Input Block Wiring Diagram
For inputs 0…7: For sinking inputs, wire Com 1 to Field Power (+) 24V dc and Com 0 to Field
Power (-) GND. For sourcing inputs, wire Com 1 to Field Power (-) GND and Com 0 to Field
Power (+) 24V dc.
For inputs 8…15: For sinking inputs, wire Com 3 to Field Power (+) 24V dc and Com 2 to Field
Power (-) GND. For sourcing inputs, wire Com 3 to Field Power (-) GND and Com 2 to Field
Power (+) 24V dc.
Note that all Com 1 and Com 3 are internally connected. Com 1 is used for inputs 0…7.
Com 3 is used for inputs 8…15.
1790D-8BV8V Input/Output Wiring Diagram
For sinking inputs, wire Com 1 to Field Power (+) 24V dc and Com 0 to Field Power (-) GND.
For sourcing inputs, wire Com1 to Field Power (-) GND and Com 0 to Field Power (+) 24V dc.
Note that all Com 1 are internally connected.
For sinking outputs, wire Com 2 to Field Power (+) 24Vdc, and
Com 3 to Field Power (-) GND. Note that all Com 2 are internally connected.
