Unitronics' V130-33-R34, the small palm-sized PLC with an integrated HMI, was chosen by Waterplay Solutions to be installed in one of their recreational sites, in Texas.
With thousands of installations world-wide, Waterplay® Solutions Corp. has provided their customers premium aquatic recreational features since 1987. Offering a variety of products designed to turn any space into an exciting attraction, Waterplay® responds directly to their customer needs; including aquatic play features, slide activity centers, waterslides urban water features, and water management solutions.
With one particular project Waterplay® was working on in Texas, they had an aquatic play pad that had a very small area where a PLC controller could be placed. In their existing line of controllers they were using at the time, they specifically needed a digital output to control a relay, and the particular manufacture they were using did not have a PLC with high enough rated built in relays to operate the valves that they used. As a result, they were on the search for a PLC with an integrated HMI. The controller need the following operations either built in or programmable to meet their requirements:
Programming requirements:
• Start/stop time for the week
• To be able to have the system on/off for each day of the week
• Receive an input from the field to start a sequence
• Log number of activations/per day and downloadable
• Automatically open/close each output
• To have internal relays that can operate a solenoid valve that requires 0.41amps of in rush current (0.25 ampsholding)
• Relatively easy to program with minimal cost for software
• Field reprogrammable with a flash card
Physical requirements:
• To be able to fit in a 6 x 10 inch space
• Multi line graphic interface
• Expandable without taking up additional space, or using minimal additional space.
"The Unitronics V130-33-R34 was able to reach these requirements and more." Said Carney Neave of Waterplay® Solutions Corp. "The controller was very easy to program and customize for our application. The staff and tech support of Unitronics are very efficient and knowledgeable.
"Unitronics is proud to be a part of Waterplay's role in bringing the joy of water to people and communities. "We do more than build aquatic play features. We've helped turn crime-ridden downtown parks into family attractions." Says Neaves. "We've given new life to abandoned community facilities, bringing kids back to play in them. We work with you to create environments that promote exploration and discovery, fostering imaginative, interactive play."
