Why Choose the Finder 55.34.8.024.2001 Industrial Relay?
The Finder 55.34.8.024.2001 is a 24 V AC industrial electromagnetic relay from the Finder Series 55 miniature general-purpose relay range. Designed for industrial control and automation applications, the 55.34 relay configuration provides four independent changeover contacts, allowing multiple electrical circuits to be controlled using a single relay coil.
With a four-pole double-throw (4PDT / 4 CO) contact arrangement, this relay offers normally open and normally closed switching functions across four separate contact sets. The Finder 55.34 family is rated at 7 A per contact at 250 V AC for resistive loads, making it suitable for auxiliary control, electrical interlocking, signalling and equipment switching.
The 24 V AC, 50/60 Hz coil supports operation from compatible industrial AC control supplies, while the silver cadmium oxide (AgCdO) contact material identifies a contact option intended for electrical switching applications. The 55.34 design uses plug-in terminals for installation with a suitable relay socket, supporting accessible wiring and convenient maintenance.

Flexible Four-Pole Switching for Industrial Automation
The Finder 55.34.8.024.2001 uses an electromagnetic coil to operate four changeover contact sets together. When the specified 24 V AC supply energises the coil, the contacts transfer from their normally closed positions to their normally open positions. When the coil is de-energised, the contacts return to their normal states.
This 4PDT switching arrangement is particularly useful where several auxiliary functions must operate from a single control signal. It can support simultaneous equipment control, electrical interlocking, alarm signalling and status indication. Each contact set has a 7 A resistive AC rating; inductive, capacitive and high-inrush loads must be evaluated against the manufacturer's applicable load-specific ratings.
The relay's plug-in format supports installation into a compatible socket, helping simplify maintenance in industrial control panels. Appropriate socket selection, coil protection, conductor sizing and contact protection should be incorporated into the electrical design. The exact construction associated with the 2001 suffix should be verified before specifying any special enclosure or sealing characteristics.
Typical Applications
- Industrial automation and machine control systems.
- Electrical control panels and switchgear assemblies.
- PLC interface and auxiliary control circuits.
- Four-circuit electrical switching applications.
- Machinery interlocking and control logic.
- Industrial process control systems.
- Equipment status indication and alarm signalling.
- Building automation and HVAC controls.
- Motor control auxiliary circuits.
- Industrial pumps, fans and ventilation equipment.
- OEM electrical and automation equipment.
- Replacement of compatible Finder Series 55 relays.

Frequently Asked Questions
What is the Finder 55.34.8.024.2001 used for?
The Finder 55.34.8.024.2001 is a general-purpose industrial electromagnetic relay intended for controlling multiple electrical circuits from one AC control signal. Typical applications include automation systems, machinery controls, electrical interlocking and auxiliary switching.
What coil voltage does the Finder 55.34.8.024.2001 require?
The relay uses a 24 V AC nominal coil designed for 50/60 Hz operation. It should be connected to a suitable AC control supply rather than a DC supply.
How many contacts does the Finder 55.34.8.024.2001 have?
The relay has four independent changeover contact sets, described as 4PDT / 4 CO. Each contact set provides a common terminal, a normally open terminal and a normally closed terminal.
What is the contact rating of the Finder 55.34.8.024.2001?
The Finder 55.34 contact system has a 7 A rated contact current at 250 V AC for resistive loads, equivalent to 1,750 VA per contact set. The permissible load must be checked for the specific switching duty.
How is the Finder 55.34.8.024.2001 mounted?
The Finder 55.34 design uses plug-in terminals for installation in a compatible relay socket. Selected Finder Series 94 sockets support suitable mounting arrangements, but exact compatibility should be checked before ordering.
What contact material does the Finder 55.34.8.024.2001 use?
The 2001 configuration identifies silver cadmium oxide (AgCdO) as the contact material. AgCdO is an alternative to the silver nickel (AgNi) contact material used in standard versions of the Finder Series 55 range.
What is the difference between Finder 55.34.8.024.2001 and 55.34.8.024.0000?
Both part numbers share the 55.34 four-changeover-contact design and 24 V AC coil. The 55.34.8.024.0000 is a standard AgNi contact version, while the 55.34.8.024.2001 specifies AgCdO contacts and a different final construction suffix. The suffix-specific construction should be confirmed using Finder's exact ordering documentation.
Designed for Professional Industrial Control Applications
