Allen-Bradley 1769-OB32T CompactLogix 32-Channel Sourcing DC Output Module

Product Overview

The 1769-OB32T serves as a high-density digital output solution for the CompactLogix and MicroLogix 1500 controller families. This 100% Brand New original module provides 32 sourcing outputs, allowing engineers to command a vast array of 24VDC field devices from a single slot. By utilizing a sourcing configuration, the module supplies power directly to the load, simplifying circuit troubleshooting and enhancing safety in standard industrial architectures.

Technical Specifications

The 1769-OB32T integrates high-performance switching within a compact form factor:

Engineering Advantages

• Ultra-High Density for Space Optimization: The 32-point architecture doubles the output capacity compared to standard 16-point modules. This reduces the physical footprint of the PLC rack, enabling the use of smaller, more cost-effective enclosures in cramped factory environments.

• Optimized Thermal Management: Despite its high point count, the 1769-OB32T maintains stable operation up to 60°C. The "T" designation signifies enhanced thermal performance, ensuring the module handles rapid switching cycles without overheating adjacent components.

• Simplified Wiring with RTB Support: The module utilizes the 1769-RTBN18 removable terminal block. This allows maintenance teams to replace a module without disconnecting individual field wires, significantly reducing downtime during hardware upgrades or repairs.

• Ruggedized Industrial Design: With a 30g shock rating and 5g vibration resistance, this module withstands the mechanical stress of heavy machinery installations. It operates reliably near high-vibration equipment where lesser commercial-grade electronics fail.

FAQs

• Is this 1769-OB32T unit brand new or surplus?

  We offer only 100% Brand New original Allen-Bradley stock. Each module ships in its original factory packaging with a verified UPC (662074455355) to ensure full compliance with your quality standards.

• Does this module support sinking or sourcing loads?

  The 1769-OB32T is a sourcing module. It sources current from the VDC user supply to the output devices (loads). If your field devices require a sinking configuration, you must select a different module type.

• What is the maximum distance this module can be from the power supply?

  This module carries a distance rating of 8. You must install it within eight slots of a 1769 power supply to ensure adequate backplane voltage and signal integrity.

• Can I use this with a MicroLogix 1500 controller?

  Yes. The 1769-OB32T maintains full compatibility with the MicroLogix 1500 platform and the 1769 CompactLogix controllers, providing a versatile spare-parts solution for multiple legacy and modern systems.
