Units Description Definition
6 Signed Ana-
log, 0 to 20
mA
For a signed value, such as temperature, that is to be converted to a mA out value. Use null to
set the start point and span to define the range. The null value is the starting temperature to
be associated with 0 mA. The span is the entire temperature range that is to be associated with
0 to 20 mA.
LCD: 0.00mA–20.00mA
7 Unsigned Ana-
log, 0 to 20
mA
For unsigned values, such as a counter, 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 associ-
ated with 0 mA. The span is the entire distance range that is to be associated with 0 to 20 mA.
LCD: 0.00mA–20.00mA
8 Signed Ana-
log, 4 to 20
mA (A)
In older models, this units type is for degree Celsius 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
9 Signed Ana-
log, 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 asso-
ciated 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 associ-
ated 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
5.9.1 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), humidity (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 tempera-
ture readings are stored as signed numbers (two's complement).
The following table defines the range of values and descriptions for input units.
