Carlo Gavazzi RM1A48D100 Solid-State Relay

The RM1A48D100 is Carlo Gavazzi’s 1-pole, panel-mount solid-state relay (SSR) with zero-cross switching designed to reliably switch AC loads in compact control panels. It handles a load voltage range of 42–530 Vac (1200 Vp) and a rated output current of up to 100 A (AC-51), with a 30 A rating for inductive loads (AC-53a), making it suitable for resistive and mildly reactive applications such as heaters, lighting, and other 480 V class equipment. The input control accepts 4–32 Vdc signals, and the device includes built-in overvoltage protection to guard against transients common in industrial environments. Output is SPST-NO (1 Form A), and power connections use a screw with captive clamp for straightforward wiring in panel installations. This RM1A48D100 is part of the RM1 family and is compatible with optional heatsink configurations to manage heat at high current, enabling stable operation in continuous duty or frequent switching scenarios while maintaining EMI-friendly switching due to the zero-cross design.
