Figure 5-8: Eclipse Omega Matrix’s Double-Pole Double-Throw Alarm Relay
GENERAL-PURPOSE OUTPUTS CONNECTOR (GP OUT)
The DB-25 connector labeled “GP OUT” connects the matrix to eight
double-pole double-throw (DPDT) relays with contact ratings of 30 VDC at 1A.
Each general-purpose output has a relay inside the Eclipse Omega matrix. When
a general-purpose output is inactive, the associated “common” pin on the GP
OUT connector will be shorted to the relevant “normally closed” pin. When a
general-purpose output becomes active, the short between the “common” pin is
broken and a new connection is made between the “common” pin and the
“normally open” pin.
