Allen-Bradley 1756-IB16 /A ControlLogix 16-Point 24V DC Digital Input Module
Product Description
The Allen-Bradley 1756-IB16 /A is a high-reliability ControlLogix® digital input module designed to interface 24V DC field-side signals with industrial automation controllers. This Series A module features 16 sinking input channels, organized into two isolated groups of eight, providing an effective interface for common field devices such as proximity sensors, limit switches, and photoelectric eyes.
Engineered for high-speed industrial environments, the 1756-IB16 /A supports advanced features including Change-of-State (COS) detection and programmable digital filtering. These capabilities allow the module to report data transitions to the controller independently of the RPI (Requested Packet Interval), significantly reducing latency for critical event triggers. The module’s robust backplane communication and integrated hardware diagnostics ensure maximum system uptime and simplified troubleshooting.
