Earlier generation gun control units or fire control units came in a variety of shapes and sizes, though they typically shared certain characteristics. These systems tended to be large, heavy, and overly complex. Some GCU's, consisting of multiple 'black boxes', could weigh more than 20 pounds. Designed with sensitive electronics, they could easily burn-up, leaving a gun unable to fire.
Complexity was another serious shortcoming. In the event of a failure, it was unlikely that the unit could be returned to service without a trip to depot level maintenance. Typically, unit replacement cost was always high, and the sensitive nature of these early systems meant a large number of spares were necessary.
Dillon Aero's Gun Control Unit is a simple, yet highly robust system. The GCU controls all of the weapon's functions. When either of the twin triggers is depressed the GCU performs the following actions:
- Power is delivered to the Gun Drive Motor.
- Power is delivered to the Clutch, which in turn engages the Feeder/Delinker system.
- Power is delivered to the ammunition Booster Motor.
- The 'Time Delay Circuit' is energized.
When the GCU trigger is released, power is removed from the weapon. The DAC3000 Clutch disengages and the flow of ammunition to the gun is interrupted. After the Clutch disengages the Time Delay Circuit continues to supply power to the gun motor long enough to ensure that all remaining live rounds have been fired. There are no live rounds left in the gun.
- Currently in Service with US and foreign military.
- Dual Firing Triggers provide redundancy.
- Guarded Master Power Switch.
- Night Vision Compatible.
- Optional Integrated 'Intercom System' switch available.
Dillon's GCU is an integral part of the gun, housed in Spade Grips.
