This compact device facilitates reliable electrical isolation and efficient signal transmission, ensuring that your electrical installations maintain operational stability over extended periods. Designed to handle a supply voltage range of 220-240V AC/DC, it serves as a robust link between control electronics and high-power field devices.

Advantages

This interface relay offers exceptional reliability due to its high-quality construction and optimized power consumption of 0.9 VA or 0.86 W. Its compact design allows for space-saving installation in crowded control cabinets, while the universal AC/DC voltage compatibility simplifies inventory management and system design. By providing effective electrical isolation, it protects sensitive control circuits from voltage spikes and interference, contributing to the overall longevity and safety of the automation system.

Suitable for

• Industrial automation and control systems
• Signal transmission between controllers and actuators
• Electrical isolation in control panels
• Building automation and HVAC systems

When it may not be suitable

This relay is not intended for switching high-current loads directly, as it is designed primarily for signal-level interface tasks. It should not be used in environments exceeding its specified voltage or temperature ratings, nor in applications requiring high-frequency switching beyond the mechanical capabilities of the relay contacts.

Key specifications

• Supply voltage: 220-240V AC/DC
• Power consumption: 0.9 VA / 0.86 W
• Function: Interface signal switching
• Design: Compact modular housing

How to use

The relay is designed for standard DIN-rail mounting within a control cabinet. Ensure that the supply voltage matches the specified 220-240V AC/DC range before making connections. Wiring should be performed by qualified personnel according to the provided terminal diagram, ensuring that all connections are secure and that the load connected to the output contacts does not exceed the rated capacity of the device.

What to consider before purchase

• Verify that your control system voltage matches the 220-240V AC/DC requirement.
• Ensure the physical space in your cabinet is sufficient for the relay dimensions.
• Confirm the load requirements of your application to ensure they align with the relay's switching capacity.

Usage recommendations

Regularly inspect the terminal connections for tightness and ensure the relay is free from dust or moisture accumulation to maintain optimal performance and prevent contact degradation.
