The AB+1746-NO4V module is an I/O module designed for use with Allen-Bradley PLCs, specifically within the 1746-series of programmable logic controllers.

Product Name:

1746-NO4V

Product Description:

The 1746-NO4V is a digital output module designed for the Allen-Bradley SLC 500 series of PLCs. It features 4 relay output channels that can handle both AC and DC loads. This module is used to control devices such as lights, motors, and other machinery components by sending out control signals from the PLC to external devices.

Product Parameters and Specifications:

• Type: Digital Output Module
• Number of Outputs: 4
• Output Type: Relay
• Output Voltage Rating: 24V DC (nominal) or AC
• Output Current Rating: 2 A per channel (max)
• Isolation: 1500V RMS between field and logic
• Response Time: Approximately 15 milliseconds (typical)
• Mounting: Designed for mounting on the SLC 500 chassis
• Connector Type: Removable terminal block
• Operating Temperature Range: 0°C to 60°C (32°F to 140°F)
• Storage Temperature Range: -40°C to 85°C (-40°F to 185°F)
• Relative Humidity: 5% to 95% non-condensing

Product Use:

The 1746-NO4V module is used to provide control signals to various field devices. It is commonly used in industrial automation systems to:

• Turn on/off electrical devices such as solenoids, relays, and motors.
• Activate or deactivate equipment based on logic programmed in the PLC.
• Interface with external systems requiring high current outputs.

In a typical setup, the 1746-NO4V module would be installed in a rack with other I/O modules and connected to a PLC processor. The PLC program will then control the output channels based on the logic or conditions defined in the control sequence.

Additional Notes:

• Ensure that the module’s voltage and current ratings match the requirements of the devices being controlled to avoid damage.
• Proper wiring and installation practices should be followed to ensure reliable operation and safety.
