When it may not be suitable

This relay is not intended for complex, high-speed motion control or large-scale industrial processes that require extensive I/O capacity or advanced communication protocols. It is also not suitable for applications requiring high-voltage AC switching directly through the relay outputs.

Key specifications

• Supply voltage: 24V DC
• Number of inputs: 6
• Number of outputs: 4
• Contact current capacity: 8 A
• Weight: 220 g
• Design: Compact modular form factor

How to use

The device is typically mounted on a standard DIN rail within an electrical enclosure. Wiring should be performed according to the terminal diagram provided in the technical documentation, ensuring that the 24V DC power supply is correctly connected to the input terminals. Programming is achieved through the compatible Zelio Soft software, allowing users to define logic sequences that govern the interaction between the inputs and outputs. Once programmed, the relay operates autonomously to execute the defined control logic.

What to consider before purchase

• Verify that your control system operates on a 24V DC power supply.
• Ensure the 6-input and 4-output configuration meets your project requirements.
• Check that the 8 A contact current capacity is sufficient for your connected loads.
• Confirm that you have the necessary software and programming cables for configuration.

Usage recommendations

Always ensure that the power supply is disconnected before performing any wiring or maintenance tasks. Use appropriate circuit protection devices to safeguard the relay outputs from overcurrent conditions.
