Product Summary
The 1762-OB32T is a high-density solid-state output module for MicroLogix systems. It delivers precise control of 32 loads with a 24VDC nominal voltage. This module uses two isolated groups of sixteen channels each. Engineers trust it for reliable solenoid and indicator light activation.
Technical Evaluation & Procurement Guide
High-Density Output Architecture
The 1762-OB32T features exactly thirty-two sourcing outputs. This configuration uses two isolated output groups. Each group contains sixteen independent channels. This design simplifies wiring for complex machine sections. It also provides critical electrical separation between zones.
Electrical Performance Specifications
This module operates within a voltage range of 10.2 to 26.4 VDC. It uses a nominal 24VDC supply for standard loads. Each channel delivers a continuous current of 0.5 A at 60 °C. The module allows a maximum surge of 2.0 A for 10 ms. It dissipates only 3.4 Watts of heat.
Industrial Isolation and Safety
The module provides reinforced isolation between groups and the system. It withstands 1200V AC for 2 seconds or 1697V DC for 2 seconds. This insulation protects against ground loops and voltage spikes. It maintains reliable operation in Pollution Degree 2 environments.
Procurement Considerations for Engineers
Procurement managers must verify the exact catalog number 1762-OB32T. This module accepts wire sizes 22, 24, and 26 AWG. It requires an enclosure with a 5VA or V0 flame spread rating. The enclosure interior must be tool-accessible only. This ensures operator safety and regulatory compliance.
Installation and Wiring Logic
The module supports source wiring for standard 24VDC loads. Typical loads include solenoid valves and small DC motors. The turn-on delay is just 0.5 ms for rapid response. The turn-off delay is 4.0 ms for predictable de-energization. This speed suits high-cycle packaging and material handling applications.
Performance Review for Heavy Loads
The module maintains a minimum on-state current of 1 mA. This ensures reliable switching even with small pilot lights. The maximum off-state leakage is only 0.1 mA. The on-state voltage drop is 0.3 VDC at full load. This low drop improves energy efficiency in the control panel.
