Carlo Gavazzi RM1A23D75S18 Solid State Relay

The RM1A23D75 is a 1‑pole panel‑mount solid‑state relay from Carlo Gavazzi that uses zero‑cross switching to drive AC loads, offering quiet, maintenance‑free operation for on/off control in automation systems. It supports an operating load voltage of 24 to 265 VAC (650 V peak) and provides a continuous load current rating of 75 A (AC‑51) with a 20 A rating for inductive loads (AC‑53a), making it suitable for resistive and mild inductive applications such as heating elements, pumps, and motor controls. The input control is DC, 3 to 32 V, allowing direct interfacing with 24 V logic signals, and the device includes built‑in overvoltage protection to guard against transients on the control line. Termination is via screw with captive clamps, enabling secure connections in compact panel installations. As part of Carlo Gavazzi’s RM1A family, this relay is designed for single‑pole, panel‑mount applications requiring reliable solid‑state switching and is supported by datasheets with E‑Numbers 4134738 (NO) and 4029270 (SE) for traceability.
