The Allen-Bradley 1769-OB32T is a high-density digital DC output module designed for the CompactLogix™ and MicroLogix™ 1500 platforms. Featuring 32 solid-state sourcing outputs in a single-slot width, it is engineered for applications requiring a high number of control points within a limited physical space. This module is ideal for driving small-signal loads, such as interface relays, indicator lights, and low-power solenoid valves in automated assembly lines and process control systems.

Key Features
High-Density Architecture:Provides 32 independent output points in a single 1769 slot, significantly reducing the required rack space and the overall footprint of the control cabinet.
Solid-State Sourcing Logic:When an output is energized, the module "sources" current from the +24V DC supply to the field device. This is the standard interface for most modern PNP-compatible industrial components.
Fast Switching Response:Unlike mechanical relay modules, the solid-state design offers near-instantaneous response times and an unlimited mechanical life cycle, making it suitable for high-frequency switching tasks.
Diagnostic Status LEDs:Features 32 individual green LED indicators on the front panel, organized for quick visual confirmation of output logic states during commissioning and troubleshooting.
Removable Terminal Block (RTB) Compatibility:Supports high-density wiring solutions that allow for module replacement without disturbing the field-side wiring.
