Traditionally, mounted on the generator is a panel showing AC parameters. Additional design, components, wiring, assembly and test adds to the cost of manufacture. In the field, it becomes a source of numerous potential failures and servicing. The RIO 425 is designed to replace this drain on resources for both maker and end user. It is fitted in the alternator terminal box, with appropriate standard turn down transformers, connected to each phase of the alternator, taking its power from these connections. That is it. The RIO 425 then communicates directly with the 200 or 400 series DCU via a simple twisted pair signalling wire. The DCU’s are pre configured to recognise the RIO, and will automatically add another page to the DCU pages dedicated to AC information. No programming, no configuring, no graphic set up, just connect.
All the key parameters are developed and displayed on the DCU by the RIO 425. Line and phase voltages, frequency, power factor, KVA/Kw, and of course currents. Critically though, the DCU also puts these values into its broadcast messages, and enables them to be communicated to third party systems via Modbus for example. No analogue or digital converters required
In summary the RIO 425 is a low technical risk and an exceedingly cost effective way to integrate AC parameters into displays for your generating sets. Reduce manufacturing, commissioning and in service costs, and provide a real value added solution to your equipment by specifying the RIO 425.
