Relay Relies On USB Control

The Model JSB212 2A/60W SPDT form C relay is controllable via its integrated USB port to provide host control between a common line and normally open and closed connection points. Three indicator options are available. Option 1 uses an LED for each relay that is on when the relay is closed while Option 2 has connectors so external LEDs can be wired in. One pin is ground, the other is switched between USB supplied 5V or nothing. Option 3 allows users to supply a voltage to the LED output connector. There is a four- and eight-relay version with either a screw-type terminal block or KK series header. Single unit price for the Model JSB212 starts at $125. J-WORKS INC., Granada Hills, CA.
