Product Introduction
The Allen Bradley 1756-IV32 ControlLogix Sourcing Input Module is a high-density digital input module designed for the ControlLogix automation platform. This 32-point module is divided into two groups of 16 points, providing reliable and electrically isolated digital input acquisition for industrial control systems.
The IV32 module is optimized for sourcing input applications, where the module supplies the positive voltage to detect input states from external devices such as switches, sensors, and pushbuttons. Its compact design allows efficient use of ControlLogix chassis slots, while its electrical isolation ensures protection against signal interference, ground loops, and transient voltage spikes.
This module is widely used in manufacturing, process automation, and material handling systems, where fast, deterministic digital input monitoring is required for safety, control, and sequencing operations.
