Base units are moulded from a similar material. Each base unit can be mounted onto
standard DIN rails or directly onto a panel or wall. The moldings incorporate slots and
clamps for DIN rail mountings, and holes for screw fixing.

For each I/O Module there is a matched termination assembly set. The controller
incorporates module polarization keying to ensure they are matched when installed.
Modules have polarized sockets that align and mate with coding pegs located on the
termination assembly. The alignment of the sockets and pegs ensure only the matched
I/O module type can be fitted into each associated termination assembly and only a
processor can be installed on a processor base unit.
