The Allen-Bradley 1762-OF4 delivers precise analog control for modulating actuators. This module provides four single-ended output channels for your MicroLogix system.

Why Procurement Teams Choose This Module

This module drives modulating valves and VFDs with high accuracy. It supports both voltage and current outputs seamlessly.

  • The 1762-OF4 uses a 12-bit R-2R ladder DAC for reliable signal conversion. It achieves ±0.5% accuracy at 25 °C.
  • Engineers appreciate the 2.5 ms output update time. This speed ensures responsive closed-loop control for critical processes.
  • The module dissipates only 2.8 Watts of heat. This low thermal output simplifies cabinet cooling design.
  • You can install up to six modules with a MicroLogix 1200 controller. This expandability supports large application requirements efficiently.

    • A Practical Installation Guide for Engineers

    Proper mounting and wiring ensure reliable operation and long service life. Follow these steps based on official guidelines.

  • Mount the 1762-OF4 horizontally on a grounded metal panel. The DIN rail mounting tabs do not need extra grounding.

  • Use Belden 8761 shielded cable for all analog signal wiring. This cable protects the module from electrostatic discharge damage.
  • Connect the 24V DC input power carefully to the module. The module requires stable power for consistent analog output performance.
  • Configure each channel for voltage or current output as needed. The module supports ranges from 0-10V DC and 4-20 mA.

    • Expert Technical Performance Review

    The 1762-OF4 offers robust signal integrity for industrial control systems. Its design prioritizes accuracy and repeatability.

    Deep-Dive Technical FAQ for Engineers

  • What data formats does the module support? The 1762-OF4 accepts Raw/Proportional and Scaled-for-PID data formats. This flexibility simplifies integration with control logic.
  • Can I use this module with a MicroLogix 1100? Yes, it works with MicroLogix 1100, 1200, and 1400 controllers. You can install up to four modules with a 1100.
  • How does the output protection work? The module includes current limiting at ±32 mA. This protection prevents damage from accidental short circuits.
  • What is the typical output range? The full-scale analog range extends to 0-10.5V DC and 0-21 mA. This over-range capability allows for calibration headroom.
