Features:
- Embedded Diagnostics for Reduced Downtime
- High Surge Current Tolerance for Demanding Loads
- Global Certifications and Hazardous Location Approval
The Allen‑Bradley 1756‑OA8D/A integrates advanced diagnostic capabilities including off‑state detection, output verification, pulse testing, and field power loss monitoring with zero‑cross tracking. These built‑in diagnostics allow engineers to remotely identify failed outputs or missing AC field power, and the module provides time‑stamped fault data with ±1 ms accuracy. As a result, the Allen‑Bradley 1756‑OA8D/A significantly reduces unplanned downtime and simplifies maintenance in critical control systems.
Designed to handle inrush currents from solenoids, relays, and pilot lights, the Allen‑Bradley 1756‑OA8D/A supports a surge current of 8 A for 43 ms per point, recurring every 2 seconds at 30 °C. Each output point is rated at 1 A continuously, with a total module current of 8 A at 30 °C that linearly derates at higher temperatures. This robust output capability makes the Allen‑Bradley 1756‑OA8D/A a reliable choice for controlling a wide range of AC loads without external suppression components.
The Allen‑Bradley 1756‑OA8D/A holds multiple international certifications including cULus, CE, RCM, FM, KC, UKCA, and Moroccan compliance, and is approved for use in Class I Division 2 Group A,B,C,D hazardous locations. These certifications confirm that the Allen‑Bradley 1756‑OA8D/A meets stringent industrial safety, EMC, and environmental standards such as EN 61131‑2 and EN 61000‑6‑2/4. For global machine builders and end users, this ensures regulatory acceptance and reduces project risk across different regions.
The 1756-OA8D/A Allen-Bradley ControlLogix Output Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
