Description
Product Name: 1746-F1 Allen Braley Output module
Product details:
The Allen-Bradley 1746-FI (often referred to as the 1746-F1) is a specialized Fast Analog Input Module belonging to the SLC 500 family. It is designed specifically for high-speed data acquisition where standard analog modules are too slow to capture rapid process changes.
1. Product Description
The 1746-FI is a high-speed analog input module that provides two differential input channels. Unlike standard modules that might take milliseconds to update, the “Fast” designation indicates its ability to process signals with extremely low latency. It converts analog signals into digital values that can be used by SLC 500 processors (SLC 5/01, 5/02, 5/03, 5/04, and 5/05).
2. Technical Specifications
The following table outlines the core parameters of the module:
| Parameter | Specification |
| Number of Inputs | 2 Differential Channels |
| Input Ranges | ±10V DC, 1-5V DC, 0-5V DC, 0-10V DC |
| Resolution | 12-bit binary |
| Update Time | Approximately 400 $\mu$s for both channels |
| Isolation | 500V DC (continuous) between inputs and backplane |
| Backplane Current | 200mA at 5V DC; 40mA at 24V DC |
| Step Response | < 1ms to 95% of full scale |
| Input Impedance | > 1 M$\Omega$ |
3. Key Advantages
-
High-Speed Performance: Ideal for applications requiring sub-millisecond response times, such as motion control feedback or pressure spike monitoring.
-
Precision: 12-bit resolution ensures accurate data representation for sensitive industrial processes.
-
Reliability: Built with the rugged industrial standards of the SLC 500 line, featuring optical isolation to protect the processor from field-side surges.
-
Ease of Integration: Fits into any standard SLC 500 chassis and is easily configured via RSLogix 500 software.
4. Important Considerations (Precautions)
-
Module Placement: To minimize noise interference, avoid placing the 1746-FI next to high-voltage AC modules or heavy inductive loads (like motor starters).
-
Wiring: Use shielded twisted-pair cable for all analog signals. Ensure the shield is grounded at only one end (typically at the chassis) to prevent ground loops.
-
Power Supply: Ensure your SLC 500 power supply has sufficient current capacity on both the 5V and 24V rails to support this module along with others in the rack.
-
Compatibility: While compatible with most SLC 500 processors, always verify your firmware version in RSLogix 500 to ensure the I/O configuration supports the “FI” series.
5. Product Applications
The 1746-FI is typically used in scenarios where “standard” analog sampling is the bottleneck:
-
Plastic Injection Molding: Monitoring high-speed pressure changes during the injection phase.
-
Material Testing: Capturing peak force or tension in destructive testing equipment.
-
Turbine Control: Monitoring fast-changing rotational speeds or vibrations.
-
High-Speed Web Handling: Managing tension control in paper or film conversion lines.
