Engine Monitoring Modules

Providing the interface between a SkyView Display and the engine and aircraft sensors.

The EMS module receives signals from engine sensors for display on your EFIS. Order the SV-EMS-220 for most engines, SV-EMS-221 for the Rotax 912 iS / 915 iS only. Engine sensor/ harness packages for Lycoming/Continental/Jabiru/Rotax engines sold separately. Sensors/ harnesses available a-la-carte for other engines. Two modules can be used to monitor dual engines or to provide up to 28 EGT and CHT inputs for large engines (SkyView only).

Rotax 912 iS / 915 iS: The SV-EMS-221 is designed to support the fuel injected Rotax 912 iS / 915 iS. It receives many engine parameters directly from the 912 iS / 915 iS engine computers via a dual-channel CAN bus interface. Engine parameters available from the 912 iS / 915 iS engine computer include RPM, manifold pressure, oil pressure, oil temperature, coolant temperature, EGT for all four cylinders, ECU voltage, and engine hours. All the other normal SkyView SV-engine functions are still available through regular connections, including fuel level, trim position, battery voltage, and contacts. The SV-EMA-221 replaces the SV-EMS-220 - both cannot be used with the same engine.

Flexibility: The SkyView System is highly configurable for you to design the exact Engine Monitoring display you want. Common engine configurations come standard, but an easy to use setup menu allows you to choose exactly which sensors, displays, ranges and alarms you want.

Some of the parameters you can measure with the SkyView EMS include:

Tach
Manifold Pressure
Oil Pressure
Oil Temperature
Fuel Flow with Fuel Computer
Fuel Pressure
CHT
EGT
Voltage
Current
Fuel Computer
Engine and Flight Timers (It also can monitor discrete sensors for):
- Trim Position
- Flap Position
- And other aircraft parameters

Mounting: The SV-EMS-22X is nominally mounted in the avionics bay near the firewall. NOTE: it cannot be mounted on the engine side of the firewall.

Connections: The SV-EMS-220 has two connectors, a D37 and a D25. The D37 contains dedicated RPM, Voltage, Fuel Flow, Current, MAP, general purpose inputs, and two thermocouple inputs (for extra CHTs and EGTs). The D25 has twelve thermocouple temperature inputs for EGTs and CHTs). The EMS Module is connected to a SkyView Display via a D9 connector.

Engine Sensor Kits: The SV-EMS-220 can use the Dynon Engine Sensor Kits for the 4 and 6 cylinder Lycoming, Continental, Jabiru, and carbureted Rotax engines. The Wiring Harnesses supplied with these kits fit the SV-EMS-220 connectors. There is also a kit for the Rotax 912 iS / 915 iS. Other engines are supported, although the installer will have to determine the correct sensors and wiring to connect to the EMS Module.

Twin Engine / More than Six Cylinders: A second EMS module can be used to monitor a second engine in twin aircraft applications. Or, you can use a second EMS module to add more EGT, CHT, and other inputs to allow full monitoring of complex powerplants or large radial engines.

Design Considerations: A SkyView Network Cable is used to connect an ADAHRS Module to a Display. One SV-EMS-22X will provide data to as many displays as are connected in the SkyView System. Please see our Current & Future Features List for a complete list of current and planned SkyView features.
