Information About 1746-NIO4I
The 1746-NIO4I belongs to the Allen-Bradley SLC 500 family and is designed for applications requiring both analog monitoring and analog control. It accepts voltage inputs from -10 to +10V DC and current inputs from -20 to +20 mA, with a 16-bit sigma-delta ADC for precise signal conversion. Its two current outputs support ranges of 0–20 mA with a 5% over-range capability, delivering fine resolution for actuator and control device operation. The module features high rejection ratios (105 dB common mode and 55 dB normal mode at 60 Hz) to reduce noise interference in industrial environments. With an update time of 512 microseconds for all channels and step responses of 60 ms for inputs and 2.5 ms for outputs, it ensures fast and accurate performance. The 1746-NIO4I has isolation tested at 500V between the field side and backplane, enhancing reliability. It consumes 55 mA at 5V DC and 145 mA at 24V DC from the backplane, supporting operation within 0–60 °C.
Key Features:
- Channel Configuration: Provides two analog inputs (voltage/current) and two analog current outputs in a single-slot module.
- Input Ranges: Voltage input range of -10 to +10V DC and current input range of -20 to +20 mA.
- Output Ranges: Current output range of 0–20 mA with 5% over-range capability for flexible device control.
- Resolution: 16-bit input resolution with ±1 LSB accuracy; 14-bit output resolution for precise analog signal handling.
- Conversion Technology: Utilizes sigma-delta ADC conversion with high repeatability and low non-linearity error.
- Signal Integrity: Features 105 dB common mode and 55 dB normal mode rejection at 60 Hz to minimize electrical noise effects.
- Update and Response: Aggregate update time of 512 µs with step response of 60 ms for inputs and 2.5 ms for outputs.
- Electrical Isolation: 500V isolation tested between field wiring and backplane for enhanced system protection.
The 1746-NIO4I delivers precision, speed, and noise immunity, making it suitable for analog monitoring and control in SLC 500 automation systems.
