As the most compact member of the NetGuardian family, the NetGuardian 216 G3 offers an easy, cost-effective way to monitor your small sites.

The NetGuardian 216 G3 comes with 16 discrete alarm inputs, 2 or 8 analog inputs, and 2 control relay outputs. The discrete alarms can be used for items such as door alarms, equipment alarms, and other ON/OFF events. The analog alarms are used for measuring such critical events as temperature and voltage. The controls are a convenient and time-efficient way of remotely switching equipment in the field via the NetGuardianā€™s internal relays.

The NetGuardian 216 G3 reports alarms via SNMP, DCP, DCPf, or DCPx over either UDP or TCP and can be used with your T/Mon master station or an SNMP manager.

The reach-through serial port provides you with the ability to access a remote serial device via LAN using a terminal server. Now you also have the option of ordering your unit with temperature sensors and/or a wireless modem. With the built-in Real Time Clock, the NetGuardian will time/date stamp incoming SNMP traps. It will also remember the current date and time settings during power failures.
