• Multi I/O Module expands the metering capabilities of G4400 Series Power Quality Analyzers
• I/O module includes analog and digital I/O as well as a relay output
• UART RS232 for interfacing with GPS enhanced synchronization (IRIG-1PPs)
• G4400 series supports up to (2) I/O modules using internal power
• I/O modules should be installed at Elspec Laboratory 

The G4400 Series offers the option to expand 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 equipment. The G4400 series supports up to (2) I/O modules using internal power along with:

• 8 fast digital input at 16 sample/sec
• 4 fast digital output at 16 sample/sec
• 4 analog 4-20mA input sampled at 1Hz with programmable scaling
• 4 analog 4-20mA output
• 3 Relays
