UI current loop jumpers - Facility Explorer - CH-PCA3613 - Field Device - FX-PCA36 Advanced Application Programmable Controller

The UI current loop jumpers are located on the circuit board under the controller cover near the UI terminals. 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 as in Figure 1.

Figure 1. Current loop jumper positions

Setting the current loop jumper to the Enabled position connects an internal 100 ohms resistor across the UI terminals, which maintains the 4–20 mA current loop circuit even when power to the controller is interrupted or off.

The following table identifies the current loop switches associated with each UI on the controller.
