Information About 1771-OQ16

The 1771-OQ16 is part of the Allen-Bradley 1771 I/O module series for PLC-5 controllers, designed to expand system output capabilities with reliable isolated DC control. Operating at 10–32V DC, it supports both sink and source configurations, with each channel capable of 2A continuous current and a total module capacity of 32A. The module requires 400 mA of backplane current at 5V DC and integrates 18 LED indicators—16 for output status, one for fuse condition, and one for active status—to provide clear diagnostics. It is conformal-coated for durability, features modular hardware for space-efficient installation, and connects using the 1771-WH wiring arm. Compatible with most 1771 I/O chassis except the 1771-A1, A2, and A4, it supports keying to prevent incorrect placement. With typical signal delays of 45 ms for AC and 50 ms for DC, the 1771-OQ16 ensures reliable switching for general-purpose and isolated circuit applications.

Key Features:

  • Output capacity: 16 isolated DC outputs supporting sink or source wiring for flexible applications.
  • Voltage range: Operates within 10–32V DC, making it suitable for standard industrial devices.
  • Current handling: Provides up to 2A per channel and 32A maximum per module for high-density loads.
  • Power requirement: Draws 400 mA at 5V DC from the chassis backplane for reliable operation.
  • Diagnostics: Equipped with 18 LED indicators, including 16 for outputs, 1 fuse blown indicator, and 1 active status LED.
  • Signal response: Typical signal OFF delay of 45 ms (AC) and 50 ms (DC) for controlled switching.
  • Installation: Compatible with most 1771 I/O chassis except models A1, A2, and A4, with keying between pins 22–24 and 32–34.
  • Wiring: Uses the 1771-WH wiring arm for secure and organized field terminations.
  • Durability: Conformal-coated for protection against dust, moisture, and industrial contaminants.
  • Application: Designed for relays, actuators, and other DC output devices in isolated and general-purpose circuits.

The 1771-OQ16 delivers the reliability and precision required for DC output control in Allen-Bradley PLC-5 automation systems.

Frequently Asked Questions about 1771-OQ16
Question: What is the primary function of the 1771-OQ16 module?
Date Update:23/05/2025
Answer:

The 1771-OQ16 is a 16-point isolated digital DC output module designed for PLC-5 systems. It controls the ON/OFF status of DC user devices such as motor starters, solenoids, and indicators.

Question: Does the module provide any status indicators?
Date Update:23/05/2025
Answer:

Yes, the 1771-OQ16 features 18 LED indicators: 16 for output status, one for fuse blown indication, and one for module active status.

Question: What are the key installation considerations for this module?
Date Update:23/05/2025
Answer:

Proper keying is essential to prevent incorrect module insertion. Keying bands should be placed between pins 22 and 24, and pins 32 and 34. Additionally, ensure the module is securely mounted and connected to the appropriate wiring arm (1771-WN).

Question: Can this module be used to drive inputs on other modules?
Date Update:23/05/2025
Answer:

Yes, outputs from the 1771-OQ16 can be wired to inputs of compatible DC input modules, such as the 1771-IQ16, to indicate status changes like turning on a motor starter.

Question: Is the 1771-OQ16 still being manufactured?
Date Update:23/05/2025
Answer:

No, the 1771-OQ16 was officially discontinued by Rockwell Automation on January 31, 2021, and is no longer available for sale. Rockwell Automation recommends migrating to newer control platforms that support modern I/O modules. For detailed migration strategies and assistance, refer to Rockwell Automation's Product Compatibility and Migration Solutions.
