SV-EMS-220 Installation and Configurationin aircraft installations, which are primarily resistive in nature. Sensors and transducers includecontacts, fuel level, fluid pressure, fluid temperature, temperature, and positionpotentiometers. For example, SV-EMS-220 DB37 pin 4 can be configured to read a resistive oiltemperature sensor.Sensor and transducer compatibility level B denotes that an SV-EMS-220 DB37 pin labeled as“B” in Table 15 can be configured to support every sensor and transducer listed for “A” whilealso being compatible with a 4 to 20 mA constant current source output sensor.Sensor and transducer compatibility level C denotes that an SV-EMS-220 DB37 pin labeled as“C” in Table 15 can be configured to support every transducer and sensor listed for “A” whilealso being compatible with senders that employ active voltage output hardware includingDynon’s Capacitance-to-Voltage Converter.If an SV-EMS-220 pin’s sensor config space is blank in Table 15, that means that pin has fixedfunctionality. This functionality is described under the Function column in the table.Sensor and TransducerCompatibility LevelABCExample sensors and transducersContactsFuel Level (resistive)0-150 PSI Fluid Pressure (100411-002)1/8”-27 NPT Fluid Temperature (100409-001)5/8”-18 NPT Fluid Temp (100409-000)0-30 PSI Fluid Pressure (100411-000)0-80 PSI Fluid Pressure (100411-001)Jabiru Oil TemperatureJabiru Oil PressureDynon 2-Wire OAT Probe (100433-003)Dynon 2-wire Carburetor Temperature (100468-000)GRT Oil PressureGRT Oil TemperatureRotax CHT or Oil Temperature (801-10-1)Flap/Trim PositionEverything in A, plus can be connected to a 4 to 20 mA current sourcesender (e.g., Rotax P/N 956413 oil pressure sensor)Everything in A, plus Dynon’s Capacitance-to-Voltage Converter andother senders with active voltage output hardwareTable 14–Sensor and Transducer Compatibility Level KeyFuture firmware updates may expand the scope of the compatibility levels listed in Table 14.The tables on the following pages specify the sensor and transducer types that are supportedby each pin on the male DB37 and female DB25 SV-EMS-220 connectors and the wire harnesswire colors. Note that the only purpose of the 25-pin SV-EMS-220 wire harness is forthermocouple connections.
