Reliable DC-Controlled Power Switching for Industrial Automation
Electromagnetic power relays such as the Finder 66.22.9.024.4000 allow electrical loads to be controlled through a separate DC control circuit. When the 24 V DC coil is energised, the relay's electromagnetic mechanism transfers both changeover contacts from their normally closed positions to their normally open positions. When the coil is de-energised, the contacts return to their normal state.
The Finder Series 66 is designed for applications requiring substantial contact current capacity, electrical isolation and dependable switching performance. The two changeover contacts of the 66.22.9.024.4000 provide additional flexibility compared with normally open-only relays, enabling changeover control, load selection and switching between alternative electrical paths.
Its PCB-mounted format supports integration into industrial power control boards, electrical equipment and OEM automation assemblies. The 24 V DC coil is suitable for appropriately rated industrial control outputs, while the high-current contact system supports power switching duties within the manufacturer's specified operating limits. Correct PCB conductor sizing, protective devices, thermal management and load-specific contact derating are important for reliable operation.

Frequently Asked Questions
What is the Finder 66.22.9.024.4000 used for?
The Finder 66.22.9.024.4000 is an electromagnetic power relay used to switch electrical loads in industrial automation, machinery control, power management and electrical equipment. Its two changeover contacts allow two independent circuits to be switched between normally open and normally closed connections.
What is the coil voltage of the Finder 66.22.9.024.4000?
The relay features a 24 V DC nominal operating coil, making it suitable for industrial control systems and electronic equipment using a compatible DC power supply.
What is the contact current rating of this relay?
The Finder 66.22.9.024.4000 features a 30 A nominal normally open contact rating and a 10 A nominal normally closed contact rating. The permissible switching current depends on the load type, switching voltage and operating conditions.
What does DPDT mean on the Finder 66.22.9.024.4000?
DPDT (Double Pole Double Throw) means the relay contains two independent changeover contact sets. Each set has a common terminal, a normally open terminal and a normally closed terminal, allowing the relay to transfer two circuits between alternative connections.
What is the difference between the Finder 66.22.9.024.4000 and 66.22.9.024.1600?
The 66.22.9.024.4000 uses a two-changeover-contact arrangement (2 CO / DPDT), while the 66.22.9.024.1600 belongs to the same 24 V DC Series 66 relay family but has a different contact and connection variant. The complete contact diagram and terminal arrangement should be checked before substituting one version for another.
Can this relay be controlled by a PLC?
Yes. The Finder 66.22.9.024.4000 can be controlled by a 24 V DC PLC output or another compatible industrial control circuit, provided the output has sufficient current capacity for the relay coil. Appropriate coil suppression or an interposing driver may be required.
How is the Finder 66.22.9.024.4000 installed?
The relay is designed for printed circuit board (PCB) mounting using solder terminals. The PCB must be designed to accommodate the relay's electrical connections, current-carrying requirements and insulation clearances.
Can the Finder 66.22.9.024.4000 switch both AC and DC loads?
The relay can be used for AC and appropriately rated DC switching applications. Its nominal AC switching voltage is 250 V AC, while DC switching capability depends on the applied voltage, load characteristics and the manufacturer's DC breaking-capacity limits.
What is the advantage of changeover contacts?
