Information About 1791ES-IB8XOBV4
The 1791ES-IB8XOBV4 is a CompactBlock Guard I/O safety module that operates as part of Allen-Bradley’s EtherNet/IP functional safety architecture. It includes a ruggedized block-style housing and is fully compatible with GuardLogix and other EtherNet/IP safety controllers. The module supports Type 3 IEC 61131-2 input circuits and provides onboard diagnostics for identifying wiring faults, cross-circuits, and output feedback issues. Its integrated Ethernet interface allows configuration through rotary switches, BOOTP/DHCP services, or stored non-volatile settings, making it suitable for distributed machine safety systems.
Key Features:
- Eight Safety Inputs: Supports Type 3 current-sinking safety inputs with 11 VDC minimum ON voltage and 3.3 mA minimum ON current.
- Four Bipolar Outputs: Provides sourcing/sinking paired outputs rated up to 2 A per point for controlling safety devices.
- Integrated EtherNet/IP Interface: Includes a single RJ45 port for safety network communications and parameter configuration.
- Advanced Diagnostics: Monitors input status, output status, readback conditions, and wiring faults for improved safety visibility.
- Pulse Test Outputs: Supplies diagnostic pulse signals for detecting shorts and validating field wiring integrity.
- Electronic Protection: Includes short-circuit detection and electronic safeguarding for reliable output operation.
- Wide DC Operating Range: Functions from 19.2 to 28.8 VDC to support industrial low-voltage safety systems.
- CompactBlock Form Factor: Designed for distributed mounting close to machinery to reduce wiring lengths.
The 1791ES-IB8XOBV4 delivers the reliability and precision required for safe and efficient control of machine-level safety circuits.
