Repair Allen-Bradley 1746-OB16 SLC 500 Current Sourcing DC Output Module

The Allen-Bradley 1746-OB16 SLC 500 Current Sourcing DC Output Module provides a signal ON delay of 0.1ms and a signal OFF delay of 1ms on a maximum resistive load, and has a 1mA maximum off-state leakage current. 

The module features protection against current overload and short circuit conditions, based on a thermal cut-out principle: the module will limit current on a channel once the temperature threshold is reached on any channel in which a short circuit or overload occurs. Channels without overload or short circuit conditions will continue operating normally. This protection is not intended to replace standard protection devices such as fuses or circuit breakers.

The module also supports auto-reset of channels on which current has been limited after an overload or short circuit. The E-Fuse LED on the module's front panel lights up when an overload or short circuit occurs.
