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 NetGuardian’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.
