Allen-Bradley 1771-OD16
16-Point Isolated AC Output Module for PLC-5 Systems
Overview
The 1771-OD16 is a 16-point isolated AC output module designed for use in PLC-5 systems within the 1771 I/O chassis family. It provides solid-state switching of AC loads using triac-based output circuits. Each output is individually isolated and capable of driving devices such as motor starters, pilot lights, solenoids, and other AC-powered actuators. The module incorporates zero-voltage turn-on to minimize electrical noise and inrush current, and includes built-in surge suppression for enhanced reliability in industrial environments.

Product Questions
-
Q: What types of loads can the 1771-OD16 control?
A: It is suitable for controlling AC-powered devices such as motor starters, pilot lights, solenoids, and contactors. -
Q: Does the module support inductive load suppression?
A: Yes. Each output includes MOV and RC suppression circuitry. Additional external suppression may be required for highly inductive loads. -
Q: Is the module hot-swappable?
A: No. Modules must be installed or removed with system power off to prevent damage or unsafe conditions. -
Q: What is the minimum load current requirement?
A: Each output requires a minimum load current of 5 mA to maintain proper operation. -
Q: Is the 1771-OD16 still available for purchase?
A: The module is discontinued. Availability is limited to surplus inventory and third-party suppliers.
