Relay provides solid-state switching.
July 31, 2002 - Model 34.81 relay is available in 2 versions: Model 34.81.9024 is designed for switching up to 2 A at 24 Vdc, while Model 34.81.7048 can switch up to 100 mA at 48 Vdc. Each can be specified for 24 or 60 Vdc control input. With silent operation, 34-series relay has 28 x 5 mm footprint and measures only 15 mm high. It mounts on PCB via solder pins. Dielectric strength between input and output is rated at 2.5 kV.

Relay Maker Finder Breaks Into Solid-State Market
European relay and timer manufacturer Finder has entered the solid-state relay market for the first time with an ultra-slim version of the company's 34-series electromechanical PCB-mounting part.
Measuring just 5mm wide - not much thicker than a floppy disk - the new relay has a wide range of switching applications where ultra-long working life, high-speed, reliability and compactness are paramount. Because of the popularity of the existing 34-series relays in PLC, electronic control-and interface applications, it is expected that the new solid-state alternative will establish itself rapidly in these areas.
Designated the 34.81, the new relay is initially available in two models. One has the part-number suffix 9024 and is designed for switching up to 2A at 24V DC. Its partner - suffixed 7048 - can switch up to 100mA but at 48V DC. Each can be specified for 24V or 60V DC control input.
Featuring silent operation, the 34-series solid-state relay has a footprint of 28mm by 5mm and measures 15mm high. It mounts on the PCB via its solder pins. Dielectric strength between the input and output of this relay is 2.5kV.
Located in Stone, Staffordshire, Finder is the UK subsidiary of Italian company Finder SpA who manufacture a wide range of relays from small PCB models through to heavy duty, high current types.
Background
Conventional electromechanical relays often have a life of 100,000 operations. They involve moving parts and contacts that wear at a rate proportional to their loading. In contrast, solid-state relays have an almost infinite operational life, and hence excel in applications involving frequent switch cycling.
