The Tachometer / Deadman Interface Board

 offers a flexible engine/avionics interface that provides ignition control via from the aircraft controller and a manual kill switch. It also provides and a logic level tachometer to the controller. It has been designed to directly interface to the Piccolo autopilot. For more information, see Tach / Deadman's Interface Control Specification.

Key Features:

• Deterministic control of ignition state for both magneto and electronic ignition modules via a single 5-volt level discrete input (typically driven by Piccolo Deadman’s output).
• Conditioning of the incoming RPM signal for sampling by the Piccolo.
• The option for an external (vehicle mounted) engine kill switch and companion status LED. This provides operators manual control over the ignition state regardless of the autopilot commanded state, providing an additional level of safety during ground operations
• The option to power an electronic ignition module directly from the Piccolo Deadman’s 5-volt output or from an external battery or power source.
