BRX Analog


Setup BRX Analog Inputs

Depending on which model of BRX CPU, there are 1 to 4 analog input channels located at WX0 through WX3. These channels can be configured to accommodate either Voltage or Current transducers. Each channel can optionally be scaled and the resulting floating point value placed in RX0 through RX3 respectively.

 

 

Analog Input # - selects the input type which will then determine the Range, Resolution, Units / Count, and if required, the location of the Broken Transmitter indication.

Enable Scaling from WX# to RX# - enables the automatic scaling of the raw input value to engineering units.

WX# Min / WX# Max - the minimum and maximum raw values determined by the Analog Input Type selection.

Counts / VDC - displays the WX#'s Min and Max values in terms of the range of counts or the range of volts / milliamps.

RX# Min / RX# Max - minimum and maximum values for the Engineering Units.

Range Limit RX# - if enabled and the calculated scaled value is lower than RX # Min or higher than RX# Max, the specified Min and Max values will be used.

 


Setup BRX Analog Outputs

Depending on which model of BRX CPU, there are 1 or 2 analog output channels located at WY0 through WY1. These channels can be configured to accommodate either Voltage or Current devices. The value for each channel can optionally be scaled from the floating point values in RY0 through RY1 respectively.

Enable Scaling from RY# to WY# - enables the automatic scaling of the value in engineering units to the raw output value.

RY# Min / RY# Max - minimum and maximum values for the Engineering Units.

 

WY# Min / WY# Max - the minimum and maximum raw values determined by the Analog Output Type selection

Counts / VDC - displays the WY#'s Min and Max values in terms of the range of counts or the range of volts / milliamps.

 

Range Limit WY# - if enabled and the calculated scaled value is lower than WY# Min or higher than WY# Max, the specified Min and Max values will be used.
