SCADA Guardian 848: Overview

The analog-dense, DNP3 capable SCADA guardian 848
The Scada Guardian supports up to 24 analog sensors and reports in DNP3 or SNMP, for easy integration into your SCADA network.

A SCADA environment relies heavily on accurate information from a wide range of variables to ensure that each part of a controlled process happens when it should and to the right degree.

The SCADA Guardian 848, the latest remote telemetry unit (RTU) from DPS Telecom is designed specifically to make sure your SCADA operation gets the necessary information to keep things running smoothly.

This new RTU is densely packed, capable of monitoring 24 external analog sensors, so you can monitor temperature, flow, pressure, and any other number of variables to keep your SCADA controlled environment running smoothly. Of the analog inputs, 16 are based on DPS Telecom's convenient "D-Wire" technology, in which the sensor's power and monitoring data are both carried through the same cable. The D-Wire inputs allow you to chain sensors together, and extend a sensor up to 600 feet from the SCADA Guardian, allowing you to monitor variables in multiple areas of your SCADA environment without installing new RTUs every few feet.

For integration into your particular SCADA platform, you can order your SCADA Guardian 848 with either DNP3 or SNMP reporting options. Being able to choose between protocols means you won't have to use a mediation device to integrate the RTU you want into the SCADA system you have.

In addition to the plethora of analog inputs, the SCADA Guardian 848 also monitors 8 discrete contacts, providing visibility for your equipment in addition to the process environment. It also has 4 control relays, allowing you to remotely control equipment as necessary.

The unit is also built with a serial port, enabling reach-through access over LAN to your serial only equipment. This way you don't have to install a separate switch, or, worse, make a trip out to your remote site to access your serial equipment.

If you need heavy analog coverage in your SCADA environment, look no further than the DNP3 or SNMP capable SCADA Guardian 848.

The Analog Coverage You Need in the Protocol of Your Choice:

  • Your Choice of DNP3 or SNMP reporting.
  • 24 Analog Inputs.
    • 8 Standard analog inputs.
    • 16 D-Wire analog channels.
  • 1 Internal Temperature Sensor.
  • 8 Discrete Contacts.
  • 4 Control Relays.
  • Receive 24/7 email notifications for threshold or discrete alarms.
  • Built-in web interface to monitor your RTU from any PC on the network.

SCADA Guardian D-Wire application
Easily monitor critical analog values by daisy chaining D-Wire sensors. D-wire sensors are available for monitoring temperature, humidity, and many more environmental levels. Some D-wire nodes can provide extra discrete/analog inputs. Daisy chains can exceed a dozen sensors.
