The G4400 series offers the option to expend the meter capability by adding the multi I/O module in conjunction with all metering functionalities. The I/O module includes analog and digital I/O as well as a relay output to specifically work with your application.The multi I/O module extends the meter capability in order to replace RTUs and PLCs for energy management and substation automation. With the G4400 series you can monitor the reliability of system apparatus such as transformers, circuit breakers and other critical equipments. The G4400 series supports up to 2 I/O modules using internal power along with:a 8 fast digital input at 16sample/seca 4 fast digital output at 16 sample/seca 4 analog 4-20mA input sampled at 1Hz with programmable scalinga 4 analog 4-20mA outputa 3 Relays

The G4400 series is accessible locally or remotely, using either an integral web server interface or the Elspec G4100 remote display. The Elspec G4100 represents the next generation in power network information exchange.By using IP based communication, various unprecedented setup configurations are enabled over a great distance. Using ethernet infrastructure, the G4100 can monitor multiple G4400 meters connected to the network remotely or connected to each analyzer directly. The G4100’s display provides full control over all meters allowing technicians and field operators to fully configure and operate each single meter in the network. The G4100 can be powered by external power supply or through the G4400 embedded PoE port.

The GPS provides an optimal mobile time synchronization solution for accurate time data via satellite signal. In absence of any other available technologies, it synchronizes the time at any remote location.
