1790D-T16BVO Input Base Block Wiring Diagram
For inputs 0…7: For sinking inputs, wire COM 0 (pin 9) to Field Power (-) GND.
For sourcing inputs, wire COM 0 (pin 9) to Field Power (+) 24V dc.
For inputs 8…15: For sinking inputs, wire COM 1 (pin 11) to Field Power (-) GND.
For sourcing inputs, wire COM 1 (pin 11) to Field Power (+) 24V dc.
Note that both COM 0 and COM 1 are internally connected. COM 0 is used for inputs 0…7.
COM 1 is used for inputs 8…15.
1790D-T8BV8V Input/Output Base Block Wiring Diagram
For sinking inputs, wire COM (pin 9) to Field Power (-) GND.
For sourcing inputs, wire COM (pin 9) to Field Power (+) 24V dc.
Note that both COM (pins 9 and 10) are internally connected.
For sinking outputs, wire V dc (pin 11) to Field Power (+) 24V dc, and
wire GND (pin 12) to Field Power (-) GND.
