Product Summary
This solid-state module delivers reliable switching for AC loads. The 1762-OA8 controls eight outputs with a wide operating voltage range. Engineers integrate this module easily into MicroLogix systems. It provides a compact, robust solution for demanding industrial environments.
Expert Technical Evaluation & Performance Review
The Allen-Bradley 1762-OA8 is a high-reliability solid-state output module. It uses eight AC triac outputs for silent, arc-free switching. This design ensures long service life in high-cycle applications. The module operates on a voltage from 85 to 265 Volts AC. It handles frequencies between 47 and 63 Hertz.
This module supports a maximum bus current of 115 mA. Its heat dissipation stays at a low 2.9 Watts. This efficiency reduces thermal stress on your control panel. The maximum voltage drop is only 1.5 Volts at 0.5 Amps. The minimum on-state current sits at 10 mA. These specs guarantee reliable switching for various actuators.
The module complies with NEMA ICS 2-230 standards. It also meets EN50081-2 and IEC1000-4-2 requirements. This compliance ensures robust electromagnetic compatibility. The operating temperature range spans 32 to 131 degrees Fahrenheit. This range suits most factory floor environments.
Product Procurement & Buyer Guide
Procurement managers should verify system compatibility before ordering. The 1762-OA8 integrates natively with MicroLogix controllers. It works with the MicroLogix 1100, 1200, and 1400 systems. This module simplifies your bill of materials for these platforms.
Application engineers value its compact dimensions. The module measures just 3.54 x 1.59 x 3.43 inches. It weighs only 0.5 pounds. This small footprint saves valuable panel space. The module uses an input power of 100 to 240 Volts AC. It requires no separate external power supply for the logic side.
This module features two commons for flexible wiring. It allows you to split the eight outputs into two groups. This feature simplifies control of different voltage zones. The finger-safe cover protects technicians during installation. Always keep this cover in place while wiring.
Step-by-Step Installation Guide
Follow these steps for a safe, reliable installation. First, mount the module on a proper metal panel. Ensure the surface is clean and well-grounded. Refer to Allen-Bradley’s wiring guidelines for best results.
Second, inspect the module for any metal fragments. Remove all debris before applying power. These fragments can cause serious damage to the circuits.
Third, connect your field wiring to the terminal block. Keep the finger-safe cover in place throughout this process. Remember that once removed, the cover cannot be reinstalled. The wires will physically prevent it.
Fourth, verify your AC supply voltage. The module accepts 85 to 265 Volts AC on its outputs. Confirm your load matches these specifications. Ensure the on-state current exceeds the minimum 10 mA threshold.
