Product Overview

The Allen-Bradley 1769-OV32T delivers high-density, solid-state digital control for CompactLogix and MicroLogix 1500 platforms. This module provides 32 independent sinking (NPN) output channels, specifically engineered for high-I/O applications where cabinet space is limited. The module organizes its 32 channels into two isolated groups of 16, allowing engineers to manage separate power circuits or multiple voltage sources within a single unit. We supply this module as 100% Brand New original factory stock, ensuring peak performance for precision switching of DC industrial loads.

Engineering Advantages

High-Density Output Concentration: The 1769-OV32T packs 32 sinking outputs into a standard Compact I/O footprint. This concentration allows designers to reduce the number of required I/O modules, significantly lowering both rack hardware costs and total cabinet dimensions.
Circuit Isolation and Safety: The dual-group architecture (16 channels per group) facilitates the separation of distinct field power circuits. This isolation prevents cross-circuit interference and allows for localized emergency stop or power-down configurations within a single module.
Ultra-Fast Signal Processing: With a turn-on delay of only 0.1 ms, this module supports high-speed automated packaging, high-frequency pulse applications, and rapid-response assembly line logic where timing is critical.
Optical Backplane Protection: Robust optical isolation separates the 24V DC field-side transients from the controller's internal backplane. This barrier protects the CPU and other sensitive modules from electrical noise, surges, and field-side wiring faults.
Thermal Reliability: The module manages heat effectively, providing 0.5 A per point at 30°C. Even in high-temperature industrial environments reaching 60°C, the module delivers 0.25 A per point, maintaining reliable switching for valves, solenoids, and relays.

FAQs

What is the difference between Sinking (NPN) and Sourcing (PNP) modules?

The 1769-OV32T is a Sinking (NPN) module, meaning it completes the circuit to ground (0V) for the field load. If your field devices require the module to provide the positive (+) voltage, you should select the Sourcing (PNP) version, such as the 1769-OB32.
Can I use the 1769-OV32T with different voltages for each group?

Yes. Because the two groups of 16 channels are isolated from each other, you can apply a 12V DC source to Group 1 and a 24V DC source to Group 2, provided both stay within the 10.2V to 26.4V DC operating range.
Is this a genuine Allen-Bradley product?

Yes. We sell this 1769-OV32T as 100% Brand New original equipment from Rockwell Automation. It comes in factory packaging and meets all OEM specifications.
What is the maximum distance the module can be from the power supply?

The 1769-OV32T has a power supply distance rating of 8 modules. You must install it within 8 slots of a 1769 power supply to ensure consistent voltage levels across the backplane.
