Product Overview

The Allen-Bradley 1756-IB16D is a ControlLogix digital input module with 16 diagnostic DC input channels. Designed for mounting on a ControlLogix backplane, it provides 12/24 V DC sink-type inputs with per-channel diagnostics. Typical applications include general discrete input monitoring, fault detection, and process control in industrial automation systems using ControlLogix platforms. Part number 1756-IB16D implements enhanced diagnostics compared to standard input modules.
