1734-OB2EP | Allen-Bradley POINT I/O Digital DC Sourcing Protected Output Module

Product Overview

The Allen-Bradley 1734-OB2EP functions as a high-performance digital output interface within the POINT I/O family. This module provides two sourcing output channels at 24V DC, allowing a PLC to drive field actuators, solenoids, and motor starters. Unlike standard modules, the "EP" designation indicates advanced electronic protection, which safeguards the hardware against short circuits and overcurrent conditions. We supply this unit in 100% Brand New condition, ensuring peak electrical resilience and immediate integration into your distributed I/O architecture.

Engineering Advantages

The 1734-OB2EP solves critical operational challenges by merging a compact footprint with intelligent power management:

• Superior Circuit Protection: The electronic protection mechanism monitors load conditions in real-time. It detects short circuits or excessive current draws and shuts down the affected channel instantly, preventing permanent damage to the module and reducing the risk of control-side electrical fires.

• High Current Density: Despite its small size, the module manages up to 4 Amps of total current. This high capacity allows engineers to drive larger loads directly without the need for interposing relays, saving significant cabinet space and reducing hardware costs.

• Efficient Thermal Management: The module limits thermal dissipation to 11.6 BTU/hour. This low heat output prevents temperature buildup in dense I/O racks, extending the lifespan of adjacent analog or communication modules.

• Hot-Swap Capability: The 1734-OB2EP supports Removal and Insertion Under Power (RIUP). Maintenance teams can replace a module without powering down the entire POINT I/O rack, drastically reducing MTTR (Mean Time To Repair) during critical production windows.

FAQs

• What makes the 1734-OB2EP different from the standard 1734-OB2?

  The 1734-OB2EP includes "Electronic Protection" (EP). While the standard OB2 relies on external fusing, the OB2EP features internal circuitry that automatically handles short circuits and overloads, providing a more robust safety layer for the system.

• Does this module require a specific terminal base?

  Yes. The 1734-OB2EP installs onto a 1734 terminal base, such as the 1734-TB or 1734-TBS. The terminal base provides the field wiring connections and the backplane interface.

• Is this a Brand New original product?

  Yes. We guarantee that this 1734-OB2EP is 100% Brand New and original. Using new components ensures that the electronic protection circuits have never been stressed by previous field faults.

• How do I reset the electronic protection if a fault occurs?

  Once you clear the external short circuit or overload, the module typically requires a power cycle or a software reset through the controller to resume normal operation, depending on your specific Logix configuration.
