Allen-Bradley 1734-OB8S Point I/O 8 Channel Safety Sourcing Output Module 1734OB8S

Description:

The Allen-Bradley 1734-OB8S is an 8-channel safety sourcing output module designed for POINT I/O Guard I/O systems to control safety-related field devices within Logix-based safety architectures. It provides safety-rated 24V DC sourcing outputs for actuators such as safety contactors and control relays, ensuring compliance with functional safety requirements. Commonly installed in machine safety panels, robotic cells, packaging equipment, and automated production lines, this module supports distributed safety I/O deployment. Maintenance teams and system integrators use this module for safety system expansion, machine retrofits, compliance upgrades, and replacement of existing safety output modules in industrial automation environments.

Applications:

The 1734-OB8S safety output module is used to control safety contactors, shutdown circuits, and other safety actuated devices in POINT I/O systems connected to GuardLogix or Compact GuardLogix controllers. It is widely applied in manufacturing facilities, assembly lines, material handling systems, and process equipment where controlled safety outputs are required to achieve safe torque off, emergency shutdown, and protective stop functions.
