I/O Module Installation and Wiring - I/O Terminal Block Wiring Diagrams
Jumper Comb
Two-position jumper combs are available (as an option for barrier style terminal blocks only) for
connecting digital common wiring between terminals 10 and 12, and for connecting +24Vdc between
terminals 9 and 11. See Figure 57.
+V Terminals
The +V1 (terminal 9) and +V2 (terminal 11) are the positive power supply input to power the output
circuits for the two groups of eight inputs per group. The +V supply must provide minimum 24 Vdc at 65
mA (min) per group.
Hazardous voltages exist at terminal blocks.
•
Using switches at field devices disconnect the field wiring from power sources before servicing.
Failure to comply with these instructions could result in death or serious injury.
