The UI current loop jumpers are on the circuit board under the expansion module cover near the UI terminals (Figure 1). When a UI is defined (in the system software) as a 4-20 mA Analog Input, set the UI's current loop jumper to the Enabled position (Figure 1).
Setting the current loop jumper to the Enabled position, connects an internal 100 ohm resistor across the UI terminals, which maintains the 4-20 mA current loop circuit even when power to the expansion module is interrupted or off.
The following tables identify the current loop switches associated with each UI on the XPM09090 and XPM04060 models.
