Product Summary
The Allen-Bradley 1794-OB32P is a 32-channel discrete output module for the Flex I/O family. It provides electronic protection per channel. This module drives 24V DC loads like relays and indicators. It groups outputs into two isolated banks for flexible power distribution.
Product Procurement & Buyer Guide
Procurement engineers choose this module for its robust channel protection. The 1794-OB32P uses electronic fusing on each output. This design eliminates the need for external fuses. It reduces panel space and maintenance costs significantly.
You must select the correct terminal base for this module. It only works with the 1794-TB32 or 1794-TB32S units. Verify your existing base compatibility before ordering. This module mounts easily on a standard DIN rail.
The module splits its 32 outputs into two groups of 16. Channels 0 through 15 handle a total of 6 Amperes. Channels 16 through 31 manage a total of 8 Amperes. The maximum module current is 14.0 Amperes. Plan your load distribution across these banks carefully.
This module suits 24V DC sourcing applications perfectly. It drives pilot lights, buzzers, horns, and relay coils. It also controls solenoid valves and other inductive loads. Its fast output delay of just 0.5 ms ensures precise control.
Maintenance, Troubleshooting & Longevity Protocols
Maintain the 1794-OB32P with simple periodic visual checks. Inspect the 32 yellow status indicators for normal operation. A lit LED confirms the channel is active. A dark LED signals an off or faulted state.
The module resets automatically after a thermal overload. A sustained fault indicates a short circuit. Check the connected load and wiring immediately. Ensure the total channel current stays below 500 mA per output.
Keep the operating environment within the specified limits. The module works from 0 to 55 degrees Celsius. It withstands 5g vibration and 30g shock. Store the unit between -40 and 85 degrees Celsius for longevity.
