Information About 1791DS-IB12
The 1791DS-IB12 belongs to the Guard I/O 1791DS family and is engineered for DeviceNet-based safety systems. Its design features 12 current-sinking inputs and built-in test outputs, enabling compatibility with standard and safety devices across industrial environments. The module supports direct DIN rail mounting with an integrated clip and requires adequate ventilation clearance for proper thermal performance. It is typically used in applications involving safety relays, emergency stop circuits, and safety interlocks requiring networked diagnostic capability.
Key Features:
- 12 safety-rated inputs: Single-channel input design for guard switches and safety devices.
- DeviceNet safety communication: Integrates into Guard I/O systems using CIP Safety over DeviceNet.
- Wide DC operating range: Accepts 20.4–26.4 V DC I/O power for flexible installation.
- Test pulse outputs: Supports verification of input wiring integrity.
- DIN rail mountable: Equipped with a rail attachment hook for simple installation.
- Compact module footprint: Suitable for distributed safety I/O deployment.
- Hazardous location approval: Rated for North American hazardous environments.
- Clear on/off thresholds: 11 V minimum on-state and 5 V maximum off-state voltage limits.
The 1791DS-IB12 delivers the reliability and precision required for distributed safety input monitoring in DeviceNet-based control systems.
