Frequently Asked Questions

What base options are available for the Finder 55.34.9.024.0000 relay?

This relay is compatible with multiple Finder base options including 94.74, 94.04, 94.54, 94.P4, 94.84.2, 94.94.3, 94.14, 94.24, and 94.34. These bases provide different mounting and connection options including screw terminals, spring terminals, and various DIN rail configurations to suit different installation requirements.

What is the maximum load this 4-pole relay can switch?

The Finder 55.34.9.024.0000 is rated at 7A per contact, meaning each of the four poles can switch up to 7A. The relay features AgNi (silver-nickel) contact material which provides excellent switching performance for both resistive and inductive loads typical in industrial applications.

What are the dimensions and how much panel space does this relay require?

The relay has a width of 20.7mm and features a compact 14-pin design. With a net mass of just 0.03kg, it provides an excellent power-to-size ratio. The pin length is 5.6mm, making it compatible with standard relay bases and ensuring secure connections.

Can this relay operate in harsh environmental conditions?

Yes, the Finder 55 Series relay is designed for demanding applications with an ambient temperature range of -40°C to +85°C. This wide operating range makes it suitable for outdoor installations, cold storage facilities, and high-temperature industrial processes where standard relays might fail.

How does the 4PDT configuration benefit control circuit design?

The 4PDT (4-pole double throw) configuration provides four separate changeover contacts, allowing complex switching operations from a single relay. This reduces panel space, simplifies wiring, and improves system reliability compared to using multiple smaller relays. Each contact set can handle different circuits simultaneously, making it ideal for applications requiring coordinated switching of multiple loads or signal paths.
