RPM-1 Universal Engine / Rotor RPM Indicator

The RPM-1 is a 2 1/4” sunlight readable color display instrument providing two universal RPM inputs that is primarily intended to measure engine and/or rotor RPM.

The display can be configured to display single or dual RPM or it can be configured to display engine and rotor RPM as used in helicopters and gyroplanes.

The RPM-1 also has a maximum values display screen as well as a handy magneto check function to easy diagnose magneto problems.

The RPM-1 includes a number of timers such as a Hobbs meter which can be set to the current engine time and is also password protected, an engine running and flight timer as well as a programmable maintenance timer to schedule routine engine maintenance.

The RPM-1 can also be interfaced via the CAN bus to an external RDAC unit (Remote Data Acquisition Computer). This allows for easier installation as the RDAC unit is normally mounted in the engine compartment.
