Allen-Bradley 1769-OB32T 32-Point Transistor Output Module – 1769 Compact I/O Series
When a transistor output module fails mid-production, the consequences are immediate and costly: conveyor lines halt, robotic arms freeze, and safety interlocks trip — all because 32 discrete output channels can no longer drive solenoids, motor starters, or indicator circuits. In high-throughput manufacturing environments, every minute of unplanned downtime translates directly into scrapped batches, missed delivery windows, and escalating maintenance costs. The Allen-Bradley 1769-OB32T is the precision component that keeps those 32 channels alive, reliable, and responsive — making it one of the most operationally critical modules in any Compact I/O rack.
Within the 1769 Compact I/O family, the 1769-OB32T occupies a high-density output position, offering 32 sourcing transistor outputs in a single compact slot — a density that reduces rack footprint while maximizing I/O capacity. Globally, the 1769 Compact I/O platform is deployed across hundreds of thousands of MicroLogix and CompactLogix control systems in automotive, food & beverage, material handling, and process industries, making the 1769-OB32T one of the most widely specified discrete output modules in the Allen-Bradley ecosystem.

Our Quality Assurance Process
At Konmask.com, every Allen-Bradley 1769-OB32T unit undergoes a structured verification process before shipment:
- Source Verification: Units are sourced from authorized distributors or verified surplus channels with full traceability documentation.
- Visual & Physical Inspection: Enclosure integrity, connector condition, label authenticity, and firmware revision labels are checked against Rockwell Automation reference standards.
- Functional Pre-Test: Where applicable, modules are bench-tested on a live 1769 rack to confirm output channel operation and backplane communication.
- Anti-Static Packaging: All modules are shipped in ESD-safe bags with foam cushioning inside double-wall cartons to prevent transit damage.
- Documentation Package: Each shipment includes a packing list, inspection record, and available datasheet or certificate of conformance upon request.

Frequently Asked Questions
Q: Is the 1769-OB32T compatible with CompactLogix L3x controllers?
A: Yes. The 1769-OB32T is fully compatible with all CompactLogix controllers that support the 1769 Compact I/O bus, including the L30E, L32E, L35E, and L35CR variants.
Q: What is the difference between 1769-OB32T and 1769-OB32?
A: The 1769-OB32T uses transistor (solid-state) outputs rated for 0.5A per point, while the 1769-OB32 is also a transistor output module but with different current ratings and group configurations. Always verify the exact catalog suffix against your application’s current and voltage requirements.
Q: Can I mix 1769-OB32T modules with relay output modules in the same rack?
A: Yes. The 1769 Compact I/O architecture allows mixing of different module types within the same rack, subject to total backplane power budget constraints.
