Description
Product Name: 1734-OB2 Allen Braley Power module
Product details:
The Allen-Bradley 1734-OB2 is a compact, high-performance digital output module belonging to the POINT I/O™ family. It is designed to provide localized or distributed control within an industrial automation system, offering a space-saving design without compromising on reliability.
1. Product Overview
The 1734-OB2 is a 2-channel digital output module that provides sourcing (PNP) outputs. It is ideal for driving small solenoids, indicators, and actuators. Because it is part of the POINT I/O system, it is highly modular and can be easily integrated with various communication adapters (EtherNet/IP, ControlNet, DeviceNet).
2. Technical Specifications
Below are the key parameters for the 1734-OB2:
| Parameter | Specification |
| Number of Outputs | 2 Channels (Sourcing/PNP) |
| Operating Voltage | 24V DC (10-28.8V DC range) |
| Output Current Rating | 1.0A per channel (max); 2.0A per module (max) |
| On-State Voltage Drop | 0.2V DC maximum |
| Off-State Leakage Current | 0.5 mA maximum |
| POINTBUS Current | 75 mA @ 5V DC |
| Power Dissipation | 0.8 W maximum |
| Isolation Voltage | 50V (continuous), tested at 2500V DC for 60s |
| Terminal Base Unit | 1734-TB, 1734-TBS, 1734-TOP, or 1734-TOPS |
3. Product Advantages
- Modular Scalability: Its “slice” design allows you to add only the I/O you need, reducing hardware costs and cabinet space.
- Hot-Swappable: Supports Removal and Insertion Under Power (RIUP), allowing for maintenance without shutting down the entire system.
- Ease of Maintenance: Features clear LED indicators for network status and individual I/O status, making troubleshooting straightforward.
- Integration: Seamlessly integrates with Studio 5000 Logix Designer® via Add-On Profiles (AOP).
4. Key Considerations & Precautions
- Polarity: Ensure correct wiring for sourcing outputs. The module connects the load to the positive DC rail.
- Inductive Loads: When driving inductive loads (like relays or solenoids), ensure you use external surge suppression to protect the output circuitry from “flyback” voltage.
- Thermal Limits: If operating in high-temperature environments, ensure proper spacing and airflow as per the manufacturer’s derating curves.
- Terminal Base: This module requires a separate terminal base (e.g., 1734-TB) for wiring; it does not come with the base as standard.
5. Typical Applications
The 1734-OB2 is commonly used in various industrial sectors, including:
- Material Handling: Controlling small conveyor gates or diverters.
- Packaging: Actuating pneumatic valves and signaling lights.
- Assembly Lines: Driving small DC motors or status indicators on workstations.
- Food & Beverage: Distributed control in wash-down environments when placed in appropriate enclosures.
