Rossonix Co., Limited is proud to offer the Allen-Bradley 1746-NI16I SLC500 System Analog Input Module. As a trusted supplier with over a decade of experience in industrial automation components, we ensure every module we deliver meets rigorous quality standards. The 1746-NI16I is designed to provide precise analog signal acquisition for your SLC 500 control system, enabling reliable monitoring and control of process variables such as temperature, pressure, and flow. With 16 differential input channels and high-resolution 16-bit conversion, this module delivers exceptional accuracy and noise immunity, making it an essential component for demanding industrial applications.

Key Features and Technical Specifications:

16 Differential Analog Inputs – Capable of accepting voltage (0-10V, ±10V) or current (0-20mA, 4-20mA) signals, configurable per channel via software.
16-bit Resolution – Provides high precision for critical measurement tasks, with a typical accuracy of ±0.1% of full scale.
Channel-to-Channel Isolation – Ensures signal integrity and protects against ground loops and electrical noise, enhancing system reliability.
Fast Update Rate – Supports scan times as low as 1 ms per channel (depending on filter settings), enabling real-time data acquisition.
Backplane Power Supply – Operates on 5V DC from the SLC 500 chassis, simplifying installation and reducing external wiring.
Compact Form Factor – Occupies a single slot in the SLC 500 rack, maximizing I/O density.
Wide Operating Temperature Range – Rated for 0 to 60°C, suitable for most industrial environments.
LED Status Indicators – Front-panel LEDs for module status and channel diagnostics, simplifying troubleshooting.

Frequently Asked Questions (FAQ)

Q: Can the 1746-NI16I module be used with 2-wire transmitters?
A: Yes, the module accepts 4-20mA signals from 2-wire transmitters when properly wired. Please refer to the user manual for wiring guidelines.
Q: Does this module require external power supply?
A: No, it draws 5V DC directly from the SLC 500 backplane. No external power source is needed.
Q: How many channels can be configured as current inputs?
A: All 16 channels are independently configurable as voltage or current inputs via software (RSLogix 500).
Q: Is the module compatible with the SLC 5/01, 5/02, 5/03, 5/04, and 5/05 processors?
A: Yes, the 1746-NI16I is compatible with all SLC 500 processors that support analog I/O modules.
Q: What is the typical update rate for all 16 channels?
A: With a 10 Hz filter setting, the scan time is approximately 1 ms per channel, so a full scan of all 16 channels takes about 16 ms. Slower filter settings increase scan time but improve noise rejection.
Q: Does the module provide isolation between input channels?
A: Yes, it offers 500V AC channel-to-channel isolation and 1500V AC channel-to-backplane isolation.
Q: Can I use this module for thermocouple or RTD measurements?
A: No, the 1746-NI16I is designed for standard voltage/current signals. For thermocouples or RTDs, you would need a dedicated thermocouple or RTD input module.
Q: What warranty do you offer on this module?
A: We provide a standard warranty period (typically 12 months) against manufacturing defects. Extended warranty options are available upon request.
