Allen-Bradley 1734-IB8S/B POINT I/O Safety Input Module Overview
The Allen-Bradley 1734-IB8S/B is a high-performance safety input module engineered for demanding industrial environments where personnel protection and equipment safety are paramount. This 8-channel sinking input module integrates seamlessly into POINT I/O distributed control architectures, delivering SIL 3 and PLe certified safety performance for emergency stop circuits, light curtains, safety interlocks, and guard monitoring applications.
Technical Specifications
- Model Number: 1734-IB8S/B
- Input Channels: 8 safety-rated sinking inputs
- Safety Rating: SIL 3 (IEC 61508), PLe Category 4 (ISO 13849-1)
- Input Voltage Range: 24V DC nominal (19.2-30V DC operating range)
- Input Current: 7 mA typical per channel
- Response Time: ≤10 ms for safety-critical signals
- Diagnostic Coverage: >99% with comprehensive fault detection
- Operating Temperature: 0°C to 60°C (32°F to 140°F)
- Mounting: DIN rail via 1734-TB or 1734-TBS terminal base
- Certifications: UL, cUL, CE, TÜV, ATEX Zone 2
- Weight: 62.4 grams (0.138 lbs)
Key Applications & Use Cases
Deploy the 1734-IB8S/B across diverse safety-critical scenarios:
- Emergency Stop Systems: Monitor E-stop buttons and safety relays with dual-channel redundancy for fail-safe machine shutdown
- Perimeter Guarding: Interface with safety light curtains, laser scanners, and area sensors to protect operator zones
- Interlock Monitoring: Supervise gate switches, door locks, and access panels to prevent hazardous machine access
- Robotic Workcells: Integrate with collaborative robot safety systems and presence-sensing mats
- Process Safety: Connect to pressure switches, temperature monitors, and level sensors for safe process control
Engineering Solutions & System Integration
The 1734-IB8S/B simplifies safety system design through native compatibility with Allen-Bradley GuardLogix and Compact GuardLogix safety controllers. Utilize CIP Safety protocol over EtherNet/IP for deterministic, black-channel communication that eliminates dedicated safety wiring. The module's dual-processor architecture continuously validates input integrity, detecting short circuits, wire breaks, and cross-circuit faults within milliseconds.
Pair with 1734-TOP terminal bases for quick installation, or select 1734-TBS spring-clamp bases for vibration-resistant connections. Combine with ControlLogix L83EP controllers for integrated safety and standard control in a unified platform.
Frequently Asked Questions
Q: What is the difference between sinking and sourcing safety inputs?
A: The 1734-IB8S/B uses sinking inputs, meaning the module provides the common (0V) connection while safety devices switch the positive 24V DC supply. This configuration is ideal for NPN-type sensors and European-standard safety devices.
Q: Can I mix safety and standard I/O on the same POINT I/O rack?
A: Yes, POINT I/O architecture allows mixing of safety and standard modules on a single adapter, though safety modules require connection to a GuardLogix safety controller for certification compliance.
Q: What diagnostic features are included?
A: The module provides channel-level diagnostics including input state monitoring, discrepancy detection between redundant channels, power supply status, and communication health indicators accessible via Studio 5000 software.
Q: Is this module suitable for SIL 3 applications?
A: Absolutely. The 1734-IB8S/B is TÜV certified for SIL 3 (IEC 61508) and PLe Category 4 (ISO 13849-1) when configured according to Rockwell Automation safety reference manuals.
Warranty & Support
Every 1734-IB8S/B module includes a comprehensive 12-month warranty covering manufacturing defects and material failures. Our technical support team provides configuration assistance, troubleshooting guidance, and integration consulting to ensure successful deployment in your safety systems.
