Solid-State Relay Zelio Relay SSL. Prefabricated solid-state relay in a plug-in base for direct use, with a width of 6.2 mm for mounting on a DIN rail. The input for the control voltage is 16-30 VDC. The switching output is 1-48 VDC, 0.1 A, with DC switching. It features a single-pole transistor output that corresponds to a normally open contact. The socket includes an LED indicator, reverse polarity protection, and a lever for locking or easy removal. It uses screw terminal connection technology, and the connection of comb busbars for potential bridging is available.
