3.4. Digital Outputs [-EB1]
Optically-isolated solid-state relays drive the digital outputs. You can connect the digital outputs in
current sourcing or current sinking mode but you must connect all four outputs in a port in the same
configuration. Refer to
and
The digital outputs are not designed for high-voltage isolation applications and they should only be
used with ground-referenced circuits.
You must install suppression diodes on digital outputs that drive relays or other inductive devices. To
see an example of a current sourcing output that has diode suppression, refer to
. To see
an example of a current sinking output that has diode suppression, refer to
The digital outputs have overload protection. They will resume normal operation when the overload
is removed.
