LED Annunciator Panel

 

The LED Annunciator Panel is a fully redundant panel that has 15 individual display cells of which each cell contains 2 ultra bright LEDs. Each cell color and text is fully configurable. The unit automatically self tests during power on. The compact design with one MS connector eliminates the need for multiple individually wired indicators cutting material and installation costs; as well as increasing reliability.

Each cell’s LEDs are powered from separate power supplies allowing redundant operation.  If one power supply fails only one LED per cell stops operating. Power on self test function incorporates 2 independent systems to prevent either from failing the display system. One LED in each cell is illuminated continuously while the other LED flashes at 1 second on off rate for 10 seconds. This allows all LED indicators to be tested, even indicators normally on at power up like low oil pressure.

One system runs the 10 second continuous LED cell and the other runs the flashing LED cell. A timer or power failure is indicated by a failure of one or the other LED in each cell. A single LED failure is indicated by only one LED not functioning during self test. One Cell can be configured using a precision voltage reference circuit to indicate low battery voltage. Uses two independent comparator and LED driver circuits for indication redundancy.
