Output Configuration

The input must be configured before selecting the output configuration.
Set the Output Jumpers
For voltage output signal type set the output jumpers to the VOLT (0-20 volt) and SOURCE positions.
For sourcing current output signal type set the output jumpers to the mA (0-20 mA) and SOURCE position. For sinking output current signal type, set the
output jumpers to the VOLT and SINK positions.
The NORM/REV jumper should remain set in the NORM position until all other settings are made. If, for example, a 5-0 volt output is required then set up
the device for a 0-5 volt output and then change the jumper to the REV position.
Figure 8 0-Output Jumper Settings.
Set the Output DIP Switches
If the required preset output signal type is listed in the table below, then set the 8 switches according to the chart and the output will be correctly calibrated
for that signal type. For example, if the output signal is 4-20 mA, then set switches 4, 5, 6, and 8 ON and all others OFF and the input will be correctly
calibrated for the 4-20 mA output range.
Figure 9 0-Output DIP Switches Settings.
If the required output signal is not listed in the chart above, then one of the preset offset/span ranges could be used. Check the output signal requirements
as follows; OFFSET = the minimum signal output, SPAN = maximum signal output minus minimum signal output. For example, if the output signal is to be
0-7 volts, then OFFSET = 0 V and SPAN = 7 V. Once these two values are determined check the following charts for the available presets for offset and
span.
Select a Preset Output Offset
If the OFFSET is 0, 1, or 2 volts or 0, 4, or 8 mA, then set the output DIP switches according to the following chart. Switches 5 and 8 will be set later for
the SPAN.
Figure 10 0-Preset Output Offset Settings.
Select an Adjustable Output Offset
If the required OFFSET is not equal to one of the preset values in the above chart, then select the adjustable offset as shown in the following chart. An
example of this would be if the output signal is to be 3-15 volts, then OFFSET = 3 V and SPAN = 12V.
