As a trusted supplier in industrial automation with over a decade of experience since 2011, Rossonix Co., Limited is proud to offer genuine Allen-Bradley components to a global clientele. We specialize in providing reliable, high-performance modules like the Allen-Bradley 1746-IA16, a cornerstone for robust control system architectures. This SLC 500 Digital AC Input Module is engineered for durability and precision, serving as a critical interface between your field devices and the central processor. Our commitment, backed by ISO9001 certified quality management, ensures you receive components that meet the rigorous demands of modern industrial applications, supported by our established logistics network from key ports like Shenzhen and Hong Kong.
The Allen-Bradley 1746-IA16 module is designed to integrate seamlessly into the versatile SLC 500 programmable controller platform. It provides sixteen isolated input channels for monitoring AC voltage signals from devices such as switches, sensors, and pushbuttons. This module converts these high-level AC signals into logic-level signals understandable by the SLC 500 processor, enabling precise control and monitoring functions within your automation system.
Key Technical Specifications & Features:
- High-Density Input Design: Accommodates up to 16 discrete AC input points on a single module, optimizing rack space and reducing the need for multiple modules in larger systems.
- Wide Operating Voltage Range: Accepts input signals from 85 to 132V AC, offering compatibility with standard industrial control voltages and providing reliable operation even with minor line fluctuations.
- Advanced Diagnostic Capabilities: Each of the 16 input channels is equipped with an individual LED status indicator. This allows for immediate visual confirmation of the input state (ON/OFF), drastically simplifying troubleshooting and maintenance procedures on the plant floor.
- Electrical Isolation: Features field-side to logic-side isolation rated at 1500V AC, protecting the sensitive backplane and processor from potential voltage transients, noise, or faults originating in the field wiring.
- Low Power Consumption: Draws only 0.25A from the SLC 500 backplane's 5V DC supply, ensuring efficient power usage and allowing for more modules to be installed within the power budget of the chassis.
- Robust Industrial Construction: Built to withstand the electrical noise, vibration, and temperature variations commonly found in industrial environments, ensuring long-term reliability.
The primary benefits for your operation are substantial:
- Enhanced System Reliability: The proven design and electrical isolation minimize downtime caused by input module failures or field-side electrical issues.
- Simplified Maintenance & Diagnostics: Per-point LED indicators enable technicians to quickly identify faulty field devices or wiring problems, reducing mean time to repair (MTTR).
- Cost-Effective Expansion: The 16-point density provides a economical solution for adding input capacity to existing SLC 500 systems or designing new, space-efficient control panels.
- Seamless Integration: As a native Allen-Bradley component, it guarantees full compatibility with the SLC 500 hardware and software ecosystem, including RSLogix 500 programming software, ensuring predictable performance and easy configuration.

Frequently Asked Questions (FAQ)
Q1: Is this module compatible with all SLC 500 processors?
A: Yes, the 1746-IA16 is fully compatible with the entire family of SLC 500 processors (e.g., SLC 5/01, 5/02, 5/03, 5/04, 5/05) and can be used in any SLC 500 modular or fixed I/O chassis.
Q2: What is the difference between a sinking and sourcing input module, and which is this?
A: This module (1746-IA16) is configured as a sinking input. In a sinking input module, the common terminal is connected to the DC- or AC neutral, and current flows into the input terminal from the field device. It's crucial to match your field device (e.g., a proximity sensor) to the correct input type for proper circuit operation.
Q3: Can I mix AC and DC input modules in the same SLC 500 chassis?
A: Absolutely. The SLC 500 backplane provides isolated power rails, allowing you to install any combination of AC, DC, analog, and specialty I/O modules in a single chassis according to your application needs.
Q4: What is the significance of the 1500V AC isolation rating?
A: This rating indicates a high level of electrical separation between the field wiring terminals and the module's internal logic circuits. It is a critical safety and reliability feature that protects the controller from voltage spikes, ground loops, and noise commonly present in industrial environments.
Q5: How do I wire field devices to this module?
A: Each of the 16 inputs has a terminal for the field wire. The field device (e.g., a limit switch) is connected between an AC hot line (120V AC) and the specific input terminal. The module's internal common is typically wired to the AC neutral. Always refer to the official Allen-Bradley wiring diagrams for precise instructions.
Q6: What happens if I apply a DC voltage to this AC input module?
A: Applying DC voltage to an AC input module is not recommended and will likely result in improper operation or damage. The module's internal circuitry is designed specifically for the alternating current waveform and frequency range specified.
Q7: Are spare parts or repair services available for this module?
A: As a trading company, Rossonix supplies new, genuine modules. For repair services, we recommend consulting specialized third-party industrial electronic repair centers. We focus on ensuring you have access to reliable replacement stock.
Q8: Do you provide technical documentation or manuals with the module?
A: While physical manuals may not be included with individual modules, we can direct you to the official Allen-Bradley publication resources where you can download comprehensive datasheets, user manuals, and installation guides for the 1746-IA16.
