Allen-Bradley 1762-OB32T MicroLogix Output Module 32 Point 24VDC

Allen-Bradley 1762-OB32T MicroLogix High-Density Output Module

The Allen-Bradley 1762-OB32T is a MicroLogix high-density solid-state output module featuring 32 output channels in 2 isolated groups of 16. Operating from 10.2-26.4 V DC with 24 V DC nominal output, it delivers 0.5 A per channel and 4.0 A per module at 60°C. With 1200 V AC isolation and source wiring support, this module drives indicating lights, solenoids, and small DC motors. Weighing approximately 0.5 lbs (0.23 kg), it dissipates 3.4 W.

Technical Specifications

Installation & Field Application Guide

• Mount the 0.5 lb module in a flame-retardant enclosure with a rating of 5VA, V2, V1, V0, or equivalent for non-metallic enclosures.
• Use 22, 24, or 26 AWG wire for field connections. Source wiring configuration.
• Operates in Pollution Degree 2 environments at altitudes up to 6562 feet without derating.
• The enclosure interior must be accessible only by tool to prevent injury.

Why Choose the 1762-OB32T

• 32 outputs in 2 isolated groups for high-density DC output control.
• Source wiring simplifies connection to sinking field devices.
• 1200 V AC isolation protects the controller from field-side faults.
• Fast 0.5 ms turn-on delay supports high-speed switching applications.

Field Engineer FAQs

Q1: What is the difference between per-channel, per-group, and per-module current ratings?

A1: Each channel handles 0.5 A, each group of 16 channels handles 2.0 A total, and the entire module handles 4.0 A total at 60°C.

Q2: Can this module drive AC loads?

A2: No, it is a DC output module. AC loads require interposing relays or circuitry between the module and the load.

Q3: What is the minimum load current for reliable operation?

A3: The minimum on-state current is 1 mA. Loads below this may not switch reliably.
