Optically isolated inputs are arranged such that each group of four shares a single
common. The four I/O points and shared common are connected via a five-position
removable screw terminal. Input voltage range is 5-30VDC. Like the inputs, each
group of four Reed relays also shares a single common and connects via a five-
position removable screw terminal. Form C Relay outputs are arranged such that each
group of two relays shares a common. The NC and NO contacts of each relay along
with the common are brought out via a five-position removable screw terminal.
