Standard MTL backplanes are available to accommodate 4, 8, 16, or 24 modules using screw-clamp connectors for the safe-area circuits.
On an individual backplane, any module can be plugged into any position and module types can be mixed. For 8-, 16- and 24-way
backplanes, screw-clamp connectors which plug into the backplanes provide primary and secondary 24V dc power supplies.
