Integrated AC Power Supply for Global Compatibility

The Siemens 6ES7214-2AS23-0XB0 features a built-in AC power supply accepting 85-264V AC. This wide input range covers all major power grids worldwide without manual switching. Users can connect the unit directly to standard mains supplies. The integrated power supply reduces external component count and installation complexity.

Balanced I/O Configuration for Diverse Applications

This CPU includes 14 digital inputs and 10 relay outputs for versatile control tasks. The I/O mix suits applications requiring moderate sensing and actuation capacity. The 24V DC inputs connect to standard industrial sensors and switches. The relay outputs switch 2A loads for actuators and contactors directly.

Relay Outputs for Load Isolation

Ten relay outputs provide complete electrical isolation between the PLC and field circuits. These outputs handle both AC and DC loads at 2A per contact. Users can switch inductive loads without additional interface relays. The relays ensure reliable operation in electrically noisy environments.

Robust Construction for Industrial Environments

The unit measures 196 x 80 x 62 mm and weighs 0.63 kg for stable installation. The IP20-rated housing protects internal components from dust and accidental contact. The AC power supply includes built-in filtering for noisy mains conditions. Users can deploy the unit in harsh factory environments with confidence.

Expandable Architecture with Five Module Support

The CPU 214 accommodates up to 5 expansion modules for system growth. This expandability provides flexibility for changing application requirements. Users can add digital, analog, or communication modules as needed. The expansion bus connects via the side-mounted interface for simple installation.

Energy-Efficient Operation with SuperCap Backup

The unit consumes only 12W for low energy costs and heat generation. A SuperCap provides 100 hours of real-time clock and data retention backup. This energy storage preserves critical parameters during power interruptions. Users benefit from reduced energy consumption and minimal heat dissipation.
