The Allen-Bradley 1746-NIO4V is a high-resolution analog combination I/O module engineered for the SLC 500 programmable controller platform. This 1746-NIO4V module integrates two differential analog inputs and two non-isolated voltage outputs in a single-slot form factor. The 1746-NIO4V inputs are configurable per channel for either -10 to +10V DC voltage or -20 to +20 mA current signals. With 16-bit input resolution, 14-bit output resolution, and a 512 µs update time, the 1746-NIO4V delivers precise signal conversion for demanding industrial automation applications.
Analog Signal Acquisition – Two differential input channels convert field sensor signals (voltage or current) into 16-bit digital values for the SLC 500 processor.
Analog Output Control – Two non-isolated voltage output channels convert digital commands from the processor into -10 to +10V DC control signals for actuators and final control elements.
Per-Channel Input Configuration – Each input channel is independently selectable for voltage or current mode, accommodating mixed sensor types within a single module.
Parallel Update – All channels update simultaneously within 512 µs, ensuring synchronized data acquisition and control.
Diagnostic Indication – Front-panel red LED indicates when the module is receiving 24V DC power and operating normally.
Factory Calibration – Module is factory-calibrated; no field calibration required under normal operation.
Space-Efficient Design – Combines both analog inputs and outputs in a single-slot module, conserving valuable chassis slots in SLC 500 systems.
Flexible Signal Compatibility – Per-channel configurable inputs accept both voltage and current signals, reducing the need for multiple dedicated modules.
High-Speed Performance – 512 µs update time and 2.5 ms output step response enable real-time control in time-sensitive applications.
Precision Measurement – 16-bit input resolution with 305 µV and 1.22 µA per LSB granularity delivers accurate signal acquisition.
Hazardous Location Ready – C-UL Listed for Class 1, Division 2 hazardous locations, expanding deployment options.
Simplified Wiring – Removable terminal block with shielded Belden #8761 cable recommendation facilitates installation and maintenance.
Industrial Process Control – Temperature, pressure, flow, and level monitoring with analog sensor inputs, combined with valve or actuator control outputs.
Machine Automation – Analog monitoring and control for material handling systems, packaging equipment, and conveyor operations.
Signal Conversion & Conditioning – Interfacing analog sensors and actuators with SLC 500 PLC systems for seamless data integration.
Building Automation – HVAC temperature regulation and humidity control applications.
Chemical & Pharmaceutical Processing – Precision analog I/O for batch process control in regulated industries.
Water & Wastewater Treatment – Flow measurement and pump control in municipal and industrial treatment facilities.
Power Generation – Monitoring and control of auxiliary systems in power plants.
Q1: What is the Allen-Bradley 1746-NIO4V used for?
The 1746-NIO4V is a 4-channel analog combination I/O module for SLC 500 systems. It provides two configurable analog inputs (voltage or current) and two voltage outputs, enabling precise signal acquisition from field sensors and control output to actuators in a single-slot module.
Q2: What types of input signals does the 1746-NIO4V accept?
The 1746-NIO4V accepts two types of analog inputs: -10 to +10V DC voltage signals or -20 to +20 mA current signals. Each of the two input channels is independently configurable for either mode.
Q3: How many outputs does the 1746-NIO4V provide and what type?
The 1746-NIO4V provides two non-isolated voltage outputs with a range of -10 to +10V DC. The outputs deliver 14-bit resolution with a step response of 2.5 ms.
Q4: What is the update time of the 1746-NIO4V?
The 1746-NIO4V updates all four channels simultaneously in 512 microseconds. The input step response is 60 ms, while the output step response is 2.5 ms at 95%.
Q5: What are the power requirements for the 1746-NIO4V?
The 1746-NIO4V draws 55 mA from the 5V DC backplane and 115 mA from the 24V DC backplane of the SLC 500 chassis. The module requires both voltages for proper operation.
