Product Description

The Allen-Bradley 1756-IA16 is a high-performance digital AC input module designed for the ControlLogix platform. This module provides 16 isolated input points, organized into two groups of eight, allowing for flexible monitoring of 120V AC field devices. It is engineered for industrial automation environments requiring reliable signal detection and integration within a ControlLogix chassis.

Features

Sixteen (16) digital AC input points.
Configurable input delay times of 9 or 18 milliseconds to filter signal noise.
Operates within a voltage range of 74 to 132V AC at 50/60 Hz.
Designed for seamless integration into 1756 ControlLogix I/O chassis.
Low power consumption with a backplane current draw of 100 mA at 5.1V DC.

Installation Guidelines

Ensure the ControlLogix chassis is powered down before inserting or removing the module.
Verify that the module is fully seated in the chassis slot and secured with the top and bottom latches.
Use appropriate shielded cabling to minimize EMI interference in high-noise industrial environments.
Observe proper wiring polarity and grouping as specified in the ControlLogix system manual.
Maintain adequate clearance around the chassis to ensure proper airflow and cooling for the module.

FAQ

What is the primary function of the 1756-IA16 module?

The 1756-IA16 is used to interface 16 discrete 120V AC input signals with a ControlLogix PLC system, converting field-level AC voltages into a format readable by the controller processor.

Can the input delay be adjusted?

Yes, the module supports programmable input delay times of either 9 or 18 milliseconds, which helps in debouncing signals or filtering out transient noise from field sensors.

How many points are in each isolated group?

The 16 inputs are divided into two isolated groups, with 8 points per group, allowing for segmented wiring configurations.
