Configured for safety output switching in distributed control architectures, the Allen-Bradley 1734-OB8S (1734-OB8S POINT I/O Safety I/O Module) provides direct electrical execution for safety-related field output devices within POINT I/O platforms.

Module Configuration Overview

The Allen-Bradley 1734-OB8S is a POINT I/O safety output module designed for connection to safety control systems requiring distributed digital output functions. The module provides 8 output points with a 24 VDC supply requirement and supports safety-rated output switching applications.

The module uses the POINT I/O modular architecture and integrates with compatible GuardLogix safety controllers through supported communication adapters.

Hardware Specifications

Safety Control and Network Integration Characteristics

The 1734-OB8S is designed for integration into Allen-Bradley safety control architectures using POINT I/O distributed modules. The module supports safety output execution through compatible safety controllers and network adapters.

The POINT I/O platform provides I/O density scaling for compact control cabinet layouts. EtherNet/IP based deterministic networks can be used when the module is installed with compatible communication interfaces.

Safety configuration, controller firmware compatibility, and network adapter revision must match the requirements of the installed safety system. The module operates as part of a configured safety solution rather than as an independent safety controller.
