10.4 Power Distribution
Figure 48 shows the power distribution on the Relay Card.
Figure 48. Relay Card Power Distribution
The relay coil actuation voltage is 12 V, and so
should be 12 V to 30 V DC. The
+V_USER
supply passes through a linear regulator and comparator, which are in parallel.
+V_USER
The comparator is set for approximately +13.9 V, and as long as
is more than
+V_USER
+13.9 V, the +12 V from the linear regulator will provide the coil actuation voltage.
Should
+V_USER
be less than +13.9 V, the comparator will supply
+V_USER
directly to
provide the coil actuation voltage.
