Elektrisk relæ ALLNET ALL4024 sort blå grå orange

The ALLNET ALL4024 electrical relay is a single-phase DIN-rail volt meter and relay module designed for AC systems with 220–240 V input. It detects presence or absence of mains power and provides isolated switching via an internal relay. The unit fits a 27 mm DIN-rail enclosure and is available in Black, Blue, Grey, and Orange. It includes a 1 m connection cable and is compatible with ALL3000, 3418v2, 3500, 400x, 4500 and 5000 devices.

Advantages

The relay combines voltage detection and isolated switching in one compact DIN-rail module, simplifying installation in control cabinets. Its 27 mm width saves rail space while the built-in relay ensures electrical isolation between measurement and switched circuits. Compatibility with several ALLNET models and the included 1 m cable reduce the need for additional accessories.

Suitable for

• Detecting mains presence in single-phase AC installations (220–240 V)
• Integration into DIN-rail control cabinets and distribution boards
• Remote signaling or control when paired with compatible ALLNET devices

Key specifications

• Model: ALLNET ALL4024
• Function: Volt meter with isolated relay
• Input voltage: AC 220–240 V (single-phase)
• Mounting: DIN rail, 27 mm width
• Included cable: 1 m
• Compatibility: ALL3000 / 3418v2 / 3500 / 400x / 4500 / 5000

How to use

Mount the ALL4024 on a standard 35 mm DIN rail in the control cabinet and connect the supply conductors according to the device wiring diagram. Use the included 1 m cable to link the relay output to the target device or control input. The unit will detect mains voltage automatically and actuate its isolated relay when configured voltages are present. Observe wiring polarity and safety standards during installation.

Recommendations

Install and wire the relay only with power disconnected and by a qualified electrician. Ensure the relay’s voltage range (220–240 V AC) matches the installation supply. For reliable operation, keep connections tight and avoid exposing the module to excessive moisture or heat.
