PRODUCT INFORMATION
Product Overview
The Allen-Bradley 1746-OBP16 is an SLC 500 High Current Sourcing DC Output Module. This discrete module provides 16 sourcing output channels. It occupies a single slot of an SLC 500 chassis. The hardware operates within fixed or modular style chassis assemblies. It supplies 24 V DC nominal output voltage across a range of 20.4 to 26.4 V DC.
Each channel features an integrated fuse for short-circuit and overload protection. Electronic protection operates independently on each channel. Other channels continue operating if a single channel experiences a fault shutdown. Recovering a faulted channel requires removing SLC 500 system power. Once the fault is corrected, reapplying power resets the module automatically. This behavior must be integrated into fail-safe operating conditions.
