Product Overview

The Allen-Bradley 1769-OB32T delivers high-density digital control for industrial automation systems requiring rapid response times. This module features 32 sourcing transistor outputs, allowing CompactLogix and MicroLogix 1500 controllers to command a vast array of solenoids, indicators, and actuators from a single slot. By utilizing solid-state switching rather than mechanical relays, the 1769-OB32T offers significantly higher cycle life and faster transition speeds. We supply this unit in 100% Brand New original condition, ensuring maximum reliability for your critical process and machine control sequences.

Engineering Advantages

The 1769-OB32T solves the challenge of high-density I/O requirements in modern, compact control cabinets through advanced solid-state engineering.

Massive 32-Point Density: This module doubles the output capacity of standard 16-point cards within the same 35mm physical width. This reduces the number of expansion racks and communication adapters required, effectively lowering the overall system footprint and cost.
Superior Solid-State Longevity: Unlike relay modules that suffer from mechanical wear and contact arcing, the 1769-OB32T utilizes transistors. This eliminates mechanical failure points and ensures millions of worry-free switching cycles, making it the preferred choice for high-frequency pulsing applications.
High-Speed Switching Performance: Transistor outputs react significantly faster than mechanical relays. This module provides the precise timing necessary for high-speed packaging, labeling, and sorting systems where millisecond delays impact production throughput.
Channel-to-System Isolation: The 750V DC isolation barrier safeguards your controller CPU from field-side electrical noise and transient voltage spikes. This protection ensures that external wiring faults do not damage the expensive processor or backplane.
Simplified Maintenance with RTBs: The module uses a high-density Removable Terminal Block. During a hardware swap, maintenance personnel remove the entire wired connector without loosening individual screws, which prevents wiring errors and minimizes downtime.

FAQs

Can the 1769-OB32T drive AC loads?

No. The 1769-OB32T is a DC-only module. It switches 24V DC sourcing power. To control AC loads, you must use a relay output module like the 1769-OW8 or 1769-OW16.
What does "Sourcing" mean for this module?

"Sourcing" indicates that the module provides the positive (+) voltage to the load. The other side of your field device must connect to the common (-) side of the 24V DC power supply.
Does this module require an external power supply for the outputs?

Yes. While the backplane powers the module's internal logic, you must connect an external 24V DC power source to the module's field-side terminals to power the 32 output points.
Is the 1769-OB32T compatible with the MicroLogix 1500?

Yes. The 1769-OB32T functions perfectly as an expansion module for the MicroLogix 1500 controller as well as all CompactLogix 1769-series controllers.
