Description

The 1794-OV16P is a high-density, 16-channel solid-state discrete DC digital output module designed for the Allen-Bradley Flex I/O 1794 platform. This module functions as a sinking switch array, providing a path to ground (0V DC reference) for up to 16 independent field-side loads, such as solenoid valves, relay coils, and pilot lamps. As a "Protected" (P) variant, it includes integrated electronic short-circuit, overcurrent, and thermal overload protection. The module supports Removal and Insertion Under Power (RIUP), allowing for maintenance and hot-swapping without requiring a system-wide power cycle.

Features

16 independent sinking (NPN) output channels.
Integrated electronic protection: automatic shutdown and recovery for short-circuits, overcurrent, and thermal overloads.
Supports RIUP (Removal and Insertion Under Power) for reduced downtime.
16 yellow status LEDs for local channel state verification.
Compatible with 1794-TB3 and 1794-TB3S terminal bases.
High-density design for space-constrained control cabinets.

Applications

The 1794-OV16P is widely used in industrial automation environments requiring reliable discrete control. Typical applications include driving interposing relays, small solenoid actuators, and status indicators in manufacturing, packaging, and process control systems. It is compatible with various Flex I/O communication adapters, including EtherNet/IP, ControlNet, and DeviceNet.

Installation Guidelines

Ensure the terminal base (1794-TB3 or 1794-TB3S) is securely mounted to a standard DIN-rail before installing the module.
Verify that the module is fully seated and locked into the terminal base to ensure proper backplane communication.
Maintain proper grounding practices for the 24V DC power supply to minimize noise interference.
Use shielded cabling for field I/O to prevent EMI/RFI issues in high-noise environments.
Handle with ESD precautions; avoid touching backplane pins.
Ensure adequate ventilation in the enclosure to keep ambient temperatures within the 0 to 55 degC range.

FAQ

Does this module require external fuses?

No, the 1794-OV16P is a "Protected" module. It features internal electronic protection that handles short-circuits and overcurrents automatically. Once the fault is cleared, the module will reset itself.

Can I hot-swap this module while the system is running?

Yes, this module supports Removal and Insertion Under Power (RIUP), allowing you to replace the unit without shutting down the entire Flex I/O rack.
