Description

Allen-Bradley 1771-OFE2 4-Point Analog Output Power Module

The Allen-Bradley 1771-OFE2 is a 4-channel analog output module designed for integration within the 1771 I/O series, specifically tailored for PLC-5 systems. This module delivers precise and reliable analog signals, making it ideal for controlling various industrial devices and processes.

Key Features

  • Output Channels: Four individually isolated analog outputs.
  • Output Signal: 4–20 mA current range.
  • Resolution: 12-bit digital-to-analog conversion.
  • Isolation: 1000V isolation per channel, ensuring signal integrity and safety.
  • Installation: Occupies a single slot in the 1771 I/O chassis, facilitating straightforward integration.
  • Power Requirements: Draws 1.5 A at 5V DC from the backplane, eliminating the need for an external power supply.
  • Thermal Dissipation: 26.9 BTU/hr, maintaining efficient operation without excessive heat generation.

Applications

The 1771-OFE2 module is versatile and can be employed in various industrial applications, including:

  • Controlling final control elements such as Variable Frequency Drives (VFDs), dampers, louvers, and valves.
  • Implementing outputs for Proportional-Integral-Derivative (PID) controllers to achieve automatic control of analog loops.
  • Transmitting signals to measuring, receiving, and recording devices like signal isolators, converters, panel meters, and data loggers.

Installation and Wiring

For optimal performance and safety, adhere to the following installation guidelines:

  • Use 12-gauge stranded or solid wire with an insulation thickness of 3/64 inch (1.2 mm); Belden 8761 cable is recommended.
  • Ensure module keying is set between positions 10 and 12, and 26 and 28, to prevent incorrect installation.
  • Secure wire terminations with a torque of 7–9 inch-pounds to maintain reliable connections.

Technical Specifications

  • Backplane Current: 1.5 A at 5V DC.
  • Power Dissipation: 7.9 Watts.
  • Channel Update Time: 8 milliseconds per 4 channels for BCD; 1.6 milliseconds per 4 channels for Natural Binary.
  • Operating Temperature: 0°C to 60°C.
  • Certifications: UL, CE, CSA.

The Allen-Bradley 1771-OFE2 module stands as a robust solution for precise analog output control in industrial automation systems, ensuring reliability and accuracy across various applications.
