DYNA 70025 Controllers (Stanadyne)
The Barber Colman DYN1-1078 controller for the DYNC 70025 actuator is an isochronous, solid state design, resulting in fast, stable engine response to speed or load changes. The controller circuits measure proportional (amount of offspeed), integral (time of offspeed) and derivative (rate of change of offspeed) to ensure optimum performance. Models DYN1-1079 add a remote speed function.
The controller electronics are environmentally potted providing protection against the various liquids and vibrations associated with engines. This makes the unit suitable for panel or engine mounting. It is easy to adjust, having only SPEED and GAIN adjustments.
Barber Colman (now Woodward) later developed a digital engine controller, DPG-2104, which can be used as very cost effective drop-in replacement to all DYN1-1078 controllers.
