3.4 Isolated Digital Output Connections
The MIC-3756 has 32 isolated digital output channels designated
DO00~DO31.
Power On Configuration
Once the power is on, the default configuration will be when the
hardware resets all the isolated output channels to off status (the
current of the load can’t be sink) so users need not worry about
damaging external devices during system startup or reset.
When the system resets, the status of isolated digital output channels
are selected by jumper JP3.
Table 3-2
shows the configuration of
jumper JP3.

Isolated Outputs
Each isolated output channels come equipped with a Darlington
transistor. Every 16 output channels share common collectors and
integral suppression diodes for inductive loads.
Note:
If an external voltage (5 ~ 40 VDC ) is applied to an isolated output
