Sensata Crydom SSR 1 Series 90A Panel Mount Solid State Relay

The Sensata Crydom SSR 1 Series 90A Panel Mount Solid State Relay is a high-performance switching device designed for robust and reliable operation in industrial control applications. Constructed as a solid-state relay (SSR), it offers significant advantages over traditional electromechanical relays, including silent operation, faster switching speeds, exceptional longevity due to the absence of moving parts, and minimal electrical noise generation.

This model features a panel-mount design with screw terminals, ensuring a secure and straightforward installation into control panels and enclosures. It utilises zero-crossing switching technology, which minimises inrush current and reduces electromagnetic interference (EMI), making it ideal for sensitive electronic environments and for controlling resistive loads like heating elements or incandescent lighting.

With a substantial load current rating of 90 amps and a maximum operating voltage of 280V AC, this SSR is capable of handling high-power AC loads. Its wide control voltage range, from 3 to 32V DC, provides excellent compatibility with various logic-level control signals from PLCs, microcontrollers, or other low-voltage DC sources. The SPST-NO (Single Pole, Single Throw, Normally Open) contact configuration offers simple and effective switching for a single circuit.

Key Specifications:

• Load Rating: 90A at up to 280V AC
• Control Input: 3-32V DC
• Switching: Zero-crossing for low EMI
• Mounting: Panel mount with screw terminals
• Configuration: SPST-NO (normally open)
• Construction: Solid-state for long life and silent operation

This relay is a dependable component for automating and controlling high-current AC circuits in applications such as industrial machinery, process heating, packaging equipment, and lighting control systems.
