Solid solid state relays - are designed for contactless switching of heating elements,
lamps, welding machines and other devices with a resistive load type and operating voltage from 24 to 480V
VAC or 5 VDC ... 60B. For switching inductive loads must have 5 - 8
fold supply current.
Due to non-contact solid state relay switch has the following advantages over electromechanical:
   - No sparks and arcing during switching;
   - Significantly lower level of electromagnetic interference;
   - Has a significantly longer service life and requires no maintenance work during operation;
   - High performance;
   - Small size and good heat dissipation.
