1. A programmable logic controller comprising:

  • a central processing unit;

    a digital input/output interface operably coupled to said central processing unit, said digital input/output interface having at least one input terminal and at least one output terminal; and

    a micro-electromechanical system (“

    MEMS”

    ) switch connected to each of said at least one input terminal and to each of said at least one output terminal, thereby defining input MEMS switches and output MEMS switches, each MEMS switch having a source connection, a drain connection and gate connection.
