Description

The Allen-Bradley 1746-NO4V is a high-performance analog output module engineered for the SLC 500 control platform. It provides four independent voltage output channels, allowing the PLC to interface with and control external devices such as variable frequency drives (VFDs), servo controllers, and precision actuators. This module is specifically designed for applications requiring high-speed response and low-latency signal processing.

Features

  • Four voltage output channels supporting multiple ranges: +/-10V DC, 0-10V DC, 0-5V DC, and 1-5V DC.
  • High-speed parallel update time of 512 microseconds for all four channels.
  • Robust 500V DC isolation between the backplane and field wiring.
  • Designed for seamless integration into the SLC 500 chassis system.
  • Supports external 24V DC power supply for field device excitation.

Applications

The 1746-NO4V is ideal for dynamic motion control, rapid process adjustments, and industrial automation tasks where precise voltage signaling is required to drive external hardware. It is commonly utilized in manufacturing, packaging, and material handling systems that rely on the SLC 500 architecture.

Installation Guidelines

  • Ensure the SLC 500 chassis power is disconnected before installing or removing the module.
  • The module must be seated firmly in the chassis slot to ensure proper backplane connection.
  • Use shielded cabling for all analog signal wiring to minimize EMI/RFI interference.
  • Maintain proper grounding practices for the 24V DC power supply to ensure signal integrity.
  • Keep the module away from high-voltage power lines and sources of extreme electromagnetic noise.
  • Ensure adequate ventilation within the enclosure to maintain operating temperatures below 60 degC.

FAQ

Are the output channels isolated from each other?
No, the four output channels on the 1746-NO4V are non-isolated from each other, although the module provides 500V DC isolation between the backplane and the field wiring.

What is the update time for this module?
The module features a high-speed update time of 512 microseconds for all four channels updated in parallel.
