Note
The outputs must be protected by a high-speed, fast-acting 3.15 A 250 VAC fuse.
When mounted in a hazardous area in accordance with the National Electric Code,
a tool must be used to remove the fuse and the area must be designated safe
before the fuse is removed/replaced.
Parameterization of the SM 322; DO x 120/230 VAC/2 A ISOL
A description of the general procedure for parameterizing digital modules can be
found in section 3.3.
Detailed information on the digital output module parameters can be found in
Appendix A.3.
Parameters of the SM 322; DO 8 x 120/230 VAC/2 A ISOL
Table 3-22 shows the settable parameters with the default settings for the SM 322;
DO 8 x 120/230 VAC/2 A ISOL.
The default settings apply if you have not performed parameter assignment in
STEP 7.
