ABB O3ES HENF445789R1 Switch output module

Three rotary switches and two slide switches located on the side of the module are used to select input and output ranges. Most popular ranges are listed on the module labels. See www.api-usa.com or contact factory for special ranges. 1. Set the INPUT SELECT slide switch to current (I) or voltage (V) depending on input type. The input selector switch determines the input impedance for the module, typically 50 Ω for current inputs and 1 MΩ or greater for voltage inputs

Set the OUTPUT SELECT 

slide switch to current (I) or voltage (V) depending on output type. 3. From the table, find the rotary switch combination that matches your input and output ranges. 4. Set the three rotary switches A, B, and C to the values found in the table. 5. The Zero, Span and Test Range potentiometers can now be adjusted for the desired output range. Depending on the rotary switch settings, the input is filtered, either amplified or attenuated as required, then passed through an optical isolation circuit to the output stage.
