Units Description Definition
9 Signed Analog,
4 to 20 mA (B) In older models, this units type is for degree Fahrenheit conversions only. Use null to set the start point and
span to define the range. The null value is the starting temperature to be associated with 4 mA. The span
is the entire temperature range that is to be associated with 4 to 20 mA. For newer firmware models, type
codes 8 and 9 are treated the same.
LCD: 4.00mA–20.00mA
10 Unsigned Ana-
log, 0 to 10V For an unsigned value, such as 0 to 20 mA, that is to be converted to a voltage out value. Use the null to
set the start point and span to define the range. The null value is the distance to be associated with 0V.
The span is the entire distance range that is to be associated with 0 to 10V.
LCD: 0.00V–10.00V
11 Counter, 16-bit The 16-bit counter value records counts up to 65535.
LCD: 0000
12 Unsigned Ana-
log, 4 to 20 mA For an unsigned value, such as 0 to 10V, that is to be converted to a mA out value. Use the null to set the
start point and span to define the range. The null value is the distance to be associated with 4 mA. The
span is the entire distance range that is to be associated with 4 to 20 mA.
LCD: 4.00mA–20.00mA
Interpreting Register Values in the Banner Wireless System
The units conversion table defines the type and range of values for each type of I/O.
The wireless devices have many different units of measure for inputs including: milliamp (mA), voltage (V), temperature (°C or °F), hu-
midity (RH), or a raw 16-bit or 32-bit value. Outputs can be either current (4–20 mA, 0–20 mA) or voltage (0–10V dc). All values stored in
Modbus registers are unsigned numbers, except for temperature readings. The temperature readings are stored as signed numbers
(two's complement).
The following table defines the range of values and descriptions for input units.
