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

When it may not be suitable

This device is not intended for high-power industrial applications that require switching currents exceeding 5A per output. It is also not suitable for complex, large-scale automation projects that demand high-speed processing or extensive communication protocols beyond the capabilities of the Zelio Logic series.

Key specifications

• Supply voltage: 24V DC
• Digital inputs: 16
• Relay outputs: 10
• Contact current capacity: 5A
• Integrated display: LCD
• Weight: 400g

How to use

The SR3B261BD is installed on a standard DIN rail within a control cabinet. Wiring is performed by connecting sensors to the digital inputs and actuators to the relay outputs according to the system schematic. Programming is achieved using the Zelio Soft software or via the front-panel interface. Once configured, the relay executes the programmed logic to control the connected equipment based on the input signals received.

What to consider before purchase

• Ensure the 24V DC power supply matches your existing control infrastructure.
• Verify that the 5A output capacity is sufficient for your specific connected loads.
• Check if the number of inputs and outputs meets the requirements of your automation project.
• Confirm that the installation environment is within the specified operating temperature range.

Usage recommendations

Always ensure that the power supply is disconnected before performing any wiring or maintenance tasks. Use appropriate surge protection for inductive loads to extend the lifespan of the relay contacts.
