Allen-Bradley 1794-OB32P FLEX I/O 32-Point Protected Sourcing Output Module

Product Overview

The Allen-Bradley 1794-OB32P functions as a high-density discrete output interface for the FLEX I/O platform. It provides 32 sourcing output channels in a single, space-saving module, enabling controllers to drive a vast array of solenoids, contactors, and indicators. The "P" designation signifies integrated electronic protection, which shields the module from damage during field-side faults. We supply this unit as 100% Brand New and Original, ensuring your distributed I/O architecture benefits from zero-hour reliability and factory-certified performance.

Technical Specifications

Engineering Advantages

• High-Density Output Control: The 1794-OB32P packs 32 sourcing outputs into a slim modular footprint. This high-density design significantly reduces the number of terminal bases and adapters required for complex machinery, effectively lowering the cost-per-point in your I/O architecture.

• Integrated Short-Circuit Protection: The "P" (Protected) circuitry detects overcurrent conditions on a per-channel basis. It automatically shuts down the affected channel to prevent internal module damage caused by field wiring shorts or failed actuators, minimizing downtime and maintenance costs.

• Superior Thermal Management: Despite its high channel count, the module limits power dissipation to 5.3W at maximum load. This efficient design prevents heat buildup in non-ventilated remote enclosures, ensuring long-term stability in harsh industrial environments.

• Flexible Power Grouping: The module organizes its 14A total capacity into two groups (Channels 0-15 up to 6A; Channels 16-31 up to 8A). This grouping allows engineers to isolate different load types or power segments within the same module, enhancing system safety and organization.

• Seamless Distributed Mounting: As part of the 1794 FLEX I/O series, the module snaps directly onto a DIN-rail terminal base near the machine's actuators. This distributed approach eliminates long, expensive wire runs back to the main control panel and reduces electromagnetic interference (EMI).

FAQs

• What is the difference between 1794-OB32 and 1794-OB32P?

  The 1794-OB32P includes built-in electronic protection. While the standard OB32 requires external fusing to prevent module destruction during a short circuit, the OB32P includes self-protecting circuitry that manages overcurrent events automatically.

• Which terminal base must I use with this module?

  You must use the 1794-TB32 or 1794-TB32S (spring clamp) terminal base. These 32-point bases provide the high-density termination points required for the 32-channel wiring map.

• Does this module support "Sinking" or "Sourcing" field devices?

  The 1794-OB32P is a Sourcing module. It provides 24V DC to your field devices. Consequently, you must connect your actuators to the common/ground rail of your power supply.

• Is the unit shipped in the original Allen-Bradley box?

  Absolutely. We guarantee this product is 100% Brand New. It arrives in its original factory packaging with all security seals intact, ensuring the highest level of reliability for your mission-critical processes.
