Output Power and Communication Signals
The PowerShield communication signals are isolated from its internal circuitry via open collector
opto-coupled transistors. The connection labeled “Signal Return” is a common return point for all
communication signals. In the typical application, the attached equipment digital ground connects to
Signal Return, and pull-up resistors turn the open collector signals into logic levels.
