Electronic Systems Design releases the Model 050200A multi-price water vending machine controller, which utilizes the NAMA Multi-Drop Bus (MDB) protocol to interface with any MDB payment device. It can operate up to four (4) vending stations using only one MDB coin/bill acceptor. This controller has an accurate 1-, 3-, and 5-gallon metering system using either a flow sensor or internal timer, as well as a periodic UV flush cycle to refresh the system and remove standing hot water from the UV lamp housing.
