The E-Board from Pneumadyne Inc., Plymouth, Minn. (pneumadyne.com), lets designers connect 6, 12, or 24-Vdc controller signals to actuate up to 16 solenoid valves. The valves can be 10 or 15 mm. There are also terminals for an auxiliary power supply and threeposition power selectors for each valve. Plug-in fasteners connect each valve, but standoff and DIN-rail clips are optional. A quick-connect bar lets technicians attach or remove up to eight tubing lines with the turn of a thumbscrew.
