The SI-DEMO-01 and SI-DEMO-02 programming and training development aids are for use with the Solves-It! line of plug-in PLCs.
Each unit is a compact printed circuit base with nonslip feet that facilitate desktop use. Each board has a prewired 11-pin socket and the appropriate number of input switches and output indicator LEDs for the matching Solves-It! plug-in PLC. A terminal strip lets users bypass the onboard I/O with external inputs and loads and an available pushbutton provides input for the high-speed counter. A Class 2 transformer supplies the unit with 12-Vdc power.
