Information About 1734-OB4

The 1734-OB4 is part of the POINT I/O family, offering four discrete 24 VDC sourcing outputs for modular, distributed control architectures. It supports an operating voltage range of 10–28.8 VDC with up to 2 A per point, allowing it to drive solenoids, indicators, and low-power actuators in safety-related and standard control circuits. The module uses screw-type terminal connections, integrates easily onto a POINT I/O DIN-rail base, and communicates through a backplane interface to support flexible expansion. With global certifications such as CE, UL, C-TICK, KC, GOST, Marine, and an operating temperature range from –20 °C to 55 °C, it is suitable for industrial environments requiring compact, open-style output modules.

Key Features:

  • Four 24 VDC Sourcing Outputs: Provides reliable digital control for actuators, lights, and general automation devices in POINT I/O systems.
  • 10–28.8 VDC Rated Operating Range: Ensures stable performance across a wide variety of 24 VDC control power setups.
  • Up to 2 A Output Capability: Supports higher-current loads on each channel while maintaining module reliability.
  • Screw Terminal Connections: Allows secure and vibration-resistant field wiring for industrial applications.
  • DIN-Rail Mounted POINT I/O Format: Enables compact, scalable installation within distributed or machine-mounted control systems.
  • Open-Style Construction: Designed for cabinet installation while maintaining excellent ventilation and easy access.
  • Wide –20 °C to 55 °C Temperature Range: Suitable for use in both cold and warm control environments.
  • Global Industrial Certifications: Meets CE, UL, C-TICK, KC, GOST, CUL, and Marine standards for regulated installations.

The 1734-OB4 delivers the reliability and precision required for efficient 24 VDC digital output control in distributed POINT I/O automation systems.

Frequently Asked Questions about 1734-OB4
Question: What is the 1734-OB4?
Date Update:12/06/2025
Answer:

The 1734-OB4 is a digital output module from the POINT I/O family of I/O modules by Allen-Bradley. It has 4 output channels that can be used to control external devices, such as relays, solenoids, or actuators, in an industrial automation system. The module is designed for easy integration into ControlLogix or CompactLogix systems and communicates via Ethernet/IP or other backplane protocols.

Question: Where can I find the manual for the 1734-OB4?
Date Update:12/06/2025
Answer:

The manual for the 1734-OB4 can be found on the Rockwell Automation website. To access the manual:

  • Visit the Rockwell Automation website.
  • Navigate to the Support or Downloads section.
  • Search for 1734-OB4 in the product documentation section.
  • Download the user manual, which includes detailed information on wiring, configuration, installation, and troubleshooting.

Alternatively, you can check the documentation within RSLogix 5000 or Studio 5000 if you're using this software for programming your PLC.

Question: What is the wiring configuration for the 1734-OB4?
Date Update:12/06/2025
Answer:

The 1734-OB4 module provides 4 digital output channels, which can be used to control devices like relays or actuators. The wiring configuration depends on the type of load you're controlling (e.g., standard relay, solenoid, or light). Here’s how to wire the module:

1. Power Supply:

  • The 1734-OB4 module is powered by the POINT I/O backplane. It is important that the backplane is powered correctly to ensure the module operates as expected.

2. Output Connections:

  • For Standard DC Loads (e.g., solenoids, relays):
    Connect the positive terminal of the load to the output terminal (for example, O0, O1, O2, O3).
    Connect the negative terminal of the load to the common terminal (e.g., C0).
  • For AC Loads: The module is DC-only, meaning it cannot be used for directly controlling AC devices. An external relay or solid-state relay (SSR) should be used to interface AC loads with the 1734-OB4.

3. Common Terminal:

  • The 1734-OB4 module has a common terminal (labeled C0), which is shared by all 4 outputs. When wiring, ensure the common terminal is properly connected to the ground or return path of your load.

Always refer to the wiring diagram provided in the user manual for the exact terminal locations and configuration for your application.

Question: What are the diagnostic features of the 1734-OB4?
Date Update:12/06/2025
Answer:

The 1734-OB4 module provides several diagnostic features that can be accessed through the PLC or through the module’s LED indicators. These diagnostics help to monitor the health of the module and ensure proper operation:

  1. Status LED: The status LED indicates the operational status of the module. If the LED is solid green, the module is functioning normally. A flashing red LED or a solid red LED typically indicates an issue with the module.
  2. Output LEDs: Each output channel (O0, O1, O2, O3) has an associated LED that indicates whether the output is energized or de-energized. If an output is energized, the corresponding LED will be illuminated.
Question: What is the voltage range for the outputs on the 1734-OB4?
Date Update:12/06/2025
Answer:

The 1734-OB4 module provides 24V DC output signals. The output points are typically designed for on/off control (digital control) and can source or sink current to connected devices. The typical output voltage range is 20.4V to 26.4V DC.
