The DRA1-CX240D5-B is a DIN rail mount solid state relay (SSR) assembly designed for industrial switching applications. This single-channel device features a 5A maximum load current rating with 1-60VDC operating voltage range and 3-10VDC control voltage input, delivering reliable DC switching performance. The SSR incorporates a maximum on-state resistance of 0.1 Ohm and on-state voltage drop of 0.5VDC at rated current, ensuring efficient power transfer with minimal heat generation. With a maximum turn-on time of 1 millisecond and turn-off time of 300 microseconds, the relay provides fast switching response suitable for automation and control systems. The assembly includes cage-style screw terminals for secure connections, fits standard 35mm DIN rail, and features an LED status indicator for operational visibility. Common applications include motor control, pump switching, heating element control, and general industrial automation where compact, reliable DC switching is required.
