SeaI/O Manual

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.
