The WD-55 is a versatile, self-contained digital timer/ controller/sequencer designed to replace many of the timing and control functions currently being performed by gears, cams, levers, and motors.
It is another in a series of "silicon software" preprogrammed microcontrollers based on the WD40 family of 4-bit microprocessors.
The WD-55 may be used in conjunction with a matrix keyboard and numeric display to implement a programmable timer/sequencer or with suitable "strap" options, may be used as a dedicated, standalone on/off controller.
