56.34.9.048.2040 Finder Miniature power relay 4 pole 12A DC 48V

Q: What is the Finder 56.34.9.048.2040 used for?

The Finder 56.34.9.048.2040 is a miniature electromechanical power relay used to switch and control electrical circuits in industrial automation, control panels, machinery and electrical equipment. Its four changeover contacts allow multiple circuits to be switched using a single control signal.

Q: What coil voltage does this relay require?

The relay uses a 48 V DC coil. The Finder 56 Series four-pole DC coil specification provides an operating voltage range of approximately 40.8–52.8 V DC for the 48 V version.

Q: What is the contact rating of the Finder 56.34.9.048.2040?

The relay has four changeover contacts rated at 12 A, with a rated contact voltage of 250 V AC and a maximum switching voltage of 400 V AC. The permitted switching load depends on the electrical load category and operating conditions.

Q: What does the 4PDT contact configuration mean?

4PDT (four-pole double-throw) means the relay contains four independent changeover contacts. Each contact can switch between normally closed and normally open connections when the relay coil is energised, allowing four separate circuits to be controlled simultaneously.

Q: How is the Finder 56.34.9.048.2040 installed?

The relay uses a plug-in mounting arrangement and can be installed using a compatible Finder 96 Series relay socket. This makes installation and replacement convenient within electrical control panels and industrial automation cabinets.

Reliable Electrical Switching for Industrial Automation

Electromechanical relays such as the Finder 56.34.9.048.2040 provide electrical isolation between control and switching circuits. When the 48 V DC coil is energised, the relay's four changeover contacts transfer simultaneously, allowing connected electrical circuits to be switched through a single control signal. This makes the relay particularly useful for PLC-controlled machinery, industrial control circuits and electrical automation systems.

The Finder 56 Series is designed for dependable electrical switching and convenient integration into industrial installations. Its plug-in construction supports straightforward replacement without extensive rewiring when used with a suitable socket. The four-pole contact arrangement also enables multiple control functions to be operated together, reducing the need for separate individual relays in suitable applications.
