Finder 56.34.9.110.4000 industrial power relay with a 110 V DC coil, four changeover contacts, 12 A rated contact current, silver tin oxide contacts and plug-in mounting for industrial automation, machinery control and electrical switching applications.
Why Choose the Finder 56.34.9.110.4000 Industrial Power Relay?
The Finder 56.34.9.110.4000 is a 12 A industrial electromechanical power relay featuring a 110 V DC operating coil, four changeover contacts and silver tin oxide (AgSnO2) contact material. Part of the Finder 56 Series, this plug-in relay is designed for industrial automation, electrical control panels, machinery and multi-circuit switching applications.
Its 4 CO / 4PDT contact configuration enables four separate changeover circuits to be operated simultaneously by a single electromagnetic coil. With a 12 A rated contact current, 250 V AC rated contact voltage and 3,000 VA AC1 switching capacity, the relay offers flexible switching for appropriately rated industrial loads.
The Finder 56.34.9.110.4000 uses AgSnO2 contacts, which offer useful resistance to contact welding and erosion under certain demanding switching conditions. Its standard configuration, without an integrated test button or indicator, provides a straightforward relay solution for use with compatible Finder 96 Series sockets.

Technical note: The 110 V DC coil data relates specifically to the four-pole Finder 56.34 configuration. The 4000 suffix identifies AgSnO2 contacts with standard changeover circuitry and no optional test button or indicator. Contact ratings and endurance values are based on Finder's published 56 Series specifications and should be applied according to the manufacturer's load conditions and derating guidance.
Silver Tin Oxide Contacts for Demanding Industrial Switching
The Finder 56.34.9.110.4000 features silver tin oxide (AgSnO2) contacts, offering an alternative to the standard silver-nickel contacts available in other Finder 56 Series variants.
AgSnO2 contacts are commonly selected for their resistance to contact welding and electrical erosion under certain demanding switching conditions. These characteristics can be useful in applications involving elevated inrush currents, provided the electrical load remains within the relay's specified ratings.
The relay provides a 12 A rated contact current and 3,000 VA AC1 resistive switching capacity. Inductive, capacitive and motor loads may impose significantly different switching stresses, so the applicable AC15, motor or DC load ratings should be used when assessing suitability.
Four Changeover Contacts for Flexible Control
The Finder 56.34.9.110.4000 contains four independent changeover contact sets operated by a common 110 V DC electromagnetic coil.
Each pole provides a common terminal, a normally closed contact and a normally open contact. When the coil is energised, all four contact sets transfer to their operated positions. Removing the coil voltage allows the relay to return to its normal state.
This 4PDT arrangement is useful for applications requiring multiple switching or signalling functions from a single control signal, including auxiliary machinery controls, electrical interlocking, alarm systems and industrial process equipment.
Convenient Plug-In Installation and Maintenance
The Finder 56.34.9.110.4000 features Faston 187 plug-in terminals designed for compatible Finder 96 Series relay sockets. Its socket-mounted construction allows installation into industrial electrical assemblies without permanently soldering the relay into the equipment.
Plug-in mounting also supports convenient relay replacement during maintenance. Technicians can remove the relay from its socket without disconnecting the permanent wiring, provided the circuit has first been isolated and made safe.
The 4000 configuration is the standard version without a test button or mechanical indicator. This makes it suitable for installations where those optional features are unnecessary or where relay operation is monitored through the surrounding control system.
Typical Applications
- Industrial automation and electrical control panels.
- Machinery auxiliary switching circuits.
- Multi-circuit electrical switching systems.
- Industrial process control equipment.
- Electrical interlocking and sequencing circuits.
- Motor control auxiliary circuits within the specified ratings.
- Industrial signalling and alarm systems.
