RDAC

RDAC

The iEFIS and Extreme offers comprehensive engine monitoring for any engine. All engine data is captured via our RDAC (Remote Data Acquisition Computer) that mounts near the engine (in front of or behind the firewall). This data acquisition computer then sends all sender data to the iBox/iEFIS/XTreme via the CAN Bus Network. No wiring harness for engine senders required!

NEW – RDAC now communicates with select VEGA and BLAZE engine monitoring units for greater ease of installation and the ability to connect multiple instruments to the CAN bus eliminating needless sensor redundancy!

There are 5 RDAC models, depending on your need:

• RDAC XF – All engine functions with 12-channels for thermocouples (CHT/EGT)
• RDAC XF MAP – All engine functions with 12-channels for thermocouples and manifold pressure (MAP)
• NEW – RDAC XG – Lower cost engine monitor with reduced functionality; 8-Channel Thermocouple, Tach, Temperature/Pressure Inputs
• RDAC CAN 912iS – CAN RDAC for Rotax 912/915iS Engine
• RDAC CAN ULP – CAN RDAC for ULPower Injected Engines

Twin engine or extra sensor requirements? You can connect 2 RDACs to each EFIS (except the XTreme).

When Used With iEFIS

Engine functions from RDAC XF:

• RPM x 2
• Hobbs Time
• Tach Time
• Maintenance Timers
• CHT (up to 12 total EGT/CHT)
• EGT (up to 12 total EGT/CHT)
• Oil Temperature
• Oil Pressure
• Fuel Pressure
• Water Temp (if required)
• Carb Temp (if required)
• Fuel level x 2 (with resistive senders)
• Fuel flow x 2 (using fuel flow sensor or fuel injector signal)
• Current sensor input
• Manifold Pressure (RDAC XF MAP)

EGT Lean Assist:
Just press on the EGT bargraph display on the touchscreen at any time and automatic peak detection will be enabled. A graph will begin generating making it easy to spot the first EGT to peak and it will then display lean or rich of peak differential.

Alarms:
When ever any engine parameter is exceeded an alarm will be initiated. The alarm can be setup to be any or all of the following (see the alarm options in the CHT menu at right for all options available in each sender set):

• On screen warning
• iBox Alarm Out External contact (panel master caution light or buzzer)
• Audio voice alert

When Used With XTreme

Engine functions:

• RPM
• Hobbs
• Maintenance Timers
• CHT
• EGT
• Oil Temperature
• Oil Pressure
• Fuel Pressure (if not using NTC CHT inputs)
• Water Temp (if required)
• Carb Temp (if required)
• Fuel level (1 or 2 with resistive senders)
• Fuel flow (using turbine sensor or fuel injector signal)
• Current sensor input (RDAC XF only)

Alarms:
Whenever an engine parameter is exceeded an alarm will be initiated. The alarm can be setup to be any or all of the following:

• On screen warning
• Flashing Enigma alert light
• External contact (panel warning light)
• Voice alert (which you can record yourself using the Sounds program) (not available on XTreme)

RDAC Technical Details:

• Four or twelve channel thermocouple amplifier, high resolution chopper stabilized system with full cold junction compensation and low voltage correction to laboratory standards.
• The inputs can accept K-type or J-type thermocouples (selectable via provided menu functions)
• Oil and Water temperature NTC input compatible with most oil temperature senders and the MGL water temperature sender.
• Also accepts MGL precision semiconductor senders for water and oil temperature.
• Universal rev counter input. Can be used on a wide variety of engines using a variety of interface methods.
• Fuel flow sender input. Can be used with most commercial liquid flow senders. Calibration via provided menu functions. (Dual fuel flow inputs available on XF models)
• Oil pressure sender input. Accepts most commercial oil pressure senders including those from VDO.
• Fuel level sender input with extensive calibration functions provided to allow direct readout of fuel quantity corrected for tank shape and sender tolerances (accurate fuel volume, not level)
• LM335 sensor based temperature sender to indicate ice warning. The sender is normally fitted to the outside of a carburetor, in close proximity to the throttle slider or valve or in the intake airflow.
• The EMS included with the EFIS provides for a wide variety of engines and the display unit can be configured in many different ways to display the information required.
