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 16-30 VDC. On the output side, voltages of 1-48 VDC up to 0.1 A can be switched single-pole. The switching behavior is DC switching, is carried out by transistors and corresponds to a normally open contact. A suitable socket would be SSLZRA1 or SSLZVA1.
