Sensata | Crydom Solid-State Relay, 600V Transient Overvoltage, 4000Vrms Dielectric Strength - DUAL Series - D2440D
Looking for a durable component to switch your high-power industrial loads? Go for this solid-state relay from Sensata | Crydom. It packs two output devices in one, so you can use this powerhouse for multi-circuit management. Thanks to its zero-cross switching function, this unit minimises electrical noise by turning on when the load voltage is close to zero. It delivers an output current of up to 40A, making it your best bet for high-power applications. The relay's thermally conductive epoxy housing can withstand heat and impact, so it stays cool under pressure. This device is commonly used in the transportation industry, as well as in process and packaging plants.
Features & Benefits
• High dielectric strength of 4000Vrms reduces the risk of electrical damage
• Operating voltage range between 24 and 280V AC for use in low-voltage applications
• Low I/O capacitance of 10pF for high-integrity signal transmission
• Low input current of 13mA at 5V DC for energy efficiency
• Operating voltage range between 24 and 280V AC for use in low-voltage applications
• Low I/O capacitance of 10pF for high-integrity signal transmission
• Low input current of 13mA at 5V DC for energy efficiency
How do I maintain this relay?
As this device has no moving parts, there's virtually no risk of mechanical wear, meaning it doesn't need any maintenance.
Approvals
UL E116949; CSA LR81689; VDE 5902 UG; CE; ISO
