The DNR-FAN-925 is an auxiliary cooling fan board for use with UEI’s popular RACKtangle™ I/O chassis. The fan board is designed for use with the DNR-AI-256 high output, Synchro/Resolver/RVDT/LVDT board (fan included with purchase of DNR-AI-256). Simply install the FAN-925 in the slot to the right of the DNR-AI-256 and it will provide all cooling required. The 29.0 dB-A fan is exceptionally quiet and will not noticeably increase ambient noise.

The fan is designed to run any time the Cube/RACK is powered up. The API provides diagnostics and allows the host PC to read the board’s power supply voltage and current as well as the fan RPM.

Software included with the DNR-FAN-925 provides a comprehensive yet easy to use API that supports all popular Windows programming languages as well as supporting programmers using Linux and most real-time operating systems including QNX, RTX, VXworks and more. Additionally, the UEIDAQ Framework supplies complete support for those creating applications in Windows based data acquisition software packages such as LabVIEW, MATLAB/Simulink, or any application which supports ActiveX or OPC servers.
