Dynamometer Automation Application:

Amajor manuacturer o dynamometers has standardized on thePowerDNA cube as the I/O system used to monitor and controltheir large dynos. The dynamometers are sold to customers world-

wide and are used in a wide variety o automotive, aircrat and rail-

road applications testing both engine perormance as well as brake

perormance.

Previous systems had been based on shipping a dynamometer to

the customer site in two pieces, the mechanical machine and the

control racks. Company installation technicians then placed the

dyno and the control racks in place and went through the tedious

and time consuming task o connecting the hundreds o control and

monitoring wires between the control rack and the dynamometer.

The PowerDNAs combination o high density I/O, combined with its

environmental ruggedness allows the entire I/O system to be mount-

ed directly on the dynamometer. In the new conguration, when the

units are installed at a customer acility, the dyno is installed and the

host computer is placed in the control room. The eld technicians

then need only connect power, and Ethernet to the dynamometer.

The application was developed in C, and run on standard Windows

operating systems. The PowerDNA products used in a

include:
