Rockwell Automation 1746-XXXX SLC 500 32-Channel Digital I/O Modules Installation Instructions - Manual (Page 18)

18 SLC 500™ 32-Channel Digital I/O Modules
Publication 1746-IN028A-EN-P - October 2003
Output Module (1746-OB32 and 1746-OB32E)
1746-OB32
5 to 50V dc Transistor Output Sourcing
1746-OB32E
10 to 30V dc Electronically Protected Sourcing
(1) See decimal and octal coding information on page 16.
(2) The V dc and dc Com pins on the 1746-OB32 and 1746-OB32E output module are isolated between the two groups and the
two V dc and two dc Com pins in each group are connected internally.
(3) Both V dc pins must be connected to the dc power source if current for a common group is expected to exceed 2 amps. To
maintain group isolation provided by 32-point I/O modules, use a 1492 terminal block that provides group isolation. Consult
1492 documentation or your Allen-Bradley Sales Office for additional information.
