MMC 32In/32Out Option Module
G & L Motion Control Inc. MMC Hardware Manual 151
When a short circuit or over-current condition is sensed, all outputs
in the group are turned off and remain off for approximately 100 ms
regardless of ladder activity. After 100 ms, the ladder again controls
the outputs. In addition, each output is protected with internal
clamping diodes. Without clamping, high voltage transients
(kickback) from inductive loads might damage the module.
For safety reasons, all outputs turn off (no current flow) when a
scan loss condition occurs.
For more information on DC output operation, refer to Section A.3
on page 173 of Appendix A .
