4.2.2 Wiring Principle of Output Interface
The system output interface is the source output, and the system output signal all provided by the
Darlington Transistor(DT) after insulated, when the output is active, the corresponding DT conducting. When the
output signal is low level, the external 24V power (such as relays) should be with the common ground with the
system 24V. The Fig. is the external output wiring diagram.
