Finder Solid-State relé 77.01.9.024.8050, 5 A, 265 V AC, prechod nulou, montáž na PCB

Automation engineers and panel builders use the Finder 77.01.9.024.8050 solid state relay to switch AC loads up to 5 A in industrial control cabinets, HVAC systems, and lighting installations. Its zero-crossing switching principle reduces inrush currents and electromagnetic interference, making it suitable for resistive loads where silent operation and long service life are required.

Key specifications

• Relay type: Solid state relay (SSR)
• Switching principle: Zero-crossing
• Rated output current: 5 A
• Maximum output voltage: 265 V AC
• Control voltage: 24 V DC
• Output voltage range: 24–265 V AC
• Output current range: 0.05–5 A
• Mounting type: PCB mount
• Number of poles: 1 (SPST-NO)
• Isolation voltage (input-output): 4000 V AC
• Operating temperature range: -20 to +70 °C
• Input current at rated voltage: 10 mA
• Maximum surge current (10 ms): 50 A
• Turn-on time: 0.1 ms
• Turn-off time: 0.1 ms
• Dielectric strength (input-output): 4 kV AC

Why choose it

The zero-crossing switching ensures minimal EMI and reduced stress on connected loads, while the solid state design eliminates mechanical wear for millions of operations. With 4 kV isolation and a wide temperature range, it integrates reliably into demanding industrial environments.

Ideal use cases

• Switching resistive loads such as heaters and lamps
• Replacing electromechanical relays in high-cycle applications
• PCB-mounted control circuits requiring silent, fast switching

Good to know

The relay is designed for PCB mounting and has an IP00 protection category, meaning it must be installed in an enclosure. It complies with EN 60947-5-1 and EN 62314 standards.
