Overview
The Allen-Bradley 1769-IA16 is a 16-point digital input module from the CompactLogix Compact I/O family, engineered for distributed input signal conditioning in industrial automation systems. This module provides reliable AC digital input capability with a standard 120 VAC input range (79–132 VAC operating), making it suitable for legacy and modern industrial control applications.
Key Features
- 16 digital input channels — supports up to 16 discrete input points on a single module
- Compact form factor — DIN rail or panel-mount design for flexible cabinet layouts
- 20 ms input response time — both ON and OFF transitions for consistent signal detection
- Status LEDs — real-time visual feedback for each input channel
- Plug-in architecture — direct connection to CompactLogix 1769 chassis via standard interface
- Low power consumption — 115 mA at 5 VDC (0.575 W), minimal module heat dissipation
