Harmony Relay. Plug-in semiconductor relay as a component for installation in a separate plug-in socket in a slim design of 6.2 mm. Control is carried out in the voltage range 3-12 VDC. On the output side, voltages of 24-280 VAC up to 2 A can be switched single-phase. The switching behavior is zero-voltage switching, is carried out by means of SCR (thyristors) and corresponds to a normally open contact. The semiconductor relay has no displays, which are contained in the separate socket with a protective circuit. A suitable socket would be SSLZRA1 or SSLZVA1.
