Information About 1734-4IOL

The 1734-4IOL is part of the Allen-Bradley POINT I/O 1734 series, developed for modular and flexible distributed I/O. This module supports four Class A IO-Link master channels, enabling connection of IO-Link sensors, actuators, and field devices. Each channel can also operate as a standard digital input/output, offering application flexibility. IO-Link communication allows access to extended device data, diagnostics, and parameterization, improving system visibility and reducing downtime. The module integrates with CompactLogix and ControlLogix controllers via EtherNet/IP adapters and is configured in Studio 5000 Logix Designer. DIN rail–mounted and compact, the 1734-4IOL enables scalable installation in distributed architectures while supporting Industry 4.0 and smart manufacturing initiatives.

Key Features:

  • Design: POINT I/O module with 4 IO-Link master channels.
  • Functionality: Supports IO-Link devices for advanced sensing and actuation.
  • Flexibility: Each channel can also act as a standard digital input/output.
  • Diagnostics: Provides extended device diagnostics and parameter data via IO-Link.
  • Integration: Works with CompactLogix and ControlLogix controllers over EtherNet/IP.
  • Configuration: Set up and monitored through Studio 5000 Logix Designer.
  • Installation: Compact DIN rail–mounted design for distributed I/O.
  • Application Range: Suitable for packaging, machine control, and Industry 4.0 smart device integration.

The 1734-4IOL delivers the intelligence, flexibility, and connectivity required for integrating smart sensors and actuators into modern industrial automation systems.

Frequently Asked Questions about 1734-4IOL
Question: How does the 1734-4IOL module connect to a network?
Date Update:30/05/2025
Answer:

The module communicates over an Ethernet-based network through a POINT I/O adapter, integrating with control systems like CompactLogix or ControlLogix. It is mounted on a DIN rail and connects via the POINT I/O backplane. The IO-Link protocol ensures seamless communication with smart sensors and actuators. This setup makes it ideal for distributed control and flexible system design.

Question: What is the maximum cable length for IO-Link devices connected to the 1734-4IOL?
Date Update:30/05/2025
Answer:

The module supports device cable lengths up to 20 meters. This allows for installation flexibility in distributed I/O architectures. Longer cable runs can accommodate various machine layouts and remote device locations. However, proper cable shielding is recommended to prevent noise interference.

Question: What are the environmental ratings for the 1734-4IOL?
Date Update:30/05/2025
Answer:

The module is rated for operation in temperatures up to 131 degrees Fahrenheit (55 degrees Celsius). It is designed for in-cabinet installation to protect it from dust and moisture. Its thermal dissipation rating is 5.12 BTU/hr at 28.8V DC, and power dissipation is 1.5W at the same voltage. These specifications help ensure safe and reliable performance in industrial environments.

Question: How should the wiring be connected for IO-Link sensors with the 1734-4IOL module?
Date Update:30/05/2025
Answer:

The correct wiring for an M12 connector should be: brown wire to power (+24V), blue wire to common (0V), and black wire to the IO-Link signal input. Miswiring is a common mistake that prevents communication. Always refer to the sensor’s datasheet and the 1734-4IOL manual to confirm wiring order. Double-check that the wiring order on the terminal block matches the expected configuration.

Question: What should I check if I still can’t establish communication after verifying the wiring?
Date Update:30/05/2025
Answer:

Check the following:

  • Confirm the module’s channel mode is set to IO-Link (not standard digital input/output).
  • Verify the correct IODD file is installed in Studio 5000 for the sensor.
  • Double-check the wiring order (brown to power, blue to common, black to signal) and ensure it matches on both ends.
  • Make sure the sensor is correctly set to IO-Link mode and not to discrete output mode.
  • Confirm that there’s no cable damage or loose connections that could cause intermittent failures.
