COTO TECHNOLOGY CT474 Solid-State Relay

The CT474 and CS474 are reliable solid-state relays designed for security, measurement, and instrumentation applications. Capable of switching current up to 90mA and handling load voltages up to 400V, these relays feature low on-resistance of 50Q maximum and are suitable for high-voltage, low-current switching. They incorporate built-in LED indicators, excellent electrical isolation, and robust construction for industrial environments. Their compact size, combined with high breakdown voltage and fast switching times, makes them ideal for automation and control systems requiring reliable performance under varied operational conditions.
