These digital I/O boards can be supplied in all the different configurations of the original product (with 50-pin D-Sub connector on the front-panel or ribbon-cable connector either on or behind the front-panel, equivalent to the original VMOD-2 and VMOD-2D models of PEP-Kontron). Al mechanical and electrical interfaces are identical to the original VME carrier boards, and on a single board we can implement all the expanded configurations normally obtained by means of the additional piggyback modules. The boards can be manufactured and supplied in the extended temperature range and ruggedized version, and custom solutions can be delivered upon request.
