SeaI/O Manual 94
The SeaI/O-470 modules include eight 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-470 modules provide eight open-collector digital outputs. The outputs do not
source any current and must be connected to an external power source, max 30VDC. The
outputs act 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.
