Wire size for Flexslice I/O modules
Trio's Flexslice modules use the a 10-way 3.5mm pitch, push fit connector:
15EDGKN-3.5-10P-13 from Degson.
According
to the manufacturer's datasheets (https://www.tme.eu/Document/580c900c7460c0af0ff973aec46ec4f5/15edgk.pdf)
the maximum wire size is 28-16AWG or 0.5-1.5mm2. The advice is
either to use solid core wire, or, if multi stranded is required, to put a
ferrule on the end. Clearly this ferrule will add to the diameter of the wire,
so the diameter of the ferrule pin once the ferrule has been crimped needs to be
considered.
