Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The 1756-IA8D is an Allen-Bradley ControlLogix diagnostic AC input module that provides eight diagnostic inputs grouped into two groups of four. It accepts 120 V AC signals and integrates into a ControlLogix rack via the backplane. It is used for monitoring field power status (loss-of-field diagnostics) and discrete AC inputs in industrial control systems. Typical applications include power-monitoring in machinery control panels, diagnostic input for safety-related systems, and integration into ControlLogix-based process or discrete control architectures.
Best Suited For
- ControlLogix systems requiring diagnostic AC input monitoring
- Loss-of-field detection in motor control or safety circuits
- Machinery or panel installations in rack-based architectures
- Applications needing backplane-integrated discrete AC diagnostics
