CD600 PLUS Multi-Loop Controller

The CD600Plus Multi-Loop Controller is a powerful stand-alone control device. Most importantly, it is capable of simultaneously controlling up to 4 loops. This is because it comes with a reach function block collection that can even customize the functionality of the front panel.   Besides that, the CD600Plus Multi-loop Controller counts 8 PID’s function blocks that are part of a control library with more than 120 function blocks.  that comes by default in the library.

As for control capability, the CD600Plus Multi-loop Controller can replace as many as eight traditional controllers, numerous signal conditioning modules, and wiring. Therefore, this stand-alone controller can replace up to 8 PID controllers and accomplish sophisticated strategies.  This includes, among others: step control, modulated On/OFF control, ratio, flow compensation, cascade, lead-lag, bump less transfer, batch control, linearization.

The high reliability of the CD600 Multi-loop Controller has earned a great reputation from a wide range of high-end users. Thousands of these units are spread all over the world, in all types of industrial segments. This covers from the most simple to the most complex controlling solutions.

The CD600Plus Multi-Loop Controller was designed, developed and manufactured by SMAR.  It is consolidated and trusted in the automation industry after many years of successful field proven experience.

As a result, flexibility and application versatility characterizes the CD600Plus Multi-Loop Controller.
Even more, programming the control strategy is accomplished by interconnecting the function blocks using and easy to learn graphical interface application for Windows.

CD600Plus Multi-Loop Controller OPC-Server

SMAR multi-loop controllers can be integrated in any DCS (distributed control system) that is compatible with the OPC standard. The SMAR CD600Plus OPC server will make the device data base of variables and parameters ready to the network. Besides, it also implements the communication traffic from the OPC Client to the CD600Plus.
