Overview
The Allen-Bradley 5094-IA16 is a proven 16-point AC digital input module designed for the FLEX 5000 distributed I/O platform. This module integrates seamlessly into Rockwell Automation control architectures and provides robust AC signal acquisition for industrial automation, motion control, and process control applications. Operating at 120VAC nominal with wide voltage tolerance, it delivers reliable state detection across harsh factory environments.
Key Features
- 16 Digital Inputs – AC-rated inputs with individual LED status indicators for each point
- 120VAC Operation – Nominal 120V with wide acceptance range (74–132V AC)
- Fast Input Filtering – Configurable response times (1ms off-to-on, 10–20ms on-to-off)
- Module Status Indicators – Power status, module health, and per-point diagnostics
- EDS File Support – Full integration with Studio 5000 and Logix Designer (v31.00.00+)
- DIN Rail Mounting – Compact form factor for cabinet integration
