4.6 Supply Voltage
The supply voltage may be mapped as an internal analog input. The 16 bit value corresponds to
0-30V. There is no analog sensitivity for this measurement - it is only transmitted based on the
configured update time. The measurement is taken every time the WI-I/O K transmitter operates.
The supply voltage also has user-configurable setpoints to determine the Supply Low Volts
alarm. These setpoints can be set from the SetPoint option. The WI-I/O K module will shut-
down when the supply voltage reaches 90% of the “low volts” value. We recommend the
following setpoint values:
Battery Type Low Volts Setpoint Shut-down Voltage
WI-BP-I/O-9-K Battery Pack 6.0 5.4
12V “Gell-cell” 11.2 10.0
