1734sc-IF4U Configuration

Note

: The 1734sc-IF4u user manual, which is available online by following the hyperlink on the Vendor tab, provides additional configuration information for some of the parameters discussed in this help file.

Channel Enable

Checking this box disables the configuration selections for the channel. When the box is unchecked, the remaining configuration selections for that channel are enabled. It is unchecked (enabled) by default.

Filter

The input filter selection allows you to select the filter frequency for each channel. Valid options are:

The filter frequency is set to 17 Hz by default.

Open Circuit Response

This selection defines the state of the channel’s data word when an open circuit condition is detected on the corresponding channel. Valid options are:

The default value is Upscale.

Input Type

The Input Type selection indicates the type of input device on the channel. Valid options are:

The default value of the input type is -10 to 10 V.

Note

: Channels configured for RTD3/4 wire or resistance modes must be set up in an adjacent pair (channels 0 and 1, 2 and 3), with the settings for the second channel in the pair exactly matching the first.

Note

: CJC input type is available only for Channel 0.

Note

: Up to three Thermocouple input types can be selected.

Data Format

This selection configures each channel to present analog data in one of the following formats:

The data format is set to Engineering Units X1 by default.

Select 2/3/4-Wire RTD

Select 2/3/4 wire RTD on the associated channel.

The default setting is 3-wire.

Note

: The 2/3/4-Wire RTD selection is only active when the channel’s input type is set to an RTD or resistance mode. Otherwise, the control is inactive and will be grayed out.

Temp Units (°)

The Temp Units parameter sets the temperature units of the channel to either degrees Celsius (C) or degrees Fahrenheit (F). The default is degrees Celsius. This selection is applied to the appropriate channel only if the data format selected is Engineering Units X1 or Engineering Units X10.

Note

: The Temp Units control is only active when the channel’s input type is set to a thermocouple or RTD mode. Otherwise, the control is inactive and will be grayed out.
