Allen-Bradley 1734-OB8S 8-Channel Safety Digital Output Module

Allen-Bradley 1734-OB8S POINT Guard I/O 8-channel safety sourcing output module provides eight 24V DC safety outputs for a POINT I/O rack in GuardLogix safety networks. Each channel is monitored with an on‑board status indicator, enabling quick fault diagnosis and verification of output states. The module supports pulse-test diagnostics and readback to verify correct operation of safety circuits, a key feature for commissioning and ongoing safety verification. It can operate in single-channel mode (certified for functional safety in that configuration) or dual-channel mode, offering redundancy for safety-critical applications. Designed to drive safety-rated actuators, relays, or interlocks, the OB8S integrates with POINT I/O bases and safety controllers to deliver coordinated safety logic and real-time feedback across the distributed I/O network. Typical applications include machine guarding, emergency-stop circuits, and safety interlocks within automated production lines, where a compact, field‑bus I/O solution is required to meet safety standards while preserving rack space and system simplicity. As part of Rockwell Automation’s POINT I/O safety family, the OB8S supports reliable safety output control within GuardLogix‑based control architectures, delivering governed outputs aligned with functional-safety requirements and diagnostic data to support maintenance and fault management.
