1746-NI8 A AB Redundant Power Supply Module 24 VDC At 300 MA (Max) 0 To 60 O C

 

1746-NI8 A Description

The Allen-Bradley 1746-NI8 is an analog input module from the SLC 500 programmable logic controller (PLC) system. This module acts as an interface between the SLC 500 backplane and analog sensors in the field, converting real-world analog signals (such as voltage or current) into precise digital values that the processor can understand. It is designed for industrial monitoring and control applications where measuring variables like temperature, pressure, level, or flow is required. The 1746-NI8 is known for its reliability and ease of configuration within the Rockwell Automation ecosystem.

1746-NI8 A Features

  • 8-Channel High Resolution:​ Provides eight independent analog input channels, allowing you to monitor multiple process points with a single module.
  • Selectable Input Range per Channel:​ Each channel can be individually configured for different input types (voltage or current), offering great application flexibility. Supported ranges include 0-10V DC, 0-5V DC, ±10V DC, 0-20 mA, and 4-20 mA.
  • Wide Operating Voltage Range:​ The module can be powered directly from the SLC 500 backplane, requiring no external power supply for basic operation.
  • LED Indicators:​ Features status LEDs for power and channel diagnostics, enabling quick troubleshooting and module health monitoring.
  • SLC 500 Compatibility:​ Designed to plug directly into any SLC 500 chassis (1746 series), ensuring seamless integration and communication with the SLC 5/0x processors.
  • 4-20 mA Input Support with Open Circuit Detection:​ Supports the industry-standard 4-20 mA signal type and can detect open wire conditions on current input channels.

1746-NI8 A Material & Application

  • Module Housing:​ Constructed from high-grade, flame-retardant plastic (thermoplastic).
  • Connector:​ The removable screw-terminal connector is typically made of industrial-grade plastic​ with metal (nickel or gold-plated) contacts​ for reliable connections.
  • Internal Electronics:​ The printed circuit board (PCB) contains various electronic components, including ICs, resistors, and capacitors, compliant with industrial standards.

1746-NI8 A Primary Applications:

  • Process Monitoring: Connecting to transmitters for pressure, temperature, flow, and level.
  • Machine Control: Reading analog signals from potentiometers, LVDTs, or load cells.
  • Data Acquisition: Logging analog sensor data for monitoring and analysis.
  • Water/Wastewater Treatment, HVAC Control, and General Manufacturing Automation.
