Electrical Relay ALLNET ALL4020 Black White

The ALLNET ALL4020 electrical relay is a compact, DIN-rail mountable switching module compatible with ALL3000, 3418v2, 3500, 400x, 4500 and 5000 systems. It comes in black or white, weighs 114 g and is designed for reliable isolated switching in control and automation installations.

Advantages

This relay provides an isolated reed contact with a switched-circuit rating of 100 mA, reducing interference between control and load circuits. Its 27 mm width fits standard DIN-rail installations while the lightweight, compact housing simplifies mounting and integration into existing control panels.

Suitable for

• Signal-level switching in building automation and control systems
• Integration into DIN-rail enclosures and distribution boards
• Low-current isolation between sensors, controllers and monitoring equipment

How to use

Mount the ALL4020 on a standard DIN-rail and wire control and load circuits according to the system documentation. Ensure that the switched circuit does not exceed the 100 mA rating. Verify compatibility with the host device (ALL3000/3418v2/3500/400x/4500/5000) before installation and follow local electrical safety regulations when connecting the relay.

Recommendations

Use the relay for low-current signal isolation and switching; avoid using it for mains power switching or loads that exceed the specified 100 mA. Regularly inspect connections for corrosion or loosening in environments with vibration or moisture.
