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

The Allen-Bradley 1734-OB8S POINT Guard I/O Safety Digital Output Module provides eight safety-rated outputs for distributed safety control within POINT Guard I/O systems, ideal for safety circuits, emergency-stop setups, and machine-safety applications. Each channel is a current-sourcing (solid-state) output at 24V DC nominal with a maximum of 1 A per channel and up to 8 A total per module, featuring a response time of ≤ 6.2 ms and electronic short-circuit protection; the module offers 50 V continuous isolation between field and system. It draws 190 mA from the POINTBus, dissipates approximately 3–4.5 W, and measures about 77 × 25 × 55 mm, with status LEDs for power, lock, and channel status, operating from a 24 V DC supply (19.2–28.8 V) and a temperature range of -20 to 55°C. The 1734-OB8S integrates with GuardLogix and POINT Guard I/O systems and has common replacements including 1734-OB8SK and 1734-OB8, reflecting its active lifecycle in Rockwell Automation's safety-enabled I/O portfolio.
