Information About 1746-NO4V

The Allen-Bradley 1746-NO4V is a standard analog output module designed for use with both fixed and modular SLC 500 systems. It provides four non-isolated voltage output channels capable of generating analog signals between –10 and +10 VDC. These outputs are suitable for modulating actuators, signal retransmission, process control loops, coordinated control applications, and other automation tasks requiring precise analog voltage output. This module uses an R-2R ladder conversion method and offers 14-bit resolution, enabling accurate and repeatable signal generation. With an update time of just 512 microseconds for all channels, the 1746-NO4V supports fast-control applications where response time is critical. The module communicates using a 16-bit two’s complement format, and its outputs can be tied to PID loops, math-driven results, HMI/SCADA-controlled values, or external reference requirements.

Key Features:

  • Four-channel analog voltage output module
  • Output range: –10 to +10 VDC
  • 14-bit resolution for precise output control
  • Fast 512 µs update time across all channels
  • R-2R ladder digital-to-analog conversion
  • Factory calibrated with excellent accuracy stability
  • LED diagnostic indicators
  • Supports 16-bit two’s complement coding
  • Compatible with all SLC 500 modular chassis
  • RTB wiring for easy field installation
  • Four-channel SLC 500 analog voltage output module delivering –10 to +10 VDC for precise industrial control applications.

The 1746-NO4V draws 55 mA at 5V and 145 mA at 24V from the SLC backplane. It can alternatively use an external 24VDC power supply via SW1 if desired. For proper installation, the module should be mounted in a low-noise area of the chassis and away from AC or high-power modules. It is compatible with standard SLC 1746 chassis and includes LED status indicators and a removable terminal block for simplified wiring.

Frequently Asked Questions about 1746-NO4V
Question: What is the 1746-NO4V module?
Date Update:04/06/2025
Answer:

The 1746-NO4V is a 4-point analog output module for the SLC 500 family of controllers. This module provides 4 channels of 0-10V voltage output, which can be used to interface with devices such as valves, motor drives, and other industrial equipment that accept a voltage signal. It is designed to work with SLC 500 processors and provides a flexible solution for controlling analog devices in industrial automation applications.

  • Analog Output Channels: 4 channels of 0-10V analog output.
  • Output Range: The output voltage can range from 0V to 10V.
  • Resolution: 12-bit resolution per channel.
  • Accuracy: Typically ±1% of full scale.
  • Response Time: Typically 50 ms for full scale output.
  • Power Supply: Powered by the SLC 500 chassis with a 24V DC input.
  • Communication: Connects to the SLC 500 processor via the chassis backplane.
  • Operating Temperature: Typically 0°C to 60°C (32°F to 140°F).
Question: What types of devices can the 1746-NO4V module control?
Date Update:04/06/2025
Answer:

The 1746-NO4V module can control any device that accepts an analog 0-10V voltage input. Typical devices include:

  • Valves: Used in process control applications where precise control of flow or position is needed.
  • Motor Drives: Controlling the speed or position of a motor using a voltage signal.
  • Actuators: For controlling pneumatic or hydraulic systems in industrial machinery.
  • Analog indicators: For use in displays or other visual indicators of system data.

Ensure that the devices being controlled are compatible with 0-10V voltage inputs.

Question: Where can I find the user manual for the 1746-NO4V module?
Date Update:04/06/2025
Answer:

The user manual for the 1746-NO4V module can be found on the official Rockwell Automation website. You can search for 1746-NO4V in the Product Documentation section to download the manual in PDF format. The manual contains detailed information on wiring, configuration, troubleshooting, and specifications for the module.

Question: How do I configure the 1746-NO4V module?
Date Update:04/06/2025
Answer:

To configure the 1746-NO4V module, you need to use RSLogix 500 (or Studio 5000 for newer systems) to set up the configuration:

1. Add the Module to the Configuration:

  • Open your project in RSLogix 500 or Studio 5000.
  • Add the 1746-NO4V module to the I/O configuration of your SLC 500 processor.

2. Define the Output Channels:

  • Configure the output ranges for each of the 4 channels (typically 0-10V).
  • In RSLogix 500, you will assign each channel a specific tag or memory location that corresponds to the output value.

3. Set Up Scaling:

  • Define how the values from the PLC logic will be converted to the corresponding 0-10V output range. This may involve scaling the digital values from the PLC to match the output voltage.

4. Download the Configuration:

  • Once the module is configured, download the settings to the SLC 500 processor.
  • Test the configuration by verifying that the voltage output is correct for each channel and corresponds to the values set in the logic.
