Crydom D5D07 Solid State Relay

The Crydom D5D07 is a robust, panel-mount solid-state relay designed for DC load switching applications in industrial automation, process control, and power management systems. This relay features a compact hockey-puck design with optically isolated input and output, ensuring reliable performance in harsh environments. Key benefits include zero-voltage switching to minimize electrical noise, high surge current capability for handling inductive loads, and a long operational life compared to mechanical relays, reducing maintenance costs. It supports a wide output voltage range up to 500V DC and a continuous current of 7A, making it suitable for controlling motors, heaters, solenoids, and other DC-powered devices. Advantages over similar products include superior thermal management with an integrated heat sink mounting option, high dielectric strength for safety, and compatibility with PLCs and microcontrollers via low-voltage DC control. Drawbacks may include the need for external heat sinking in high-current applications to prevent overheating, and it's not suitable for AC loads. Based on attached images, the unit appears new or unused, in original packaging with mounting screws, showing no signs of wear or damage. Faceplate details confirm model D5D07, input 3.5-32V, output 500V 7A, with markings 'L57 9026' possibly indicating batch or serial. No parent/child assets are visible. Estimated market price for a new unit is $40-60 USD based on recent online listings for comparable Crydom SSRs; this is an estimate from sources like eBay and industrial suppliers.
