Product Overview

The Allen-Bradley 1769-OB32 provides high-density, solid-state digital control for CompactLogix and MicroLogix 1500 controller platforms. This module features 32 independent sourcing (PNP) outputs, enabling precise command of 24V DC industrial loads such as pneumatic solenoids, interface relays, motor starters, and indicator panels. We supply this unit as 100% Brand New original equipment, offering a space-saving solution for modern automated assembly lines and high-speed packaging machinery.

Engineering Advantages

• Maximize Panel Efficiency: The high-density 32-point architecture doubles the I/O capacity compared to standard 16-point modules without increasing the physical width. This allows engineers to shrink control cabinet sizes and reduce overall system costs.

• High-Speed Switching Response: With a turn-on delay of just 0.1 ms, the 1769-OB32 executes rapid logic transitions. This speed makes it the ideal choice for high-speed sorting, bottling, and motion-synchronized assembly applications.

• Robust Optical Isolation: Every channel utilizes optical isolation to separate the field-side 24V DC power from the sensitive backplane logic. This barrier prevents electrical transients and ground loops from compromising the CPU or adjacent modules.

• Thermal Management Flexibility: The module supports up to 0.5 A continuous current per point at 30°C. Advanced derating curves allow for reliable operation up to 60°C, ensuring performance even in poorly ventilated or high-temperature industrial environments.

• Simplified Wiring Integration: The 1769-OB32 works seamlessly with 1769-RTP32 remote terminal panels. Using pre-wired cables reduces manual wiring time and eliminates errors during large-scale commissioning.

FAQs

• Does the 1769-OB32 support sinking or sourcing loads? The 1769-OB32 uses sourcing (PNP) logic. It provides power from the module terminal to the load. Ensure your field devices (valves, relays, etc.) are compatible with a sourcing configuration.

• Can I use this module with a MicroLogix 1500 controller? Yes. The 1769 Compact I/O series is the primary expansion platform for the MicroLogix 1500. The module connects directly to the expansion port or another 1769 I/O module.

• Is a terminal block included with the module? This module typically requires a separate purchase of a terminal block (such as the 1769-RTBN18) or a pre-wired cable assembly. Check your specific order configuration to confirm if the terminal block is included.

• How does the module handle high surge currents from solenoids? The 1769-OB32 accommodates a surge current of 2.0 A per point for up to 10 ms. This surge capacity allows the module to handle the initial inrush required to energize pneumatic solenoids and larger relay coils without tripping.
