Allen Bradley 1771-0D16 — Isolated Output Module

The 1771-0D16 is an isolated output module produced by Allen Bradley. This module is part of the 1771 I/O (Input/Output) system, which is commonly used in industrial automation applications.

The 1771-0D16 module provides 16 points of isolated output channels. Each output channel is capable of switching an electrical load, such as a solenoid valve or motor, with a maximum current rating of 2 Amps. The module provides isolation between the output channels and the system power, ensuring that any voltage spikes or noise on the load side does not affect the system side.

The 1771-0D16 module operates within a voltage range of 85-132V AC or 170-265V AC, and requires a power consumption of 30 Watts. It is designed to be inserted into an Allen Bradley 1771 I/O chassis, which provides the necessary power and communication connections to the module.

The module communicates with the system controller through a backplane interface, allowing the controller to send commands to the module to switch the output channels on or off. The status of each output channel is also reported back to the controller, providing real-time feedback on the state of the outputs.
