Information About
The 1791DS-IB8XOB8 is part of the Allen-Bradley Guard I/O family, engineered to support DeviceNet Safety architectures in industrial automation environments. Its safety inputs support single-channel sensing for emergency stops, safety mats, switches, and other protective devices, while the solid-state outputs handle safety outputs such as contactor control or enabling circuits. The module also includes four test outputs used for pulse-testing external devices to detect shorts, faults, or wiring anomalies. Typical applications include machinery requiring SIL 3/Category 4 safety compliance, such as robotic cells, presses, assembly lines, and safety interlock networks.
Key Features
- 8 Safety Inputs: Sinking configuration supporting devices requiring SIL 3 functional safety.
- 8 Solid-State Outputs: Current sourcing outputs rated for 0.5 A per channel.
- Four Test Outputs: Sourcing test pulse outputs for fault detection on input circuits.
- DeviceNet Safety Communication: Ensures reliable, certified safety data exchange.
- Integrated Diagnostics: Provides input, output, and test point status monitoring.
- Wide Operating Temperature Range: Functions from –40 to 70 °C for demanding environments.
- IP20 Open-Style Enclosure: Suitable for enclosure-mounted safety systems.
- High Electrical Durability: Supports 20.4–26.4 VDC I/O power and up to 110 mA communication consumption.
The 1791DS-IB8XOB8 delivers the reliability and precision required for SIL 3–rated safety I/O integration in DeviceNet safety networks.
