1756-IB32 Allen Bradley Controllogix 32 Point Digital Input Module
The Allen Bradley 1756-IB32 is a high-density digital input module from Rockwell Automation's ControlLogix® 5000 series, designed for industrial automation systems. It provides 32 channels of 24V DC digital inputs to interface with field devices like pushbuttons, limit switches, proximity sensors, and relay contacts. As part of the ControlLogix platform, it supports modular scalability, channel-level diagnostics, and seamless integration with Rockwell's controllers and software.
Key Features
High-Density Inputs: 32 independent input channels organized into two groups of 16 points (Group 1: Channels 0-15; Group 2: Channels 16-31), each sharing a common terminal (COM).
Voltage Flexibility: Operates within a 10-31.2V DC range, with a nominal input voltage of 24V DC.
Surge Protection: Withstands a maximum 250mA surge current (decaying to <37% within 22ms) for robust performance in noisy environments.
Configurable Filtering: User-adjustable input filter times (0, 1, 2, 9, or 18ms for OFF-to-ON; 0, 1, or 2ms for ON-to-OFF) to suppress signal noise.
Opto-Isolation: Electrically isolates input channels from the backplane to prevent interference and enhance system stability.
Diagnostic Capabilities: LED indicators for input status, communication health, and module faults, enabling quick troubleshooting.
Hot-Swappable: Supports Removable Input/Output Processing (RIUP) for module replacement without system downtime.
