Module Properties dialog box - Ch0x page parameters (5094-IRT8S, 5094-IRT8SXT)
The
Ch0x
page (5094-IRT8S, 5094-IRT8SXT) includes the following parameters:Parameter | Description |
Disable Channel | 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:
|
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 . |
Temperature Units | Select the temperature unit for sensor type. |
10 ohms Copper Offset | For an RTD input type with the Sensor Type set to 10 Ohm Copper 427 , sets an offset value that is within the range from -1.00 through 1.00 Ohms. This value can compensate for any Copper RTD errors and is added to the input reading before linearization. |
Disable CJ Channel | Select to disable CJ Channel or clear to enable CJ Channel. If selected, the CJ sensor offset value appears. |
CJ Sensor Offset | User-defined offset in engineering units that is added directly into the scaled data, The CJ Sensor Offset is used to compensate for inherent sensor offset, and is commonly used with thermocouple sensors to address accuracy issues. |
Engineering Units | Enter the unit of measure used for the channel. |
High Signal | Enter one of four points used in scaling. The high signal is in terms of the channel signal units and corresponds to the high engineering term when scaled. The scaling equation is used. High Signal values must be greater than Low Signal values. |
High Engineering | Enter one of four points used in scaling. The high engineering helps determines the engineering units the signal values scale into. The high engineering term corresponds to the high signal value. The scaling equation is used. |
Low Signal | Enter one of four points used in scaling. The low signal is in terms of the channel signal units and corresponds to the low engineering term when scaled. The scaling equation is used. |
Low Engineering | Enter one of four points used in scaling. The low engineering helps determines the engineering units the signal values scale into. The low engineering term corresponds to the low signal value. The scaling equation is used. |
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. |
Input Value during Open Wire | Select the value to report when open wire condition occurs. Choose between Maximum Engineering or Minimum Engineering. |
Maximum Engineering | Maximum Engineering value at controller input tag when input open wire is detected based on user configuration. |
Minimum Engineering | Minimum Engineering value at controller input tag when input open wire is detected based on user configuration. |
Diagnostics | Select to open the Ch0x Diagnostics dialog box and view diagnostic information. |
