The NetGuardian 16A: Maximizing Analog Coverage in a Single Rack Unit

NetGuardian 16A
The NetGuardian 16A maximizes analog capacity in a single RU.

Monitoring a complex process or SCADA operation used to need loads of expensive monitoring gear and several RUs of space to manage.

The difference between analog inputs and discrete inputs.

Unless what you are monitoring only requires simple yes/no, on/off, type of readings, you are most likely going to need analogs. Analogs work differently than discretes in that they use a scale to display information. It would be hard to measure temperature with a discrete, which can only display one of two answers. But with an analog, you can have a scale of temperatures, so that you know exactly what is going on at your site. Temperature is not the only thing that you can measure this way. Voltages, LPG levels, humidity levels and other SCADA related metrics need a scaled reading rather than a binary one. Analogs allow for more accurate measurements so that you have better visibility of your site.

In the past, if you needed to monitor voltage, temp, humidity, fuel levels, pressure, and other non-binary values, you needed loads of analog inputs. To get the extra analog inputs you needed, you had to install a lot of RTUs. Often times, increasing your analog capacity crowded out standard monitoring functions too, like discrete inputs and control relays. You had to choose between cost and rack space savings and the monitoring info you needed to monitor and control your process.

The NetGuardian 16A: Maximize your analog coverage and other remote telemetry unit functions with just one single rack unit.

But now you can maximize your analog input capacity in a single RU without sacrificing alarm inputs, space, or your operating budget. Meet the NetGuardian 16A.

The NetGuardian 16A supports 32 analog sensor inputs (16 analog, 16 D-Wire), and can send SNMP and email alerts for alarms.

The NetGuardian 16A comes standard with 16 analog inputs. This is our highest capacity offering in a single RU. Connect sensors to measure temp, humidity, wind speed, direction, generator fuel levels, and other quantities without installing a lot of RTUs or expansions. These 16 inputs are in addition to 2 internal high-impedance analogs for power feed voltage monitoring. The unit also comes with an integrated temperature sensor. This opens up the analog input you would've used to monitor the NetGuardian's local temperature.

The NetGuardian 16A offers more than just analog inputs.

In addition to the NetGuardian 16A's standard analog inputs, the unit also includes a D-Wire sensor port. This allows you to connect another 16 sensors to the NetGuardian. D-Wire sensors measure temperature, humidity, voltages, wind speed and more. This is just like your analog sensors, and are joined to and powered by your NetGuardian over simple RJ-11 connections. You can extend up to 16 sensors in a daisy chain up to 800 feet in length from the NetGuardian.

You don't have to sacrifice for your added analog capacity either. The NetGuardian 16A comes with 20 discrete inputs and 4 control relays. With the discretes, you will be alerted when the power is on/off, if your generator or batteries are running, and many other metrics measured in a binary way. The controls will allow you to turn on the generator if your site loses commercial power and more. With the NetGuardian 16A, you can monitor all the analogs you need, while still monitoring dry contacts from your gear and operating controls as needed.

With the NetGuardian's serial port, you can also provide reach-through access to LAN inaccessible gear at your site. All your gear will work together as one seamlessly integrated system for maximum site visibility.

You will database and monitor your new NetGuardian 16A through the unit's easy-to-navigate web interface. Through the web interface, you'll configure threshold alarms for all of the unit's analogs, alarm descriptions, and configure what sorts of alerts your NetGuardian will send in the event of alarm conditions.

The NetGuardian 16A can send SNMP traps to your SNMP master station. It can also send emails containing full alarm descriptions and point references. It can talk directly with the T/Mon alarm master system. When an alarm condition occurs, your NetGuardian 16A will make sure you hear about it.

The NetGuardian 16A also supports several other protocols. You can seamlessly integrate it into the rest of your network infrastructure, including legacy gear.
