IDEC Corporation RSCDN20A Solid State Relay

The RSCDN-20A is a compact solid-state relay with a built-in anodized aluminum heat sink and UL94V-0 polycarbonate housing. Designed for reliable industrial switching, it features LED indicators, finger-safe terminals, and zero-voltage switching. The relay includes back-to-back SCR output and built-in transient voltage suppression (TVS). It offers high electrical isolation with 4200 VRMS, a peak voltage of 1100V non-repetitive, and a maximum off-state leakage current of 120 μA at 25°C. Rated for IP20 protection, it supports up to 20A current at controlled voltages from 48-600VAC, making it ideal for automation and industrial control systems.
