The NRG SymphoniePLUS Field Wiring Panel is an input protection device required to connect NRG sensors to the NRG SymphoniePLUS data logger. This panel features integrated gas tube surge arrestors to protect sensitive data logger circuitry from electrostatic discharge (ESD) events.

In the event of a lightning strike (ESD), the NRG SymphoniePLUS Field Wiring Panel will divert the energy to Earth Ground, protecting the NRG SymphoniePLUS data logger from damage. Severe ESD events may require replacement of the NRG SymphoniePLUS Field Wiring Panel to restore normal data logging operations.

NRG Systems recommends carrying a spare SymphoniePLUS Field Wiring Panel when performing site visits.

For Symphonie 12-channel data loggers, a different Field Wiring Panel is required, see Kit# 3704.
