SC1010 solid state relay controler card photo non-contractual description SC1010 is a solid state relay controller card. it is intended to be used in applications where high reliability is needed. this card is configurable to trigger scr?s with 20khz pulse trains synchronised with mains voltage or in permanent mode. it can be configured to start at zero crossing or random phase. control signal can be logic level refereed to card reference (high input impedance) or floating optocoupled input (low input impedance). built in power supply is feed directly from the mains either 230 v or 400 v, 50 hz. dimensions dimensions and component situation preliminary information
