Selection Notes

This is the push-in counterpart to the screw-terminal 32-channel module: the same four 16-pole IDC connectors and 8-terminal potential feed, but conductors clamp in without a screwdriver, sized for 0.5-1.5 mm² stranded wire. That narrower cross-section range versus the screw version trades some conductor flexibility for faster panel assembly. Choose it when the cabinet's termination standard is push-in throughout rather than mixed with screw terminals.
