## Description

25A solid state relay for fast and silent control of AC loads, ideal in automation and electrical panels. Non-contact, spark-free switching, with TRIAC and zero crossing to reduce start-up shocks, has optical isolation between 3-32VDC input and 24-380VAC output, LED status and screw mounting.
Solid state relay (SSR) of 25A power, differs from the classic relay by switching without contact, which makes it possible to actuate it without sparks and noise, with a fast switching speed.
Benefits include TRIAC output, electromagnetic isolation, fast actuation, moisture resistance, zero closing current and optical isolation between the input and output circuits.
Important: Check the temperature of the relay. With loads greater than 4A, a radiator is recommended.
