ABB ControlMaster CM50 - 1/2 DIN Universal Process Controller

The ControlMaster CM50 is a highly versatile, universal 1/2 DIN PID process controller. Detailed process information is presented clearly on the CM50's full-color TFT display and an intuitive operator interface simplifies configuration and operation.

Highly scalable in both hardware and software functionality, a CM50 can be easily specified to meet the needs of virtually any process control application - simple or advanced. Powerful control functions such as adaptive control, math, logic and totalization provide problem-solving flexibility and make the CM50 suitable for a wide range of process applications.

Fully configurable via the easy-to-navigate front panel menus or PC configuration software, the CM50 can be commissioned rapidly and then tuned via the advanced autotune capability. MODBUS, PROFIBUS and Ethernet communication options ensure easy integration into a control system.

Finding the right process controller has just got easier with the launch of ABB’s ControlMaster range. Building on the highly successful Commander family, the ControlMaster range now offers an even wider range of control and indicator functions in just four easy to specify versions.

A key feature of the CM15 indicator and the CM10, CM30 and CM50 controllers is their full colour TFT display, providing operators with a clear and comprehensive display of process status and key information. Adjustment of the display via the customisation feature enables the operator to tailor their view to their requirements, while a chart display provides short term trending information.

The use of a TFT display also makes the ControlMaster range extremely easy to configure. Configuration menus are displayed in clear text, with no complex codes or abbreviations found on controllers with lesser displays. Further time savings during configuration are made possible by the use of built-in application templates, enabling operators to simply select the template best matched to their requirements, with the ControlMaster automatically configuring its I/O, display and control strategy to suit. Configuration can also be performed via DTM-based PC configuration software. Configuration files can be transferred to the ControlMaster via its front-mounted infrared port or stored locally on a PC.

The ControlMaster range offers a choice of communications options – Ethernet, Modbus, and Profibus. Ethernet communications provide the ability for users to be automatically notified of critical process events via email or remotely monitor the controller and process via the ControlMaster’s integrated webserver by simply using a standard web browser. For integration with larger control systems, the Modbus (RTU and TCP) and Profibus options enable access to real time data on process values and device status.

Other new features include additional control options alongside the standard cascade, ratio and feedforward control functions to help bring even the trickiest processes under control. Predictive control algorithms including dead time compensation, makes the ControlMaster ideal for applications with long dead-times such as pH dosing applications. Added control efficiency is enabled by the inclusion of adaptive control, which allows the ControlMaster to automatically adjust its control response to suit variations in process response. Dual loop control makes it possible to use one ControlMaster to control two processes. The inclusion of additional auto tuner, math, logic, gain scheduling, totalizer, custom lineariser and delay timer functions provide powerful problem-solving functionality.

With just four models in the range, product selection for basic through to advanced applications has never been easier. Initial model selection is made based on panel cut-out and then I/O and control functionality selected to suit application requirements. When required field upgrades can be easily performed using plug and play function keys and I/O cards. The common design of all of the four models provides standard operation and configuration across the range.

All products in the ControlMaster range feature full IP66 and NEMA4X protection as standard. These high levels of protection makes the range suitable for a wide range of industrial control applications, from arduous oil and gas facilities through to the washdown environments in the food and beverage industry.
