Description

The Allen-Bradley 1771-OQ16 is a 16-point isolated digital output module designed for use within the 1771 I/O chassis system. This module provides reliable switching for DC-operated field devices, supporting a voltage range of 10-32V DC at 100mA per point. As an isolated output module, it offers enhanced flexibility for applications requiring independent circuit control or varied voltage potentials across output groups.

Features

  • 16 isolated output channels for versatile field device control.
  • Compatible with standard 1771 I/O chassis backplanes.
  • Operating voltage range of 10-32V DC.
  • Maximum output current of 100mA per channel.
  • Designed for industrial reliability in PLC control environments.

Applications

This module is commonly utilized in industrial automation systems for controlling actuators, relays, solenoids, and indicators. Its isolated design makes it suitable for complex control loops where electrical isolation between output channels or between the output and the backplane is required to prevent ground loops or cross-channel interference.
