Remote Terminal Units (RTU) for Monitoring and Control

RTUs for virtually any need

What do you need your RTU to do? At DPS, we specialize in helping you with challenging projects. You'll find dozens of off-the-shelf RTUs, and you can even get custom RTUs if you really need something unique.

RTUs like these enable you to remotely monitoring and control your facilities and equipment. You can collect self-reported equipment alarms and environmentals (temperature, humidity, smoke, water, etc.). You can track door and motion alarms. You can activate backup systems. If you want to monitor or control something without actually being there, there's probably a way to do it with a remote terminal unit.

An RTU with a big range of I/O

Let's take a look at this RTU to begin: the NetGuardian 832A. It's a good example, because it does a lot of things. If you understand this 832A, you understand remote terminal units.

Remote Terminal Unit with a variety of inputs and outputs
The NetGuardian 832A G5 has discrete inputs, analog inputs, control relays, a terminal server, +12v sensor power, dual NICs, dual power inputs, and an integrated 10/100BaseT switch. Full Description & Specs

RTU Features of the NG 832A:


An RTU for small sites

Sometimes you only need a few inputs and outputs. There's no need to waste budget dollars on capacity you'll never use. The NetGuardian LT is a good solution in this scenario. With 2-4 discrete inputs, 1 analog, and 1 control, it provides reliable monitoring without going overkill on I/O.

Small RTU for sites with limited requirements
The NetGuardian LT is a small remote terminal unit for locations that don't need a ton of monitoring. It's great for a few equipment alarms and a temperature sensor, for example.Full Description & Specs

An RTU with built-in T1

Here's a medium-sized remote terminal unit with native T1 support (FrameRelay or PPP): the NetGuardian 216T. This is handy at outside-plant sites (especially microwave sites) where you don't have LAN. The included network switch also breaks out LAN for other devices. You know that's an incredibly valuable feature if you work with T1-only buildings.

The NetGuardian 216T supports T1 natively. It can then provide normal LAN for other devices at the site.Full Description & Specs

There is no other network on the planet that is exactly like yours. For that reason, you need to build a monitoring system that's the right fit for you.

"Buying more than you need" and "buying less than you need" are real risks. You also have to think about training, tech support, and upgrade availability.

Make an Informed Decision


Your network isn't off-the-shelf.

Your monitoring system shouldn't be, either.
