0.75A, < 1 msec)
Fusing
Internal 8A fuse time-lag for each group (Part # 042701994 or

page 639.
External Each group is protected with an 8 A fuse to protect the
module from catastrophic failure. The group fuse is not
guaranteed to protect each output switch for all possible
overload conditions. It is recommended that each point
be fused with a 2 A fuse: Little Fuse 312-002 or
equivalent.
CAUTION
Possible danger to equipment or personnel.
Turn off power to the module and remove the field wiring terminal strip to gain
access to fuses.
