Isolated Digital Output Connection
A digital output channel sends a signal through a galvanic isolator to control the ON/
OFF state of a MOSFET switch. The state of the MOSFET switch then decides if the
load is conducting or not. The universal digital output channel supports both sink
(NPN) type and source (PNP) type connection as shown in Figure 2.3.
Figure 2.3 Digital output signal connection.
For a sink type digital output, the current which flows through the load is sunk by the
digital output (DO) terminal, and returns to the external source through the digital out
-
put ground (DOGND) terminal. This is shown in Figure 2.4.
