Connecting Wiring for the 1794-IB16D Module (using a 1794-TB32 or 1794-TB32S Terminal Base) 1. Connect individual input wiring (IN00-IN15) to terminals 0 thru 15 on the 0-15 row (A) as indicated in the Wiring Connections for 1794-IB16D table. 2. Connect individual Sensor Power wiring (sensor power 0...15) to terminals 17...32 on the 16-33 row (B) as indicated in the Wiring Connections for 1794-IB16D table. Do not connect to terminals 16 or 33. 3. Connect the associated +V2 DC power lead of the input device to the corresponding terminal on the 34-51 row (C) for each input as indicated in the Wiring Connections for 1794-IB16D table. (The +V2 power terminals of row (C) are internally connected together.) 4. Connect the associated input common (3-wire devices only) to the corresponding terminal on the 34-51 row. (C) for each input as indicated in the Wiring Connections for 1794-IB16D table. (Commons are internally connected together.) 5. Connect +V DC power to pin 43 (+V) on the 34-51 row (C). 6. Connect -V DC common to pin 44 (COM2) on the 34-51 row (C). 7. If daisychaining input wiring power to the next terminal base, connect a jumper from terminal 49 (+V DC) on this base unit to the power terminal on the next base unit (refer to the installation instructions for the next terminal base unit). 8. If continuing input wiring common to the next base unit, connect a jumper from terminal 50 (common) on this base unit to the common terminal on the next base unit (refer to the installation instructions for the next terminal base unit).

Connecting Wiring for the 1794-OB16D Module (using a 1794-TB2, 1794-TB3, or 1794-TB3S Terminal Base) 1. Connect individual output wiring to numbered terminals on the 0-15 row (A) as indicated in the Wiring Connections for 1794-OB16D table. 2. Connect the associated common for each output to the corresponding terminal on the 16-33 row (B) as indicated in the Wiring Connections for 1794-OB16D table. (The common terminals of row (B) are internally connected together.) 3. Connect +V DC power to terminal 34 on the 34-51 row (C). (The power terminals of row (C) are internally connected together.) 4. Connect DC common (COM) to terminal 16 on the 16-33 row (B). 5. If daisychaining power to the next terminal base, connect a jumper from terminal 51 (+V DC) on this base unit to terminal 34 on the next base unit. 6. If continuing DC common to the next base unit, connect a jumper from terminal 33 (common) on this base unit to terminal 16 on the next base unit.
