UL LISTED RELAY BOXES distribute power to the appropriate device to be operated as a result of commands entered at the touch screen. Relay Boxes are dual powered and sized to accept two 120-volt, 30-amp, single phase circuits per Relay Box. Each Relay Box comes standard with eight sets of 30-amp momentary contact relay pairs as well as two 30-amp auxiliary relays. The momentary contact relay pairs are for controlling directional functions of gymnasium equipment or similar devices. The auxiliary relays are to control separate circuits (UP TO 250 VOLT, 30-AMP, SINGLE PHASE) to control continuous contact items such as stage lights, PA systems, Shot clocks or Scoreboards. Continuous relays require their own dedicated power source. Relay Boxes are surface mount design and measure 12”x16”x4” (279 MM X 368 MM X 83 MM). Relay Boxes should be mounted in a position to minimize high voltage wire runs.
