The Allen-Bradley 1746-OBP8 is a high-performance digital output module designed for the SLC 500 programmable logic controller system. Optimized for demanding industrial environments, this module provides eight sourcing output channels configured in two isolated groups of four. It is specifically built to handle high-current loads, making it an ideal choice for driving heavy-duty actuators, large solenoids, and high-wattage indicators that require more power than standard I/O modules can provide.Features
High Current Capacity: Delivers a continuous 2.0 Amps per point across the full operating temperature range (0 to 60 degC) without thermal derating.
Integrated Diagnostics: Includes e-fuse LED status indicators for each channel, enabling rapid visual fault detection and maintenance.
Isolated Architecture: Outputs are organized into two distinct isolated groups to enhance circuit protection and system flexibility.
Robust Power Handling: Capable of managing a total module current of 8.0 Amps, with a surge current capacity of 4.0 Amps per point for 10 ms.

Installation Guidelines
Power Safety: Always disconnect backplane power before inserting or removing the module from the chassis to prevent electrical damage.
Mounting: Ensure the module is fully seated in the SLC 500 chassis slot and secured with the integrated locking tab.
Wiring: Utilize shielded cabling for output signals to minimize EMI interference, especially when driving inductive loads.
Environment: Maintain adequate clearance around the chassis to ensure proper ventilation and cooling, adhering to the 0 to 60 degC operating range.
Grounding: Follow standard industrial grounding practices for the chassis and power supply to ensure signal integrity and safety.
FAQWhat does the 'P' in 1746-OBP8 stand for? The 'P' designates this module as a high-power output variant, specifically engineered to drive larger electrical loads compared to standard SLC 500 output modules.Does this module require thermal derating? No, the 1746-OBP8 is rated for a continuous 2.0 Amps per point across its entire specified operating temperature range of 0 to 60 degC.
