Information About 1734-OBV2S

The Allen-Bradley 1734-OBV2S is a compact POINT Guard I/O module designed for implementing safety-rated output control within distributed safety systems. Offering four solid-state bipolar outputs arranged in two safety pairs, it supports dual-channel operation for SIL-rated and Category-compliant safety circuits. Operating at 24VDC, the module integrates seamlessly into POINT I/O and Guard I/O architectures, making it ideal for applications requiring safe stopping, actuator control, and emergency shutdown functions. Its IP20 in-cabinet design and DIN-rail mounting simplify installation in modular automation systems while maintaining compliance with global safety certifications.

Key Features:

  • Four Bipolar Solid-State Safety Outputs: provides reliable switching performance for actuators, relays, and safety devices, with two independent safety pairs for redundant or dual-channel operation.
  • Dual-Channel Safety Functionality: supports SIL-rated and PLd/PLe safety architectures by enabling cross-monitoring between paired outputs to detect faults and ensure safe machine response.
  • Integrated POINT Guard I/O Architecture: works seamlessly within POINT and Guard I/O platforms, allowing flexible distributed safety configurations across EtherNet/IP safety networks.
  • 24VDC Industrial Operation: designed for standard 24VDC control systems, delivering consistent output behavior in safety-critical automation environments.
  • Solid-State Switching Reliability: offers long service life with wear-free electronic outputs, reduced maintenance, and improved reliability over mechanical safety relays.
  • Compact IP20 Cabinet Design: optimized for control panel installation, conserving space while maintaining easy access to wiring and module diagnostics.
  • Global Safety Certification: compliant with CE, UL, C-UL, KC, and RCM requirements, ensuring suitability for international machine safety applications.

The 1734-OBV2S delivers the reliability and precision required for safe actuator control, dual-channel machine safeguarding, and distributed safety architectures in modern automation systems.

Frequently Asked Questions about 1734-OBV2S
Question: What is the 1734-OBV2S?
Date Update:20/06/2025
Answer:

The 1734-OBV2S is a safety output module used in Point I/O systems to control actuators such as relays or contactors in safety-related applications. It offers 2 pairs of bipolar outputs that can operate in sourcing or sinking mode. This configuration allows the module to support redundant safety outputs. It is commonly used in systems requiring SIL CL3 or PLe Cat. 3/4 compliance. It integrates seamlessly with GuardLogix or SmartGuard controllers.

Question: What is the current rating of 1734-OBV2S?
Date Update:20/06/2025
Answer:

The 1734-OBV2S safety module has a current rating that depends on the operating temperature. Each bipolar output pair can deliver up to 1.25 Amps at 40°C and 0.5 Amp at 55°C. This thermal derating ensures safe and reliable performance across varying temperature conditions. Always consider this when planning load connections, as exceeding the limit can cause thermal shutdown or damage.

Question: How do I reset my 1734-OBV2S?
Date Update:20/06/2025
Answer:

To reset your Allen-Bradley 1734-OBV2S safety output module, follow this step-by-step process:

  • Step 1: Diagnose the fault condition
    Use your safety controller (e.g., GuardLogix or SmartGuard) to check for any fault messages or diagnostics indicating why the module is in a faulted state.
  • Step 2: Clear the safety faults
    In your safety application logic (Studio 5000), use the Reset Safety instruction or clear the fault bit associated with the module.
  • Step 3: Verify wiring and field devices
    Inspect all wiring, loads, and feedback circuits connected to the output channels. Faults like short circuits or load mismatches must be corrected before resetting.
  • Step 4: Power cycle if needed
    If the fault persists or if required by your controller logic, perform a power cycle by turning off the field power and reapplying it after a few seconds.
  • Step 5: Confirm module status
    Check the module status LEDs to ensure that it has returned to normal operation. Green indicators typically confirm a healthy state.

This procedure ensures the 1734-OBV2S returns to a safe, operable state while maintaining compliance with your safety system logic.

Question: What controllers are compatible with 1734-OBV2S?
Date Update:20/06/2025
Answer:

The 1734-OBV2S is compatible with the following Rockwell Automation safety controllers:

  • SmartGuard 600
  • Compact GuardLogix
  • Standard GuardLogix
  • Other safety-rated Logix controllers with Point I/O adapters

These controllers allow full integration of safety and standard I/O in a single platform.

Question: Is the 1734-OBV2S still in production?
Date Update:20/06/2025
Answer:

Yes, the 1734-OBV2S is actively manufactured and supported by Rockwell Automation.
