1734-OW2 | Allen-Bradley | POINT I/O 2-Point Relay Output Module

Product Overview

The Allen-Bradley 1734-OW2 serves as a high-density, electromechanical relay output solution within the POINT I/O 1734 family. This module integrates two independent Form A (Normally Open) relays, allowing the control of various AC and DC loads in a distributed I/O architecture. We provide this component as 100% Brand New original factory stock. It bridges the gap between low-level PLC logic and high-power field devices like motor starters, solenoid valves, and indicators while minimizing panel space.

Technical Specifications

Engineering Advantages

• Optimized for Mixed Loads: The 1734-OW2 handles both AC and DC voltages up to 240V AC or 125V DC. This flexibility eliminates the need for separate interposing relays when controlling diverse field equipment, significantly reducing system complexity.

• Granular Scalability: The "POINT" architecture allows users to add precisely two relay points per module. This prevents the "over-provisioning" of I/O commonly seen with 8 or 16-point cards, lowering the overall cost-per-point in small-scale automation skids.

• Robust Galvanic Isolation: 250V continuous isolation protects the sensitive backplane electronics from field-side voltage spikes and electrical noise. This barrier ensures that a catastrophic failure on the load side does not propagate to the PLC processor.

• Rapid Maintenance Architecture: The module utilizes a "T-Base" terminal system (sold separately), which allows for "Removal and Insertion Under Power" (RIUP). Maintenance teams can swap a 1734-OW2 module without disturbing the field wiring or shutting down the entire I/O rack.

• Extreme Cold Start Capability: Unlike standard commercial electronics, the 1734-OW2 operates down to -20°C. This makes it suitable for unheated enclosures in outdoor applications or cold storage facilities.

FAQs

• Can I use the 1734-OW2 for high-speed switching applications?

  No. The electromechanical design limits the switching frequency to 0.3 Hz (one operation every three seconds) at rated load. For high-speed PWM or rapid cycling, utilize a solid-state output module like the 1734-OB8.

• Does this module require a specific terminal base?

  Yes. You must install the 1734-OW2 on a 1734-TB or 1734-TBS terminal base. The base provides the mechanical connection to the DIN rail and the electrical interface to the POINTBus.

• How do I verify the contact health?

  The module includes a status LED for each output. If the LED illuminates but the field device does not activate, check the external fuse or the continuity of the electromechanical contact using a multimeter during a maintenance cycle.

• Is this a factory-sealed unit?

  Absolutely. We ship only 100% Brand New units in original Allen-Bradley boxes with intact serial numbers and factory documentation to ensure E-E-A-T compliance for industrial procurement.
