Figure 7-10: 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.
