Allen-Bradley 1734-IB8S Safety Sinking Input Module

The Allen-Bradley 1734-IB8S is an 8-point safety sinking digital input module for POINT I/O Guard I/O systems that monitors safety devices within Logix-based control architectures. It accepts 24V DC safety field devices such as emergency stops and safety interlock switches and reports status signals to GuardLogix or Compact GuardLogix controllers as part of distributed safety I/O. This DIN-rail mounted module provides eight sinking inputs (for sourcing field devices) and communicates through a POINT I/O safety adapter to integrate with the POINT I/O Guard I/O platform. Key specifications include 24V DC input, 8 safety inputs, an operating range of 0 to 55°C, and a safety category of SIL 3 / PL e (system dependent). Common replacements include 1734-IB8SK and 1734-OB8S, and it is commonly used in machine safety panels, robotic cells, packaging equipment, and automated production lines that require monitored safety inputs in Logix-based safety architectures.
