If an output module fuse blows repeatedly, a probable cause may be:

A) the module's output current is being exceeded.
B) the output device may be shorted.
C) the output field wiring may be shorted.
D) any one of these.

Output Module Fuse

A safety device in an output module of a PLC or control system designed to protect the module and connected devices from overcurrent by breaking the circuit if the current exceeds a certain threshold.

Output Device

Any connected equipment that will receive information or instructions from the central processing unit, such as control devices (e.g., motors, solenoids, alarms) or peripheral devices (e.g., line printers, disk drives, displays). Each type of output device has a unique interface to the processor.
