The NetGuardian 16A Can Maximize Your Analog Coverage Within A Single RU.

The NetGuardian 16A maximizes analog capacity in a single RU

The NetGuardian 16A comes standard with 16 user-configurable analog inputs - our highest capacity offering in a single RU. Connect sensors to measure temperature, humidity, wind speed, direction, generator fuel levels, and other quantities without installing multiple RTUs or adding 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, freeing up the analog input you would've used to monitor the NetGuardian's local temperature.

In addition to the NetGuardian 16A's standard analog inputs, the unit also includes a D-Wire sensor port, allowing you to connect another 16 sensors to the NetGuardian. D-Wire sensors measure temperature and humidity at present (with more sensor types coming soon), just like your analog sensors, and are connected 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.

Features At A Glance.

  • 16 analog inputs in a single rack unit size.
  • 2 additional analog inputs to monitor power input feeds.
  • 4 form C control relays.
  • 20 discrete inputs.
  • 16 ping targets.
  • Serial port.
  • Optional integrated temperature sensor for local monitoring.
  • LAN or NetGuardian web interface configurations.

You don't have to sacrifice for your added analog capacity either, because the NetGuardian 16A comes with 20 discrete inputs and 4 control relays. With the NetGuardian 16A, you can monitor all the analogs you need, while still monitoring dry contacts from your equipment and operating controls as necessary.

With the NetGuardian's serial port, you can also provide reach-through access to LAN inaccessible equipment at your site.

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 notifications your NetGuardian will send in the event of alarm conditions.

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

What Is A Rack Unit, Why It Matters.

Now, you might be wondering about the term RU if you aren't already familiar with it. RU is an acronym for rack unit and a rack unit (RU) is a unit of measurement that denotes how much space, vertically, the equipment will occupy on an equipment rack. Racks are made to more or less stack a bunch of equipment on top of each other for efficient use of the space available. Most racks are usually 19'' or 23'' in width and the numbers of rack-mountable equipment that can be stacked on the rack is measured in one RU and is usually written as 1U. 1U is equal to 1.75 inches in height and a typical rack can support 42U which is a little bit more than 6 feet of equipment.

A Far-fetched Example Of A 42U Rack Having 42 NetGuardian 16A.

Here's a highly unlikely but simplified example for visualizing what 1U is. The NetGuardian 16A takes up 1U, a single RU, which is 1.75 inches. A rack that can support up to 42U is able to have room for comfortably mounting 42 NetGuardians 16A. Although, the rack might actually be taller than 42U in height, it should still be able to handle 42U worth of equipment being mounted onto it.

Better Have More Resources Than Not Enough..

Let's start off with a simple question. Would you rather have more resources or not enough? The logical answer to that question would, of course, be yes. To have more resources versus not having enough is a no-brainer. A type of resource that most people always give second thoughts to until it really matters is space. Would you rather have more space or not enough? And again, more is always better than not having enough.

Leave More Space For Your Gear With The 1U NetGuardian 16A.

Because there is only so much space available on a rack, all of the equipment that is needed has to fit on the rack. When a monitoring system needs more capability than what the current space would allow. One of the first option would be to build more racks to hold more equipment. That works, but what if there is just no possible way to do that. There is no more space for building new racks. Well, a much better solution would be to do more with less space. That's what products like the NetGuardian 16A does best, by providing more functionality in less the space. Replace an old analog input monitor that uses 2U of space with the NetGuardian 16A which takes up only 1U of space.
