Allen-Bradley 1734-IB8S Digital Safety Input Module

The Allen-Bradley 1734-IB8S is an 8-channel, 24V DC digital safety input module for POINT Guard I/O systems. It monitors safety input signals—such as emergency stops, safety switches, light curtains, and interlock devices—and provides safety-rated signal processing to support safe machine operation in manufacturing and process environments. Designed for DIN rail mounting in POINT I/O racks, it integrates with Allen-Bradley POINT I/O systems to expand or retrofit safety capabilities on automation installations. The module is SIL/PL compliant, reflecting its safety-rated status, and is commonly used in safety control configurations for machine protection. Common replacements include Allen-Bradley 1734-IB8 Digital Input Module, 1734-IB4S Safety Input Module, and 1734-OB8S Safety Output Module.
