Power Supply	5 VDC from SLC500 backplane (typical 1.0 A)
Isolation	Optical isolation between inputs and backplane

Detailed Product Advantages

High Precision: 16-bit resolution ensures accurate reading of analog signals, reducing measurement error and improving control quality.
Flexible Signal Compatibility: Supports both voltage (0-10V, ±10V) and current (4-20mA) inputs, allowing integration with a wide range of sensors and transmitters.
Robust Noise Rejection: Differential input architecture with excellent common mode rejection minimizes electrical interference in industrial environments.
Easy Integration: Directly plugs into any SLC500 chassis, no additional wiring or configuration software required beyond the standard RSLogix 500 environment.
Diagnostic Indicators: Onboard LED status lights for each channel and module health simplify troubleshooting.
Compact Design: Saves valuable rack space while providing eight channels in a single slot.

Benefits for Your Operations

Increased System Reliability: Rockwell Automation’s legacy SLC500 series is known for long-term stability; using genuine 1746-NI8 modules reduces the risk of downtime.
Cost Savings: The 8-channel design eliminates the need for multiple lower-density modules, reducing inventory and installation costs.
Improved Process Control: Faster, more accurate data acquisition leads to tighter control loops in temperature, pressure, flow, and level applications.

Frequently Asked Questions

Q: Can the 1746-NI8 be used in a SLC 5/03 processor system?
A: Yes, the 1746-NI8 is compatible with all SLC500 processors (5/01 through 5/05) as long as the chassis has an available slot and sufficient backplane power.
Q: What is the maximum analog input cable length?
A: For optimal noise immunity, keep the input wiring less than 100 meters (328 feet). Shielded twisted-pair cable is recommended.
Q: Does the module require external power for the current loop?
A: For 4-20 mA inputs, you need an external 24 VDC loop supply. The module itself is powered by the backplane and uses an external precision resistor (250 Ω) to convert current to voltage.
Q: How do I configure the input range?
A: The 1746-NI8 is software-configurable through the SLC500 programming software (e.g., RSLogix 500). You can select voltage or current mode per channel using the module’s data table.
Q: Is the module hot-swappable?
A: No, the SLC500 series does not support hot-swapping. Power down the chassis before inserting or removing the module.
Q: What is the typical update time for all eight channels?
A: The module updates all channels in approximately 18.5 ms (when using 60 Hz filter). Faster update rates are possible with lower filter frequencies.
Q: Does Rossonix provide warranty and technical support?
A: Yes, we offer a 12-month warranty against manufacturing defects and free basic technical support via email. Extended warranty options are available upon request.
