USB Module Monitors Four AC Lines

The Model JSB-375 module monitors four ac lines and includes four 15A SPST relays. Monitor inputs sense ac voltage and the current state of each input can be read from the USB port. The SPST relays outputs provide host control between a common line and normally open connection point. Models support two or four monitors and relays. Users communicate with the module from any programming or test language that supports USB communications. Single unit price for the Model JSB370 starts at $95. J-WORKS INC., Granada Hills, CA.
