Socket in a narrow design of 6.2 mm, comparable to a terminal block, for accommodating a pluggable solid-state relay from the SSL1 series. The socket features connection terminals with spring-loaded technology, the ability to accommodate wiring combs for potential bridging, an LED indicator for the control status, a lever for easier installation or ejection of the solid-state relay, and an internal reverse polarity protection with voltage adjustment for controlling the plugged-in solid-state relay. This socket is suitable for all SSL1-JD/BD solid-state relays with a control voltage of 5 to 24 VDC.
