The 1794-OV32 is a high-density digital output module. Its core design philosophy is "flexibility and structure," and it is mainly used in the entire control system to receive logic instructions from the PLC and drive DC loads in the field.
High Density
Modular Design
Industrial Durability
The Allen-Bradley FLEX I/O system offers a flexible, modular, and cost-effective solution for your industrial automation and control. The space saving design offers rack based I/O functionality of up to eight modules and provides digital, analogue, HART analogue, and specialty I/O with 4...32 points per module with flexible mounting and wiring options.FLEXI/O is a Distributed I/O System that connects to several Networks including EtherNet/IP, ControlNet and DeviceNet. Flexible, low-cost, modular I/O for distributed applications. FLEX I/O offers all the functions of larger, rack-based I/O without the space requirements. Independently select the I/O, termination style, and network to meet your application needs.

Food & Beverage
Manages gate operations and conveyor status pilot lights on filling lines.
Semiconductor Equipment
Controls vacuum valves and cooling water switches in auxiliary systems of wafer processing equipment.
When using the 1794-OV32, prioritize its sinking output characteristics by ensuring correct load wiring polarity, and strictly limit both per-channel and total module current (4A) to prevent overheating. During physical installation, ensure the module is fully locked onto the terminal base and exercise caution during Removal and Insertion Under Power to avoid electrical arcing. Furthermore, given its high-density 32-point design, maintain proper heat dissipation and ventilation within the enclosure, while periodically checking the stability of the external 24V DC power supply to ensure logical reliability under heavy loads.
It is a high-density digital (discrete) output module from the Allen-Bradley FLEX I/O family, used to drive field devices based on controller commands.
How to use the 1794-OV32?
It is used by snapping it onto a compatible FLEX I/O Terminal Base (e.g., 1794-TB32). It then connects to a PLC via a communication adapter (like Ethernet or ControlNet).
What is the current capacity per channel for 1794-OV32?
Each channel supports a maximum current of 0.5A. If your load exceeds this value, an interposing relay may be required to protect the module.
How to check 1794-OV32 status via indicators?
There are multiple yellow LEDs on the front of the module. A lit LED means the channel output is ON, and an unlit LED means it is OFF.
Which terminal base should be used with 1794-OV32?
Since it is a 32-point module, it is typically used with the 1794-TB32 or 1794-TB32S terminal base to provide sufficient wiring terminals.
