The DNF-4-1G is a compact, rugged and highly integrated Ethernet I/ O data acquisition platform. Its 1U FLATRACK form-factor provides a low-profile footprint for space-constrained applications that require up to four I/O boards per chassis. The platform is ideal for applications in which point-to-point signal conditioning and patch panel connections can be avoided. Its backplane electronics are identical to UEI's popular PowerDNR RACKtangle series. The DNF-4-1G series provides two Gigabit Ethernet (100/10 Base-T compatible) interfaces and front-loading slots for quick and easy implementation and configurability. These capabilities enhance usability, improve performance and simplify I/O reconfiguration. The backplane within the rack contains no active electronic components, ensuring that the platform delivers high availability (maximum MTBF and minimum MTTR) in mission-critical applications.
