Suitable for

• Small-scale industrial automation systems
• Lighting control and building management
• Conveyor belt control and monitoring
• HVAC system management
• Pump and motor control applications

When it may not be suitable

This device is not intended for complex, high-speed motion control or large-scale industrial processes that require advanced PLC capabilities. It may also be unsuitable for environments where the input voltage exceeds the specified 240V AC range or where the number of required I/O points exceeds the 12 inputs and 8 outputs provided.

Key specifications

• Supply voltage: 240V AC
• Digital inputs: 12
• Relay outputs: 8
• Contact current capacity: 8 A
• Integrated features: LCD display and Real-Time Clock (RTC)
• Weight: 380 g

How to use

Installation should be performed by qualified personnel in accordance with local electrical regulations. The relay is typically mounted on a standard DIN rail within an electrical enclosure. Once mounted, connect the power supply to the designated terminals and wire the sensors to the digital inputs and the actuators to the relay outputs. Configuration is performed using the front-facing LCD panel and buttons, or via compatible programming software to define the logic sequences required for your specific application.

What to consider before purchase

• Verify that your power supply matches the 240V AC requirement
• Ensure the number of inputs and outputs meets your project needs
• Check the physical dimensions for installation space compatibility
• Confirm that the logic requirements fall within the capabilities of the Zelio Logic series

Usage recommendations

Always ensure that the device is installed in a clean, dry environment protected from extreme temperatures and vibrations to maintain optimal performance and longevity.
