The BVA is a 5 digit preset counter loaded with features never before offered. The BVA has 2 registers. One shows the set point continuously. The other totalizes the incoming pulses. At coincidence, a 5 Amp form C relay transfers. The totalizer meanwhile continues adding any incoming pulses to the total providing an accurate tally of overrun. One hand sets the BVA. Simply push the conveniently located set buttons and change the preset register. All standard voltages are available in a 50 x 50 mm rugged plastic case.
