Overview of Allen-Bradley 1734-IB8S POINT I/O Guard I/O Safety Module

The Allen-Bradley 1734-IB8S is a safety-certified POINT I/O Guard I/O module designed for safety applications with SIL (Safety Integrity Level) ratings. It features eight current sinking safety input channels and four current sourcing pulse test outputs. This module supports dual-channel mode for evaluating consistency between two input signals for higher safety categories and single-channel mode for lower safety needs, making it versatile for various safety functions.

Key Features of 1734-IB8S

  • Eight (8) current sinking safety input channels for reliable safety device monitoring.
  • Four (4) current sourcing pulse test outputs to verify input wiring integrity.
  • Dual-channel mode enables applications that meet Safety Category 3 and 4 requirements.
  • Single-channel mode allows usage for Safety Category 2 applications.
  • Configurable discrepancy time to determine allowable time difference before declaring a fault.
  • External wiring short check to enhance safety diagnostics when used with test outputs.
  • Individually adjustable ON and OFF signal delays to reduce false positives and negatives from signal fluctuations.
  • Operates at nominal 24 V DC supply voltage within 19.2 to 28.8 V DC range.
  • Power bus max current (no load): 25 mA.
  • Continuous isolation voltage: 50 V.
  • Maximum thermal dissipation: 11.62 BTU/hr (3.4 W).
  • Dimensions: 77 x 25 x 55 mm (3.03 x 0.98 x 2.17 inches).
  • Open-style enclosure, mountable horizontally or vertically.
  • Compatible with SmartGuard, GuardLogix, and Compact GuardLogix controllers.
  • Communication supported over Ethernet/IP and DeviceNet networks via 1734-AENT, 1734-AENTR, or 1734-PDN adapters.
