Isolated Node Providing Power to the Network
Figure 21 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 transceiv-
er and isolated (network) side of the two optocouplers.
This method 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-x710 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
the HCPL-x710 located in the transmit path is eliminat-
ed, a RECESSIVE bus state is ensured as the HCPL-x710
