JSB342 8Amp SPDT Relay with Optocoupler Inputs Module

The JSB342 USB Digital Input with Opto-Isolation with SPDT 8 Amp relays provides an optically isolated inputs for connections to user devices such as sensors or switches. The inputs senses DC voltage that can be read from the host PC, while providing full isolation. This eliminates surges present in industrial environments from effecting the host PC. The SPDT relay outputs provide host control between a common line, normally open, and close connections point.
Single unit cost starts at USD$ 92.5

Most of our customers write their own program for controlling our devices. With our provided API's you can use any programming language that supports DLL so you do not have to learn a whole new language. We provide two types of DLL api, first is the older standard DLL with both mangled calls and "C" calls. The second is the managed Class Library that supports all the new managed languages. Any programming language that supports calls to Windows DLL can also be used to control the cards. The software interface is easy to use from Visual Basic, Visual C# Visual C++ via a standard windows DLL with sample source included. Linux driver support CD available. Each module has an unique serial number string which allows multiple USB boards to be controlled by the host USB controller as individual USB devices.
