Save valuable rack space without sacrificing alarm capacity: The NetGuardian 432 has 32 discrete point inputs, 4 control relays, and an optional D-Wire input supporting up to 16 analog sensors.


Key Features

  • 4 control relays for controlling site equipment and security devices
  • 32 Discrete Alarm Points - Cover your entire site with a single unit
  • Built-in web interface for unit configuration and standalone monitoring

The NetGuardian 432 RTU maximizes alarm coverage in a single rack unit, allowing you to monitor 32 discrete alarm points. The unit's dense discrete coverage saves you the cost and trouble of installing multiple lower-capacity RTUs at sites with a lot of alarms to capture.

The unit also comes standard with 4 form C control relays and a serial port, both of which provide remote control and access to your remote sites. You can operate controls through the web interface and use the unit's serial port to reach-through into serial-only equipment onsite.

You can also customize your NetGuardian 432 with a D-Wire sensor port and internal temperature sensor. The D-Wire port allows you to connect up to 16 analog sensors (in series) to your NetGuardian. D-Wire sensors are all powered by the NetGuardian as well, allowing you to extend a chain of sensors up to 600 feet from your RTU.

The NetGuardian's web interface makes provisioning your RTU and monitoring alarms quick and easy. You can operate control relays, configure your NetGuardian to send SNMP traps to multiple alarm masters or SNMP managers, and set up email notifications from alarms all from any computer on your network.

Benefits of the NetGuardian 432 G4:

  • 32 discrete alarm points
  • 4 (Form C) control relays
  • Notifications via email or SNMP
  • Support for 16 D-Wire sensors
  • Fast and easy-to-use web interface
  • Dual -48 VDC power inputs (for improved reliability)
  • Rack or wall mounted

The NetGuardian 432 G4 provides the discrete capacity to handle almost any site, without sacrificing control relays to fully manage your remote locations.
