    105 module are effective. Antenna Installation (105U units only) The 105 module will operate reliably over large distances. The distance which may be reliably achieved will vary with each application - depending on the type and location of antennas, the degree of radio interference, and obstructions (such as hills or trees) to the radio path.

An antenna should be connected to the module via 50 ohm coaxial cable (eg RG58 or RG213) terminated with a male coaxial connector. The higher the antenna is mounted, the greater the transmission range will be, however as the length of coaxial cable increases so do cable losses.
  • Page 11 Chapter Two Installation any gain, then the power transmitted from the antenna will be the same as the power out of the module, and hence will not exceed the permitted power of the unlicensed channel. Dipole antennas should be mounted vertically, at least 1 metre away from a wall or mast for maximum performance.

    Load Max 30VDC 0.5A 105U Digital outputs may be configured to individually turn off if no command message is received to that output for a certain period. This feature provides an intelligent watch dog for each output, so that a communications failure at a transmitting site causes the output to revert to a known state. See Chapter 4 Configuration for further details.

  • Page 18: Analogue Outputs (105-1 And 105-3)

    The use of shielded wiring inside an enclosure containing a 105 module is also recommended. To connect an AI on the 105U to an analogue signal from a PLC or DCS output, check the internal circuit of the output carefully as different devices use different ways to create an analogue signal.
  • Page 19 Chapter Two Installation the loop can be powered be either the 105U or the device. Externally powered loops to 27 VDC may be connected by connecting the output between the "AO” terminal (positive) and the "COM" terminal (negative). Zener protection of analogue outputs provides protection against short periods of over-voltage but longer periods may result in module damage.

  • Page 20: Pulse Input

    Active pulse signals can be connected directly provided the peak voltage is between 3.5–13V and the low voltage is less than 1.5V. Note that the 105U will ground the negative of the pulse signal. If the voltages are not compatible, use a solid state relay to isolate the two devices.

  • Page 21: Pulse Output (105-3 And 105-4)

    Some devices such as PLC counter modules power the pulse loop. For these devices, connect to the PO and COM terminals of the 105U. The COM terminal will connect a ground/earth to the external device. If this is not suitable, use a solid state relay to isolate the external device.
