Each of the NetGuardian 16's analog channels may be individually configured to monitor analog changes in your
environment. The analog inputs natively measures voltage on a range of -90 to +90 VDC. By removing the lid of the
unit, you can move a jumper to set the point to monitor 4 - 20mA.
Internal and external temperature sensors monitor the ambient temperature. Both sensors measure a range of 32° F
to 140° F (0° C to 60° C) within an accuracy of ± 1°. The external temperature sensor provides external temperature
readings by plugging the optional probe into the temperature port on the NetGuardian 16's back panel.
