Carlo Gavazzi RM1A23D50S18 Solid State Relay

Carlo Gavazzi RM1A23D50S18 Solid State Relay is a 1‑pole, panel‑mount SSR designed to switch AC loads from a DC control signal. It uses zero‑cross switching to minimize arcing and EMI, and its output is rated for up to 50 A at 24–265 VAC (650 V peak). The input control accepts 3–32 V DC, enabling direct interfacing with PLCs or logic circuits, while the power connection uses a screw with captive clamp for reliable wiring. Built‑in overvoltage protection guards the load against transient spikes, and the device measures about 44.8 × 58.2 × 28.8 mm, making it compact enough for standard control panels. An optional heatsink is available to help manage heat when operating near the current limit. Ideal for resistive AC loads such as heating elements and other high‑current applications, this RM1A series relay provides long life and quiet operation by eliminating mechanical contacts and wear, with a single‑pole, 1‑phase configuration that suits a wide range of industrial control tasks.
