Features:

  • 16-point sinking DC output control with integrated electronic fusing per channel
  • 10-30V DC operational range supporting DC-13/SR pilot duty loads
  • Standard slot compatibility within the 1756 ControlLogix rack architecture
The 1756-OV16E/A operates as a ControlLogix Digital DC Output Module, providing 16 sinking current output points for discrete control of DC field devices within industrial automation systems. It continuously drives loads across a 10-30V DC operational voltage range, delivering up to 1A per point at DC-13/SR pilot duty ratings while maintaining nominal signal delays of 75μs for OFF-to-ON transitions and 360μs for ON-to-OFF transitions, with a maximum switching time of 1ms in either direction. Each output point incorporates individual electronic fusing to isolate overcurrent faults without requiring external protection devices, and the module supports a minimum load current of 2mA per point with a maximum leakage current of 1mA in the OFF state.

The 1756-OV16E/A provides essential discrete output functions within the ControlLogix rack, serving as a critical component of the I/O path that directly affects the proper operation of the overall control system. One or multiple 1756-OV16E/A modules may be installed per chassis depending on the required output density, with each module occupying a single slot in the 1756 ControlLogix rack.

For overload protection applications, the 1756-OV16E/A utilizes individual electronic fusing per output point rather than conventional mechanical fuses. The module continuously monitors current levels across all 16 channels, and if the system detects that an individual output has exceeded its rated capacity or encountered a sustained fault condition, the electronic fuse for that specific channel will isolate the affected point while preserving operation of the remaining outputs.

The 1756-OV16E/A Allen-Bradley Digital DC Output Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
The Allen-Bradley 1756-OV16E/A ControlLogix 16 Point D/O Module is a digital DC electronic fuse sinking output module designed specifically for industrial automation control systems. With its reliable performance and flexible configuration, it serves as a key component connecting the control and execution layers within the ControlLogix platform. The module supports a wide input voltage range of 10-30V DC and features 16 output channels, each capable of providing 1A of current. It efficiently drives various DC loads such as motor starters, solenoid valves, and indicator lights, and is widely applicable in manufacturing production lines, metallurgical equipment, chemical control systems, and other fields.

This 1756-OV16E/A module offers significant advantages in safety and maintainability. Employing an electronic fuse protection design, the 16 output channels are divided into groups of 8. When an abnormal situation such as overcurrent occurs in a channel, the electronic fuse can quickly respond to protect the load and the module, reducing the risk of escalation. Simultaneously, the ±1 ms diagnostic timestamp accuracy precisely records the moment of fault occurrence, helping maintenance personnel quickly locate the root cause of the problem and shorten downtime for repairs. Its 20-pin interface design and Series A stability ensure the module's connection reliability and long-term operational stability in complex industrial environments, providing strong support for the efficient and safe operation of automation systems.
