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 15-30 VDC. On the output side, voltages of 24-280 VAC up to 2 A can be switched single-phase. The switching behavior is instantaneous, takes place using SCRs (thyristors) and corresponds to a normally open contact. A suitable socket would be SSLZRA1 or SSLZVA1.
