The Allen-Bradley 1756-OB16 is a digital output module from the ControlLogix series of I/O modules designed by Rockwell Automation for use in industrial automation systems. This module is typically used to interface with field devices such as relays, solenoids, and other equipment requiring digital output control.

Overview

• Series: ControlLogix
• Module Type: Digital Output
• Family: 1756 I/O Modules
• Mounting Type: Plug-in (for use with a ControlLogix chassis)
• Channel Type: 16 discrete outputs

Specifications

• Output Type: Sourcing (voltage output)
• Voltage Range: 24V DC
• Current Rating: Each output can provide up to 0.5 A of current (each output point)
• Total Current: The module can supply a total current of 8 A maximum across all 16 outputs.
• Output Response Time: Typically 1 ms (the time it takes to respond to a command)
• Isolation: Each output is optically isolated from the system.
• Output Configuration: The module supports 16 individual outputs, each with its own associated status indicator (LEDs).
• Status Indicators: LED indicators are provided for each output to show the status (on/off).
• Bus Interface: Uses the backplane of the ControlLogix chassis to communicate with the controller.
• Diagnostics: Provides diagnostic data, including information about I/O faults or module failures.
• Temperature Range: Operational range is typically from 0°C to 60°C (32°F to 140°F).
• Certification: UL, CE, CSA, and other international certifications for industrial use.
• Enclosure Rating: Typically rated for use in standard industrial environments, but an additional enclosure may be required for extreme conditions.
