Allen-Bradley 1734-OB8S 8-Channel Safety Sourcing Output – POINT I/O Safety Module
Imagine a high-speed automotive assembly line or a chemical processing plant where a safety output module fails without warning. Emergency stop circuits lose their commanded response, light curtains cannot de-energize hazardous drives, and the entire safety-rated control loop is compromised — forcing an unplanned shutdown, regulatory non-compliance, and potential risk to personnel. In safety-critical industrial environments, every output channel must be certified, traceable, and unfailingly reliable. The Allen-Bradley 1734-OB8S is precisely the component that prevents this scenario.
The 1734-OB8S is Allen-Bradley’s 8-channel safety sourcing digital output module within the POINT I/O platform — one of the most widely deployed modular I/O architectures in global industrial automation. Designed to meet IEC 61508 SIL 2 and EN ISO 13849-1 PLd safety standards, this module integrates seamlessly into Rockwell Automation GuardLogix and CompactGuardLogix safety controller ecosystems. Its compact DIN-rail form factor and hot-swap capability make it a preferred choice for OEMs and system integrators across automotive, food & beverage, oil & gas, and discrete manufacturing sectors worldwide.

Frequently Asked Questions
Q: What is the safety rating of the Allen-Bradley 1734-OB8S?
A: The 1734-OB8S is rated for SIL 2 per IEC 61508 and Performance Level d (PLd) per EN ISO 13849-1, making it suitable for safety-critical applications up to Category 3 machinery.
Q: Can the 1734-OB8S be used with non-safety (standard) POINT I/O adapters?
A: No. Safety I/O modules like the 1734-OB8S require a safety-rated adapter and a GuardLogix or CompactGuardLogix safety controller to function in safety mode. They cannot be used with standard ControlLogix or CompactLogix controllers for safety functions.
Q: Is the 1734-OB8S hot-swappable?
A: Yes. The POINT I/O platform supports hot-swap of I/O modules, allowing replacement without shutting down the entire I/O rack, which minimizes production downtime during maintenance.
Q: What communication protocols does the 1734-OB8S support?
A: The module itself communicates via the POINT I/O backplane. The network protocol (EtherNet/IP, DeviceNet, ControlNet, PROFIBUS) is determined by the adapter module used in the same POINT I/O station.
Q: How do I verify the authenticity of a 1734-OB8S purchased from Konmask.com?
A: We provide traceability documentation and certificate of conformity upon request. You can also verify the module’s date code and catalog number against Rockwell Automation’s official product records.
Q: What is the lead time for the Allen-Bradley 1734-OB8S?
A: Lead time varies based on current stock and your delivery location. Please submit an inquiry and our team will provide confirmed availability and estimated delivery within 1 business day.
