Module codes of AED404 / AED416 Devices and the Corresponding LF Parameter Channel Numbers

LF Parameter Channel Numbering Rules:

  1. The LF Parameter channel numbering system is based on module codes. In a synchronized multichannel AE diagnostic system formed from AED404 and/or AED416 devices, all LF Parameter channels have different channel number.

  2. All AED416 devices have 8 LF Parameter channels. For any of these devices the starting LF Parameter channel number is: (ModuleCodeAED416 – 1)*16 + 1.

  3. At any AED416 device the lower five LF Parameter channels are inputs for external analogue signals. The higher three LF Parameter channels are fixed for the

    (a) Input Power Supply Voltage, (b) Internal Temperature, (c) Internal Relative Humidity measurement.

  4. All AED404 devices have 4 LF Parameter channels. For any of these devices the starting LF Parameter channel number is: (ModuleCodeAED404 – 1)*4 + 1.

  5. At any AED404 device only the first LF Parameter channel is input for an external analogue signal. The higher three LF Parameter channels are fixed for the

    (a) Input Power Supply Voltage, (b) Internal Temperature, (c) Internal Relative Humidity measurement.
