Allen-Bradley 1734-IB8S | 8-Channel Safety Digital Input Module for POINT I/O with SIL 3 / PLe Certification
Overview
The Allen-Bradley 1734-IB8S is an 8-channel safety-rated digital input module designed for POINT I/O systems. Operating at 24V DC sinking input, this module supports CIP Safety over EtherNet/IP, making it ideal for distributed and safety-critical automation systems. It is TÜV certified for SIL 3 and PLe functional safety standards.
Key Features
-
8 Digital Inputs – 24V DC sinking (PNP) configuration
-
Safety-Rated – Complies with SIL 3 (IEC 61508) and PLe (ISO 13849-1)
-
CIP Safety over EtherNet/IP – Integrates seamlessly with GuardLogix controllers
-
Diagnostics and Status LEDs – Channel-level and module-level feedback
-
DIN Rail Mounting – Compact POINT I/O footprint
-
Hot-Swappable – Replaceable without system shutdown
