The Pertronic LED Display Relay Board is connected to the bus of a 12-way LED or Global LED display board. The LED Relay Board contains 8 non-latching relays that correspond to LED position numbers in the display. (Up to 255 for F100A systems and to 512 for F120 systems). Multiple LED Relay Boards may be used.
Each relay provides change-over contacts (no-c-nc), rated 1 A, 30 Vdc. The relay contacts are not monitored.
An active relay will remain steady (will not ‘flash’ as the LEDs do when active), and the relays will remain in their current state when the LED test function is operating.
