Allen-Bradley 1756-IA16 ControlLogix 16-Point 120V AC Digital Input Module
Product Description
The Allen-Bradley 1756-IA16 is a high-density ControlLogix® digital input module designed to interface 120V AC field signals with industrial automation controllers. Featuring 16 independent channels organized into two isolated groups of eight, this module provides superior noise immunity and wiring flexibility for monitoring switches, sensors, and relay contacts.
As a core component of the 1756 I/O platform, the 1756-IA16 supports Change-of-State (COS) detection and configurable digital filtering to minimize the impact of contact bounce or electrical interference. Its hardware-based signal processing ensures that AC transitions are captured reliably, while the module's diagnostic capabilities allow for real-time monitoring of backplane communication and field-side power status.
