-specific functions – simplifying complex applications
• Graphical softwiring – creativity and finding solutions to complex problems made easy

Its user interface is extremely flexible and easy to use thanks to the dot matrix display. Due to the high degree of configuration options, the 2704 offers many functions that are otherwise only found in programmable logic controllers (PLC). This enables system solutions that include not only process control but also control functions of individual system components, thus ensuring greater system transparency and reducing overall system costs.
The configuration can be carried out via the user interface on the device or via the iTools configuration software.

High precision process input

If you cannot make accurate measurements, precise control is not possible. The 2704 offers a typical resolution of 0.25uV, making it ideal for semiconductor, vacuum heat treatment and research applications. It offers input types for all thermocouples, Pt100 resistance thermometers and input linearizations such as 0-10Vdc and 4-20mA. 4-wire PT100 and PT25 measurement is also possible using a module that was specifically designed for high-precision metrology applications.

Setpoint programming

• Ideal for atmosphere or vacuum ovens and climate chambers
• 60 programs
• 3 profiles setpoint/program
• 600 segments
• 16 event outputs
• Program block display

60 setpoint programs can be saved, each with 16 digital events. A total of 600 segments can be programmed. Holdback, wait functions and digital inputs offer an extremely flexible solution for applications such as carburizing and vacuum furnaces, environmental chambers and autoclaves.

Digital communication

• ModBus RTU
• Ethernet Modbus/TCP
• Profibus-DP
• DeviceNet® network communication
• EI bisync
• Modbus master

The 2704 supports two slave communication interfaces. The modular design provides the operator with a selection of communication protocols that enable easy integration into an existing network or process control system.
The Master Modbus communication is a significant functional extension to the 2704. In its simplest form it can be used to transmit a setpoint from the master to a series of slave controllers in a multi-zone oven. Alternatively, it can also be used in conjunction with a Mini8 16 channel controller to provide the user interface with setpoint programmer functionality.
