The
Channels
 page (5094-IRT8S, 5094-IRT8SXT) includes these parameters:
Parameter
Description
Channel
The channel number to which this configuration applies.
Disable
Select to disable channel configuration or clear to enable channel configuration.
Disable the channel to help prevent erroneous fault reporting, such as open wire fault, and to help prevent the FLT LED for that channel from illuminating.
Input Type
Select the input type for the channel. Available options are:
  • RTD
  • Thermocouple
Sensor Type
Select the sensor type corresponding to the
Input Type
(RTD or Thermocouple).
Input Range
Select the input range for the sensor type. Ranges vary according to the selected
Sensor Type
.
Notch Filter
Select the notch filter value, which attenuates the input signal at the specified frequency. Notch filter is based on what noise frequencies are present in the module’s operating environment versus any speed requirements needed for control.
Digital Filter (ms)
Enter the time constant for a first order lag filter used to smooth noise transients on the input with a range from 0…32767 milliseconds. When set to 0, no filtering takes place.
Disable Alarms
Select to disable the module from generating process alarms or rate alarms. Clear to enable the module to generate process alarms or rate alarms.
Diagnostics
Select to open the
Ch0x Diagnostics
 dialog box and view diagnostic information.

Select to turn on
Latch fault until reset via output tag
 or clear to turn off

 for all channels.
  • Selected: The I/O channel holds safety input fault indications until it checks if a fault exists. If the fault is removed, the channel only clears the fault status after detecting that the ResetFault, in the channel consume assembly, has a rising edge. Otherwise, the channel continues to check if a fault exists.
  • Cleared: The I/O channel holds safety input fault indications for one second before checking if a fault exists. If the fault is removed, the channel clears the fault status. Otherwise, the channel continues to check if a fault exists.
