2.2.3 Internal I/O
The internal supply voltages can be monitored by reading the register locations below.
See Section 5.1 “IO Diagnostics” for details on how this can be done.
The values can also be mapped to a register or an analog output on another module
within the radio network.
30005 Local Supply voltage (0-40V scaling)
30006 Local 24V loop voltage (0-40V scaling) – Internally generated +24V
supply used for analog loop supply. Maximum Current limit is 100mA
30007 Local Battery voltage (0-40V scaling)
30008 WI-I/O-EX-1-S Supply Voltage (0-40V scaling)
38005 – 38008 Floating Point Registers, also indicate the Supply voltage, Battery
Voltage, +24V Supply and WI-I/O-EX-1-S Supply voltages but in a
voltage scale.
To calculate the supply voltages from the register value use the following calculation
There are no dedicated discrete low voltage alarm indicators however each supply
voltage does have a High and a low Set point Status which can be used for this type of
alarm.
See section 4.3.9 “Analog Inputs” for details on how to configure these alarms.
2.2.4 Grounding
To provide maximum surge and lightning protection each module should be effectively
earthed / grounded via a "GND" terminal on the module – this is to ensure that the
surge protection circuits inside the module are effective. The module should be
connected to the same common ground or earth point as the enclosure “earth” and the
antenna mast “earth”.
The WI-I/O 9-U2 has a dedicated Earth connection screw on the bottom end plate next
to the Supply terminals. All EARTH wiring should be minimum 2mm² - 14 AWG
If using the WI-I/O 9-U2 with serial Expansion I/O modules then all expansion modules
must have a separate earth connection from the front terminal back to the common
earth or ground point. See Figure 5 - Earthing below
