The Autonics SRH3-1230 is a solid state relay with a 4–30VDC control voltage, a 30A switching power, a 24–240VAC operating voltage, and a 3-phase configuration. The relay is designed to be compatible with DIN-type mounting. It features overcurrent protection, back EMF protection, preheating and preventive protection, and a wide range of operating temperatures. The relay is suitable for resistive and inductive loads, with a low switching time, and high efficiency and reliability.
