Product Overview
The Allen-Bradley 1734-IB8S is a POINT Guard I/O safety digital input module manufactured by Rockwell Automation. It provides eight 24V DC current-sinking safety inputs and four current-sourcing pulse test outputs for supported industrial safety-control applications. The module operates with a nominal 24V DC field power supply and a manufacturer-specified supply range of 19.2–28.8V DC. Its safety inputs support an ON-state voltage range of 11–30V DC at 40°C, derated to 11–28.8V DC at 55°C. The 1734-IB8S provides a manufacturer-specified safety input reaction time of less than 16.2 milliseconds. Configurable input filters from 0 to 126 milliseconds, in 6ms increments, allow the OFF-to-ON and ON-to-OFF filter settings to be adjusted according to the safety application. Four integrated pulse test outputs provide diagnostic support for appropriate safety input circuits. Each test output supports up to 0.7A at 40°C, subject to the manufacturer's total module current and temperature-derating limits. The module is part of the POINT Guard I/O architecture and can be integrated into supported safety-control systems. When the complete system is properly designed, configured and validated, the architecture can support safety applications up to SIL CL 3 / PL e, Category 4. These ratings are not a substitute for application-specific safety validation. Rockwell Automation currently lists the exact catalog number as Active. The supplied actual packaging photograph identifies 1734-IB8S, Series B, serial marking 335758, packaging date 2026/06/03 and PRODUCT OF SINGAPORE. The physical module nameplate, firmware version, included terminal base and functional performance have not been independently verified. Please confirm the controller platform, safety network, terminal base, electrical configuration and safety application requirements before ordering.
