Which RTU (Remote Telemetry Unit) Features Do You Need?

The factors to take into consideration when choosing Remote Terminal Units (RTUs) for a remote SCADA system might be overwhelming. There are many device options out there claiming they are the best ones for your remote monitoring and control system.

Hardware and software solutions that offer multiple pre-configured features are now available with enough capacity to handle multiple different scenarios.

How do you find the right RTU (Remote Telemetry Unit)? Here are 5 essential features to look for:

1. Discrete alarms: Monitor device failures, intrusion alarms, beacons, and flood and fire detectors.

2. Analog alarm inputs: Monitor voltage, temperature, humidity and pressure.

3. Control relays: Operate remote site equipment directly from your SCADA master.

4. Redundant backup communication: Backup serial ports and/or internal modems will keep your monitoring online even during a LAN failure.

5. Redundant backup power inputs: Dual power inputs and battery backup keep monitoring online, even during power failures.

DPS Telecom offers RTUs that meet all these requirements - and offer local visibility via Web browser, email, pager notifications, and more.

The examples above are just a few of the applications where a RTU can be used. Please give us a call so that we can discuss in more depth how we can customize a solution to fit your needs.

Our Technical Sales team can work with you to get you what you need. We have a vast array of experience in numerous industries such as Telecom, Public Safety, Public Transit, Utilities, Government, Military and so much more. DPS Telecom's specialty is consolidating all your needs into one box. Giving you the opportunity to maximize time and cut down expenses.

NetGuardian 832

The NetGuardian 832A G5 was designed with the previous features in mind, especially to be able to handle all the requirements of medium/large remote sites.

Here are some of its features:

  • High Capacity: 32 discrete alarms (expandable to 176), 32 ping alarms, 8 analog alarms, 8 controls, and 8 serial ports for monitoring remote sites.
  • Reports alarms via SNMP v2c or DCPX.
  • Reports alarms to a lot of SNMP managers or TMon Remote Alarm Monitoring System so it's easier than every to support a more secure redundant master architecture.
  • Dual Ethernet support for secure network access, both NICs have access to the NetGuardian but not to each other.
  • 8 high-speed (110K) serial ports provide multiple user LAN-based reach. This is through access to PBXs, switches, and any other device with a craft port or serial only interface. (Similar to terminal serve functionality)
  • Integrated 4 port hub allows functionality with the NetGuardian SiteCAM for visual site surveillance.
  • Alarm point grouping provides severity levels, custom virtual alarms and more.
  • RoHS 5 approved, for overseas clients requiring RoHS compliant units.
  • Alternate dial-up reporting path for continuous remote site monitoring in case of a main communication path failure.
  • Configure the NetGuardian and monitor your remote sites via Web RTU browser
  • E-mail and pager alerts.
  • Free lifetime firmware upgrades
  • Free Windows-based utility for off-site editing and remote provisioning via LAN
