1734-OW2 Allen Bradley

Description

Product Name: 1734-OW2 Allen Braley Power module

Product details:

The Allen-Bradley 1734-OW2 is a part of the POINT I/O™ family, designed to be a compact, modular solution for distributed I/O. This specific module is a 2-channel digital output module featuring Form A (normally open) electromechanical relays.

1. Product Description

The 1734-OW2 provides two individually isolated relay outputs. It is ideal for applications where small loads need to be switched, or where the output voltage differs from the control voltage. Since it uses physical relay contacts, it can handle both AC and DC voltages.

2. Technical Specifications

3. Product Advantages

• Versatility: Capable of switching a wide range of AC and DC voltages, making it a “universal” output for different load types.

• Isolation: The relay contacts provide high electrical isolation between the control logic and the field load, protecting your PLC system from surges.

• Space-Efficient: The POINT I/O system is famous for its slim “slice” design, allowing you to fit more I/O into smaller control cabinets.

• Hot-Swappable: Supports Removal and Insertion Under Power (RIUP), meaning you can replace a faulty module without shutting down the entire system.

4. Safety and Installation Precautions

• Arcing and Lifespan: Because these are mechanical relays, switching highly inductive loads (like motors or large solenoids) can cause arcing. This significantly reduces the contact life. Use external surge suppressors (snubbers) for inductive loads.

• Current Limits: Ensure the total current across both channels does not exceed the module’s thermal limits (usually 4.0A total).

• Mounting Orientation: Proper ventilation is required. Ensure the module is mounted horizontally or vertically within the specified temperature ranges ($0$ to $55$°C).

• Wiring: Always double-check that the field power is disconnected before wiring the terminal base to prevent accidental short circuits.

5. Typical Applications

• Interposing Relay: Acting as a bridge between low-power PLC logic and high-power devices like motor starters.

• Signal Level Switching: Controlling dry contacts for third-party equipment (e.g., sending a “start” signal to a VFD).

• Mixed Voltage Loads: When a single I/O station needs to control one 24V DC solenoid and one 120V AC light simultaneously.

• Isolation Requirements: Situations where the field device ground must be completely separate from the PLC ground.
