1734‑IB8S
Allen‑Bradley 1734‑IB8S POINT Guard I/O 8‑Channel Safety Sinking Digital Input Module
Product Overview
The 1734‑IB8S is a safety‑certified sinking digital input module for Rockwell Automation POINT Guard I/O distributed I/O system. It provides 8 safety‑rated sinking digital input channels for CIP Safety applications, working with 1734‑AENTR safety adapter and GuardLogix safety controllers over EtherNet/IP. This module supports single‑channel and dual‑channel redundant safety input modes. Four integrated pulse‑test sourcing outputs enable diagnostics for open‑wire, short‑circuit and cross‑wire faults on safety sensors. Hot‑swap capable on POINTBus backplane. Requires a separate 8‑position POINT I/O terminal base for field wiring. Available as new original, surplus and used‑refurbished aftermarket units。
Key Features
- 8‑channel safety‑certified sinking digital inputs (Type 3 per IEC 61131‑2)
- 4 built‑in current‑sourcing pulse‑test outputs for sensor fault diagnostics (open‑circuit, short‑circuit, cross‑fault detection)
- Safety certification: SIL 3 (IEC 61508), PL e, Cat 4 (ISO 13849) for functional safety‑related control
- Supports single‑channel and dual‑channel redundant safety input configuration, configurable discrepancy detection
- Hot‑swap capability for I/O modules without power‑down the POINT I/O assembly
- Multi‑color LED indicators: module health, safety lock status, individual channel status and test output status for fast on‑site troubleshooting
- Compatible with Studio 5000 Logix Designer safety programming environment
- Configurable safe‑state input behavior during communication loss
- Short‑circuit protection on test outputs; test outputs can also power external safety devices such as muting lamps
Electrical Specifications
- Nominal field supply voltage: 24 V DC; operating range 19.2‑28.8 V DC
- Input type: Sinking
- Input ON threshold: ≥11 V DC; minimum ON‑state input current: 3.3 mA per channel
- Input OFF threshold: ≤5 V DC; maximum OFF‑state leakage current: 1.3 mA per channel
- Maximum module reaction time: 16.2 ms
- Pulse‑test outputs: Sourcing, max 0.7 A per test channel; total 2.8 A @40 °C, derated at higher temperature
- POINTBus backplane current draw @5 V DC: 175 mA
- Max power dissipation: 1.4 W (4.8 BTU/hr)
- Isolation: basic insulation between field circuit and POINTBus backplane; no channel‑to‑channel isolation

- Storage temperature: ‑40 °C … +85 °C
- Relative humidity: 5‑95 % non‑condensing
- Protection rating: IP20, cabinet / DIN‑rail installation only
- Mounting: 35 mm standard DIN‑rail via POINT I/O terminal base
- Dimensions (module only): 77 mm × 25 mm × 55 mm
- Weight: approx. 90 g (0.19 lbs)
- Certifications: cULus, CE, UKCA, TÜV‑approved for functional safety
Ordering Information
- Part Number: 1734‑IB8S
- UPC: 612598350612
- Series: POINT Guard I/O Bulletin 1734, typical hardware Series B
- Lifecycle Status: Active, original production available
- Original factory warranty: 1‑year Rockwell Automation warranty (not valid for used / surplus stock)
