Sensata Technologies D2425 Relay

Sensata Technologies Crydom D2425 is a dual‑channel solid‑state relay (SSR) with two SPST‑NO outputs in a single panel‑mount package, designed to switch AC loads from 24 to 280 VAC. Each channel is rated for up to 25 A RMS at 24–280 VAC, with a maximum on‑state voltage drop of about 1.6 V at rated current and a minimum load current of 0.15 A, enabling solid isolation of control signals from high‑power circuits. The DC input control covers multiple variants: D2425 accepts 3–32 VDC, D2425D uses 4–15 VDC, and D2425DE uses 15–32 VDC, giving flexibility for different control logic levels. Off‑state leakage is specified up to 10 mA at rated voltage, and the output supports either zero‑voltage switching for resistive loads or instantaneous turn‑on for inductive loads. The device tolerates a broad ambient range from −40°C to 100°C and offers substantial surge capability (approximately 239–250 A peak per 1/2 cycle, 50/60 Hz) with a minimum dv/dt of 500 V/µs. Construction features include panel‑mount, screw terminals for easy wiring in control panels and industrial equipment, and certifications including CE, CSA, and cURus. This Crydom/ Sensata SSR is well suited for high‑current AC switching tasks such as heating elements, motors, and lighting where fast, reliable solid‑state switching is advantageous.
