Feature Description Example
Thermocouple
setpoint
This setpoint is associated with the thermocouple input and can also
be configured to read millivolt values.
You can select one of ten different low setpoint/high setpoint pairs
by changing the position of the rotary switch on the front panel of
the WI-I/O 9-L-T module. Alternatively you can set the thermocouple
setpoint threshold values to single values independent of the rotary
switch position by selecting the Single tab.
NO indicates the switch position for this setpoint setting.
Low SP and High SP are the low and high threshold values.
You can also show the values of the high and low setpoints in
different formats by setting the Units field to:
• Raw - data format used by Weidmuller, Inc. units for
transferring analog values.
For millivolt measurement, 16384 corresponds to zero millivolts,
or 0% reading; 49152 corresponds to 100 millivolts or 100%
reading
For temperature measurement, 16384 corresponds to the
bottom of the thermocouple range; 49152 corresponds to the top
of the thermocouple range.
• mA –actual milliamp value that would be output if the
thermocouple input was sent to a 4-20 mA output. (Not normally
used for thermocouple input).
• % - percentage of full scale, with minimum value being 0%
and maximum value being 100%.
For more information, see Selecting thermocouple tables on
page 77.
Temperature
setpoint
This setpoint is associated with the module’s internal temperature
measurement.
The setpoint comes on when the module temperature moves below
the low setpoint, and will go off when the module temperature
moves above the high setpoint.
Battery
setpoint
This setpoint is associated with the module’s supply voltage
monitoring.
The setpoint turns on when the supply voltage falls below the low
setpoint, and turns off when the supply voltage moves above the
high setpoint.
