RSB2084 2 or 4 8 Amp Latching SPST Relay Module

The RSB2084 USB Relay board provides 2 or 4 Latching SPST relays for connection to user devices. The SPST relays outputs provide host control between a common line and normally open connection point. A latching relay has two relaxed states (bistable). These relays are called impulse, keep or stay types. When the power is switched off the relays, the relay remains in its last state. The relay retains the last state during any power outages, and will only switch when command to by the host PC.With the onboard latching relays, the last command state of the relay is maintained even after power has been removed from the board. Wire connection to the module relay contacts is with screw type high quality terminal blocks. Single unit cost starts at $90 . RSB2084 2 or 4 8 Amp Latching SPST Relay Module

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.
