Single Ended Current Inputs (AIN 3 & 4 only)

Single-ended current input mode is useful if the sensor loop is grounded to the WI-I/O 9-
U2 module. Devices can be powered from the 24V Analog Loop Supply (ALS)
generated internally from the module.

The Dip Switches are used to determine if the inputs will be current or voltage.

Dip Switches 1 & 2 are used for or Analog 3 and Dip Switches 3 & 4 are used for
Analog 4

For Current set both Dip Switches to the “On” position, for Voltage set both to “Off”
