• 16 bit ISA-bus-board • 16 digital outputs (High-Side Power Switching)• Each digital output has its own PWM (Pulse Width
Modulation)• The basis board can be individually adapted for various
applications– via piggy packs
– via firmware updates (per download to SE²PROM (serial E²PROM))
– via download from internet

• For AquaPro: measure the quantity of fluid flowing through a counting flow meter
• Alternate possibilities (in discussion):– get analog/digital feedback signals
• feedback actuator actual signals• detect zero-voltage-transition points and thereby enable a
phase control circuit• ...
