SDM-CD16D 16 Channel Digital Control Port Expansion Module

Use a screwdriver in either the top or front slot, as appropriate, to open the
terminal spring. Strip any insulation from the wire to give 7 to 9 mm bare wire.
Push the wire into the opening, and, while holding it in position, withdraw the
screwdriver to release the spring. The wire will now be firmly held in place.
See Figure 4, below.

You cannot reliably insert more than one solid-core wire into
one terminal connector unless the wires are soldered or clamped
together. When inserting more than one stranded wire, twist the
bare ends together before insertion.
