The Allen-Bradley 1756-IC16 is a ControlLogix 16-Point Digital DC Input Module designed for industrial control applications. This module provides a reliable interface between DC input devices, such as sensors, push buttons, and limit switches, and the ControlLogix controller. It operates within a 30-60V DC voltage range (48V DC nominal) and features a sinking input configuration. The 1756-IC16 is engineered for high performance and durability in demanding factory environments, offering flexible configuration options, including selectable input filter times to reduce noise susceptibility. It installs into any available slot of a ControlLogix chassis and uses a Removable Terminal Block (RTB) for easy wiring and maintenance.
