JSB340
The JSB-340 USB Small Form Opto Isolator In / Relay (SPDT) Out module provides 4 optically isolated inputs for connection to user devices such as sensors or switches. The inputs sense DC voltage that can be read from the host PC, while providing optical isolation, which eliminates surges present in industrial environments from effecting the host PC. The 2 or 4 SPDT relays outputs provide host control between a common line and normally open and close connection point. It will switch up to 220 Volts. It has a simple to use Windows interface using either a traditional DLL. Sample source is included showing how to use various high level languages to control the device. Screw type terminal blocks are on the module to provide quick and easy connector to the relay contacts. On-line order cart and further details can be found at http://www.j-
