Description

The Siemens 6AV3672-1CA11, also known as the CPI 1, is a specialized control panel interface module designed for integration with Siemens SIMATIC OP27 and TP27-6 operator panels. This daughterboard module serves as a critical expansion component, providing 16 configurable digital inputs and outputs directly at the HMI level. By facilitating the connection of physical pushbuttons, indicator lamps, and switches, it allows for localized control and monitoring, reducing the communication load on the primary fieldbus and ensuring responsive operator interaction in demanding industrial environments.

Features

• Designed specifically for seamless integration with Siemens OP27 and TP27-6 HMI hardware.
• Provides 16 discrete digital I/O channels for local panel control.
• Features optocoupler isolation to protect internal HMI circuitry from electrical noise and voltage transients.
• Operates on a standard 24 VDC power supply, consistent with industrial control panel requirements.
• Reduces latency for critical operator-initiated machine commands.

Applications

This interface module is typically utilized in manufacturing and process automation sectors where physical operator feedback is required. Common applications include automotive assembly line controls, automated material handling systems, and food processing machinery where the HMI serves as the primary interface for localized diagnostic and operational tasks.

Technical Specifications

Installation Guidelines

• Ensure the HMI unit is fully powered down and disconnected from the main power source before attempting to install or remove the interface module.
• Handle the module using proper ESD (Electrostatic Discharge) precautions to prevent damage to sensitive internal components.
• Verify that the module is correctly seated on the host panel's internal bus connector to ensure stable signal transmission.
• Ensure that all field wiring connected to the 16 I/O points is properly routed and secured to prevent mechanical stress on the board connectors.
• Maintain adequate ventilation within the control panel enclosure to ensure the module stays within its specified operating temperature range.

FAQ

Is this module compatible with other Siemens HMI series?

No, the 6AV3672-1CA11 is engineered specifically for the OP27 and TP27-6 series. It is not designed for use with newer generation SIMATIC HMI panels.

Does the module require external configuration?

The module integrates into the HMI runtime environment. Ensure your HMI project configuration is updated to recognize the additional I/O points provided by the CPI 1 board.
