I/O Modules
35013379 11/2011 683
Fault Detection
Input None
Output Blown fuse detect, loss of field power
Bus Current Required (Module) 330 mA
Power Dissipation 1.75 W + 0.36 x input points on + 1.1 V x total
outputs load currents
External Power (Module) Not required for this module
Fusing
Input Internal – None
External – User discretion
Output Internal - 5 A fuse for each group
(Part # 043502405 or equivalent). For the
location of the fuses, (see page 684).
External - Each group is protected with a 5 A
fuse to protect the module from catastrophic
failure. The group fuse is not guaranteed to
protect each output for all possible overload
conditions. It is recommended that each
point be fused with a 1.25 A fuse, Part #
043508930 (Littlefuse 3121.25, 1.25 A, 250
V).
CAUTION
Possible injury to personnel or equipment.
Turn off power to the module and remove the field wiring terminal strip to gain
access to fuses.
Failure to follow these instructions can result in injury or equipment damage.
