Pioneering HVACR controls company Resource Data Management (RDM), has announced the launch of a new product that dramatically expands the capability and application range of its plant and building control technology. The new PRO 600 expansion modules provide a massive expansion for its Mercury Plant Controller – giving an extended number of inputs and outputs.

 “We believe the arrival of this new capability for the PRO 600 will challenge existing solution providers and be a wake up call in terms of cost and flexibility”, says Steve Nicoll, sales and marketing director of RDM. “It is very low cost but highly effective. Against any measure it delivers the goods. It is going to be a serious contender in a market where performance and value for money are increasingly under scrutiny.”

The system can be used to control and monitor any kind of plant – including refrigeration, hvac, lighting, security, process and so on – on any scale, from the level of single items of equipment up to complex, estate-wide distributed systems. For the first time it offers the ability to control bi-polar stepper motors, often used to govern the action of incrementally operated devices such as air dampers in VAV systems, according to the company’s press release.
