Figure 18 AI 1 & 2 Single-ended Current Inputs
Single-ended current input mode is useful if the sensor loop is grounded to the 915U-2 module. Devices can be
powered from the 24V analog loop supply (ALS) generated internally from the module.
The DIP switches (located in the side access panel) are used to determine if the inputs will be current or voltage.
DIP switches 1 and 2 are used for analog 3, and DIP switches 3 and 4 are used for analog 4. For current, set both
DIP switches to the “on” position. For voltage, set both to “off.”
