Components: Selectable USB Relay Features Four Optoisolated Inputs

The model JSB-340 provides four 2-A form-C relays and optoisolated inputs that plug into a standard USB in a plug-and-play manner. Inputs provide up to 2500-V isolation and are selectable from 0 to 15 V or 0 to 30 V. Screw-type terminal blocks are included. Users can control the relays and sample the input from any programming or test language that supports USB communications. The unit's optical and relay isolation eliminates surges from affecting host PCs in various test, control, monitor, and measurement applications. Single-unit pricing for the JSB-340 starts at $80, and delivery is from stock.
