Description

The Allen-Bradley 1756-IH16ISOE is a high-performance Digital Isolated Input Module designed for the ControlLogix platform. This module features 16 individually isolated inputs with Sequence of Events (SOE) recording capabilities, making it ideal for applications requiring precise time-stamping of critical system changes. It is engineered to handle 125V DC sink/source signals within a robust operating range of 90-140V DC, ensuring reliable integration into complex industrial control environments.

Features

• 16 individually isolated input channels for enhanced signal protection.
• Integrated Sequence of Events (SOE) functionality for high-resolution event logging.
• Compatible with 125V DC nominal input voltages.
• Designed for high-density I/O requirements within the ControlLogix chassis.
• Low power dissipation of 5.5 Watts at 60 degC.

Technical Specifications

Installation Guidelines

• Ensure the ControlLogix chassis is powered down before inserting or removing the module.
• Use appropriate shielded cabling to minimize EMI interference in high-voltage DC environments.
• Verify that the module is fully seated in the chassis slot and secured with the top and bottom latches.
• Adhere to standard ESD protection practices when handling the module to prevent damage to internal circuitry.
• Proper grounding of the chassis backplane is essential for maintaining signal integrity and safety.

FAQ

What is the primary function of the SOE feature on this module?
The Sequence of Events (SOE) capability allows the module to record the precise timing of input state changes, which is critical for fault analysis and process monitoring in time-sensitive applications.

Can this module be used in a standard ControlLogix chassis?
Yes, the 1756-IH16ISOE is designed to fit standard 1756 ControlLogix chassis and requires a compatible Removable Terminal Block (RTB) for field wiring.
