Product Description

PCM is a sealed box that acts as interface module between the autopilot and the rest of the systems of the UAV.

The PCM includes:

  • Servos  power management
  • Data link
  • Engine Monitor (only PCM0X–S version)

Servos power management

PCM can provide up to 12A at factory preset voltage for servos or on-board electronic trough 6 Binder 702 Subminiature M9 – 3 pin connector (IP-67).

 

Data link

Integrated in the box is the data link that enables the communication between the autopilot and the ground station, depending on the configuration there are 3 different datalink options:

  • Telemetry - 900 MHz
  • Telemetry & Video - 2.4 GHz up to 1W
  • Telemetry & Video - 2.4 GHz up to 2W

 

Engine Monitor

The EM can provide any EFIS, autopilot or onboard electronics with 5Hz samples of RPMs, ambient temperature, one cylinder head temperatures (CHT), one exhaust gas temperatures (EGT), one fuel quantity, and total engine-on time.

RPM measurement can be done using optocoupler sensors, hall effect sensors, and inductive pickups. A programmable scaling range allows for multiple pickup pulses per revolution.

Using 6-point characterization curves, the EM can accept the widest variety of resistive, capacitive, differential voltage and thermo-couple sensors. Additionally, its flexible interface can be configured for thermistor or thermocouple CHT sensors.
