The UDIN-8I is a low-cost USB relay and digital I/O unit for desk-top, panel or industrial DIN rail mounting. It features 8 x fully opto-isolated digital inputs. The inputs can accept a 5-24V DC voltage or a volt free contact. The UDIN-8I does not require any external PSU as power is derived from the USB port..

The UDIN-8I can be desktop, panel or DIN rail mount. The unit will clip on to standard 35mm DIN rail. The DIN rail mounting clips may be extended to reveal 4mm screw holes for fixing to a panel or wall.


Most software packages that can send or receive ASCII data to a RS232 port should be able to control the UDIN-8I. The UDIN-8I units comes with a Virtual Com Port driver, which installs a "Virtual" Com port on the PC. Software can then send and receive ASCII data to and from this Virtual Com port and thus to the UDIN-8I unit. Typical packages that can be used include Windows HyperTerminal (and most other terminal emulator packages), data acquisition packages such as Profilab, DAQFactory, etc. and also most SCADA Software packages.

Programmers can bypass the VCP route, and use direct .DLL function calls instead. The UDIN units are supplied with a test application complete with all source code. Drivers are available for the Windows operating system, Linux, MAC and Win CE.NET

The UDIN-8I can be tested using the simple test application complete with all source code. This VB example is written using the Visual Studio environment and required the .NET framework version 2 to run.

Also available is a demo application written using ProfiLab package which can be used to control the relay manually or on a timed basis. No programming experience is needed to use ProfiLab and programs are written by connecting function blocks together with wires. Professional user panels can be designed with custom controls, and the whole program can be compiled into a stand-alone executable file, with no run-time penalties.
