The NRG Symphonie Field Wiring Panel is an input protection device required to connect NRG sensors to the NRG Symphonie 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 Symphonie Field Wiring Panel will divert the energy to Earth Ground, protecting the NRG Symphonie data logger from damage. Severe ESD events may require replacement of the NRG Symphonie Field Wiring Panel to restore normal data logging operations.

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

For SymphoniePLUS 15-channel data loggers, a different Field Wiring Panel is required, see Kit# 4296.
