描述

SILD845160 is an AC semiconductor contactor designed for single-phase AC load control with integrated diagnostic functionality and compact DIN rail mounting. The device features zero-cross switching technology with an output voltage range of 70–280VAC and a rated output current of 32A, utilizing 50A back-to-back thyristors with TMS2 technology providing an I²t value exceeding 1500A²s. The control input accepts 3–32VDC with a current draw below 10mA across the entire range, and includes a diagnostic system that monitors both SSR status and load condition via a yellow LED indicator, with status output capability that can be chained without requiring external power. The device is housed in an IP20 enclosure, operates across an ambient temperature range of -40°C to +80°C, and is designed in conformity with EN60947-4-3 and EN60950 standards, making it suitable for industrial automation, heating control, and resistive load switching applications where reliable, maintenance-free operation is required.
