Information About 1756-OA16I

The 1756-OA16I belongs to the ControlLogix I/O platform from Allen-Bradley and is engineered to handle AC output devices operating between 74 and 265 VAC. Each of its 16 output points is electrically isolated, allowing independent operation and reducing the risk of cross-channel interference. The module supports up to 1 A per point and features onboard status indicators for output state, communication, and overall module health. Designed for chassis installation, it works with standard ControlLogix removable terminal blocks such as the 1756-TBCH or 1756-TBS6H. With high isolation levels, wide operating temperature range, global certifications, and compatibility with Logix controllers, the 1756-OA16I is ideal for demanding automation environments requiring dependable AC output switching.

Key Features:

  • Isolated Outputs: Sixteen individually isolated AC output points for improved safety and noise immunity.
  • Wide Voltage Range: Supports 74–265 VAC output at 50/60 Hz for direct control of high-voltage loads.
  • Status Indication: LED indicators provide output status, communication activity, and module health diagnostics.
  • High Isolation Rating: 250 V continuous isolation between output channels enhances protection and reliability.
  • Flexible Wiring: Compatible with 1756-TBCH and 1756-TBS6H removable terminal blocks for simplified installation.
  • Chassis-Based Design: Fits any standard ControlLogix chassis slot for easy system integration.
  • Industrial Performance: Operates from 0 to 60 °C, suitable for a wide range of industrial environments.
  • Global Compliance: Certified to CE, UL, CSA, KC, Marine, and other international standards.

The 1756-OA16I provides the durability and accuracy required for AC output switching in advanced industrial automation systems.

Frequently Asked Questions about 1756-OA16I
Question: What is the main purpose of the 1756-OA16I module?
Date Update:05/06/2025
Answer:

The Allen-Bradley 1756-OA16I is a ControlLogix discrete output module designed for AC applications. It provides 16 individually isolated outputs for switching 120/240V AC loads. The module is used to control actuators, relays, lights, or any AC-powered equipment that requires on/off control. Each output can be configured independently to meet specific system requirements. It is ideal for use in industrial automation and process control systems.

Question: What is the operating voltage range for this module?
Date Update:05/06/2025
Answer:

The 1756-OA16I operates within a voltage range of 74 to 265 Volts AC. It supports both 120 VAC and 240 VAC nominal voltages at frequencies of 47–63 Hz. This wide operating range makes the module compatible with standard global power systems. The flexible voltage handling also simplifies design in multi-region installations. It allows for reliable operation even with power supply variations.

Question: What is the output delay time of this module?
Date Update:05/06/2025
Answer:

The output delay time for the 1756-OA16I is 9.3 milliseconds at 60 Hz and 11 milliseconds at 50 Hz. This applies to both ON-to-OFF and OFF-to-ON transitions. The consistent timing behavior makes it suitable for applications where predictable switching is essential. Although it is not suitable for high-speed switching, it performs reliably for general AC control. Delay values must be accounted for in time-critical processes.

Question: What type of terminal blocks is required for this module?
Date Update:05/06/2025
Answer:

The 1756-OA16I uses removable terminal blocks (RTBs) for electrical connections. It is compatible with the 1756-TBCH and 1756-TBS6H terminal blocks. These RTBs allow easy module replacement without rewiring. They support clean and organized installation and simplify maintenance. Selection of the correct RTB ensures proper wiring and secure operation.

Question: Is the 1756-OA16I module still in production?
Date Update:05/06/2025
Answer:

Yes, as of the latest available information, the 1756-OA16I module remains in active production by Rockwell Automation. It continues to be available through authorized distributors and is part of the standard ControlLogix catalog. However, users are encouraged to confirm lifecycle status on the Rockwell website. For long-term projects, reviewing migration strategies is a good practice. Staying informed helps avoid supply issues due to lifecycle changes.
