Isolated Node Providing Power to the Network
Figure 20 shows a node providing power to the network.
The AC line powers a regulator which provides five (5)
volts locally. The AC line also powers a 24 volt isolated
supply, which powers the network, and another five-volt
regulator, which, in turn, powers the transceiver and iso-
lated (network) side of the two optocouplers. This meth-
od is recommended when there are a limited number of
devices on the network that don’t require much power,
thus eliminating the need for separate power supplies.

More importantly, the unique “dual-inverting” design of
the HCPL-772X/072X ensure the network will not “lock-
up” if either AC line power to the node is lost or the node
powered-off. Specifically, when input power (V
