Engineering Advantages

The 1734-4IOL addresses the critical requirements of Industry 4.0 and complex machine diagnostics:

Real-Time Device Health Monitoring: This module extracts comprehensive diagnostic data from IO-Link enabled sensors. It detects conditions like lens soiling or internal temperature spikes before a failure occurs, shifting maintenance from reactive to predictive.

Automatic Device Configuration (ADC): The 1734-4IOL stores the configuration parameters of connected sensors. When a technician replaces a damaged sensor, the master module automatically downloads the settings to the new device, eliminating manual setup errors and reducing downtime.

Advanced Wiring Simplification: The module utilizes standard 3-wire unshielded cables for intelligent communication. This replaces expensive specialized cables and reduces the overall complexity and cost of the control cabinet wiring.

Granular Process Insights: Beyond simple On/Off signals, the 1734-4IOL transmits precise process values (such as exact distance measurements or pressure levels) as digital data, preventing signal degradation caused by electromagnetic interference (EMI) in analog circuits.

FAQs

Can I use standard digital sensors with the 1734-4IOL?

Yes. Each channel on the 1734-4IOL supports standard I/O (SIO) mode. You can connect traditional 24V DC digital sensors to any channel, providing a flexible migration path from standard I/O to smart IO-Link technology.

Which terminal base is best for the 1734-4IOL?

We recommend the 1734-TB or 1734-TBS base. Ensure you utilize the 8-terminal configuration to provide adequate power distribution for both the module electronics and the connected field devices.

Does this module support "Removal and Insertion Under Power" (RIUP)?

Yes. Like other POINT I/O modules, the 1734-4IOL allows for replacement while the rest of the system remains operational. This feature is critical for continuous process industries where shutting down the entire I/O rack is not an option.

How does the 1734-4IOL handle power to the sensors?

The module draws 24V DC from the POINT I/O backplane power bus. It distributes this power to the connected IO-Link devices through the L+ and L- pins, supporting up to the maximum rated current per port as specified in the technical manual.
