Engineering Advantages
The 1746-FIO4I provides technical solutions for demanding process control environments:
-
High-Speed Data Conversion: The module utilizes a successive approximation method to achieve a 512-microsecond update time. This rapid processing ensures real-time accuracy for high-speed motion or pressure control applications where every millisecond counts.
-
Superior Signal Integrity: A 1.5 µs track-and-hold time captures transient analog values before conversion. This eliminates data skew and ensures the CPU receives an accurate representation of the field signal, even in environments with fluctuating process variables.
-
Optimized Rack Density: By combining both input and output functions into a single-slot width, the 1746-FIO4I frees up valuable chassis slots for other communication or digital modules. This reduces the overall hardware footprint of your SLC 500 system.
-
Robust Noise Immunity: The 7 kHz bandwidth specifically targets and filters industrial electrical noise. This ensures that the 12-bit input and 14-bit output signals remain stable and jitter-free, even when field cables run near high-voltage motor lines.
FAQs
-
Can I use both voltage and current inputs simultaneously?
Yes. The 1746-FIO4I allows you to configure its two inputs independently. You can monitor a 0-10 VDC signal on one channel while receiving a 0-20 mA signal on the other, providing maximum flexibility for different field sensors.
-
Is this module compatible with SLC 5/01 and 5/02 processors?
The 1746-FIO4I works with SLC 500 Fixed, Modular, and Remote I/O systems. However, check your specific processor's instruction set to ensure it supports the advanced analog data handling required for this combination module.
-
What is the condition of this 1746-FIO4I unit?
We offer this product in 100% Brand New original condition. It ships in the authentic Allen Bradley factory box with the original UPC (662468523400) and factory documentation included.
-
Does this module require an external power supply?
The module draws 150 mA from the 24V DC backplane. Ensure your SLC power supply (such as a 1746-P1 or P2) has sufficient remaining capacity to support this load alongside your other installed modules.

Tech & Buying Guide
Redundant Automation Systems: Ensuring Continuous Uptime in Critical Control Infrastructure
System reliability directly determines operational profitability across high stakes process industries. Modern industrial automation platforms must eliminate single points of failure to prevent catastrophic shutdowns. Deploying fault tolerant architecture safeguards complex facilities against unexpected hardware glitches, network disruptions, and maintenance outages.
Understanding Types of Noise in Electronic Circuits and Control Systems
Signal integrity directly determines measurement accuracy and loop stability across industrial automation environments. Electronic noise introduces unwanted stochastic interference into analog loops, sensor feedback lines, and digital fieldbus networks. Understanding how intrinsic electronic noise and external electromagnetic interference manifest allows control engineers to optimize signal conditioning and shield sensitive instrumentation effectively.
Why 24V DC Power Supplies Standardize Modern Industrial Automation
Industrial control cabinets worldwide rely on 24V DC as the universal power standard for field instrumentation, sensors, and controllers. Walk into any manufacturing plant, and you will find PLCs, human-machine interfaces (HMIs), and smart actuators running on extra-low voltage DC. Standardizing on 24V DC enhances operational safety, lowers cabinet footprint, and maintains steady control performance across factory networks.
