The SeaI/O-530 modules include 16 optically isolated inputs that are arranged such that each
group of four inputs shares a single common. The four I/O points and shared common are
connected via a five-position removable screw terminal.
The SeaI/O-530 and 540 modules provide 16 or 32 open-collector outputs. The outputs do not
source any current and must be connected to an external power source, max 60VDC, through
the Vin pin locations. Each output acts as a switch and the circuit is open until energized. When
the output circuit is energized in software, the output sinks the current to ground, closing the
circuit.
