AutomationDirect EA-AC Touch Screen Power Adapter

Product Dimensions：

The AutomationDirect EA-AC is an optional AC Power Adapter Module designed specifically for the C-more EA7 Series Human-Machine Interfaces (HMIs). It allows standard 24 V DC-powered touch panels to be operated directly from a wider range of line-level AC power sources.

Product Detailed Description

By default, standard C-more touch panels require a 24 V DC power supply. The EA-AC module attaches directly to the back of compatible EA7 series panels, converting line-level AC voltage (100–240 V AC) down to the regulated 24 V DC power needed to operate the display, internal logic, and optional expansion modules.

Technical Specifications

Key Product Advantages

• Eliminates External DC Power Supplies: Allows direct connection to standard AC mains in cabinets where a dedicated 24 V DC power supply is not already available.
• Direct Panel Mounting: Fits snugly onto the back of compatible EA7 panels, saving DIN rail space inside the electrical panel.
• Universal AC Input: Accepts a wide range of input voltages (100–240 V AC) and frequencies (50/60 Hz), making it suitable for international deployment.
• Seamless Compatibility: Integrates cleanly into the back of the EA7 chassis without requiring additional power jumper wires or mounting brackets.

Important Considerations & Warnings

• Series Compatibility: The EA-AC is designed specifically for EA7 Series C-more panels. It is not compatible with EA9 series panels (which use the EA-AC-2 power adapter) or EA1/EA3 micro series.
• Temperature Derating: When powering large 15-inch panels (such as the EA7-T15C), ambient operating temperature limits may be restricted to 40°C max due to thermal dissipation considerations.
• Power Capacity: The adapter provides up to 1.5 A at 24 V DC. Ensure that the total current draw of the panel plus all attached expansion modules (e.g., audio modules or option cards) does not exceed this capacity.
• Wiring Practice: Always verify that line (L), neutral (N), and protective earth (PE) are correctly terminated to the terminal block before energizing to prevent equipment damage or electrical hazards.

Product Applications

• Standalone Control Enclosures: Used in small machine panels where line-voltage AC is the only power source present.
• Retrofit Projects: Replacing older AC-powered HMIs without needing to add a separate 24 V DC power supply to the cabinet enclosure.
• OEM Machinery: Simplifying cabinet assembly by powering both the HMI and high-voltage line devices directly from the incoming AC mains.
