• 16 port expander for our OS 2.3 sprinkler controller. It uses 2 74hc595 shift registers for output control. As it uses standard shift registers the board can be purposed for other uses.
  Output drive transistor or triac will dictate which valves it controls. Common power rail is not connected to ground plane and can be connected to current sense resistor on control board for sensing power usage
  
  NOT compatible with OS 3.2 as it uses I2C controller chip
