• Compact footprint for high-density I/O requirements
• Compatible with standard FLEX I/O terminal bases

Technical Specifications

Installation Guidelines

• Ensure the FLEX I/O terminal base is securely mounted to a standard 35mm DIN rail before installing the module.
• Always disconnect power from the system before inserting or removing the module to prevent electrical damage or unexpected system behavior.
• Verify that the module is fully seated in the terminal base to ensure proper backplane communication.
• Use shielded cabling for input signals to minimize electromagnetic interference (EMI) in high-noise industrial environments.
• Ensure proper grounding of the terminal base assembly to the cabinet chassis to maintain signal integrity.

FAQ

What is the input type for the 1794-IB32?

The 1794-IB32 is a sinking input module, meaning it requires a common positive voltage to be switched to the input terminals to register an ON state.

Does this module require a specific terminal base?

Yes, this module is designed to be used with compatible FLEX I/O terminal bases (e.g., 1794-TB3, 1794-TB3S) that support the 32-point density requirements.

Are the status indicators on the front of the module?

Yes, the module features 32 yellow LED indicators on the front panel, providing visual confirmation of the ON/OFF status for each individual input channel.
