RDM upgrades Intuitive PLC controller

UK: Resource Data Management (RDM) has announced the launch of a new generation of its Intuitive TDB Controller for use within PLC applications across the HVACR sector.

Available from today at the same low cost as previous hardware, RDM says the V2 Intuitive TDB Controller is designed to increase flexibility, simplify the install and set-up process and reduce installation costs.

The new controller boasts a range of new and enhanced features including optional built-in colour LCD, extended temperature range, dual ethernet ports, four PWM outputs and increased processing power and memory.

RAM is four times larger, the flash storage has increased sixteen-fold and the processing power has doubled, providing users with a faster experience when using the device, and more memory space. The optional built-in display replaces the older display allowing for values, graphs, gauges and other graphics to be displayed.

The controller can communicate to Modbus devices and connect via BACnet protocols as well as the RDM standard XML over IP. In addition to the device inputs and outputs, Intuitive TDB controllers feature a mix of built-in communications ports including USB, and CAN bus for simple connectivity to devices and peripherals. Web services are available over IP.

Previous hardware had a single ethernet port, the new hardware variant has two. These dual ports can act as a network switch, negating the need for a separate network switch, whilst minimising the amount of cabling required to reduce installation costs further.

With the addition of a USB wi-fi adapter, also available from RDM, the Intuitive TDB controller can communicate over wi-fi networks without network cables. A built-in IP network interface can facilitate connection to RDM’s DMTouch or an IP network without the need for an extra communications module.

Four new PWM analogue outputs enable the device to output pulse width modulation. When configured using TDB (The Data Builder) licence-free PLC editing software from RDM, the controller can support strategy controls, including EEV, or evaporator fans.

“The new features and enhancements added to the Intuitive hardware, have been designed following consultation with our customers and thorough research by our technical engineers, to present one of the most advanced PLC controllers in the marketplace,” said RDM CEO Andrew Chandler.
