The GARD Pro® Single Function PLC channel is a product that can be programmed as Frequency-Shift Keyed (FSK) power line carrier system or as an amplitude-modulated ON/OFF powerline carrier terminal.
The unit is designed for pilot protection relaying applications, requiring high-speed reliable communications. The GARD Pro® can be programmed for On/Off type directional comparison blocking (DCB), direct transfer trip, (DTT) Unblocking (DCU), permissive (PTT), or either single- or dual-phase comparison applications.
The extensive sequence of events and diagnostic features provide information for the GARD Pro® and integrated PLC modules. The chassis is available in both a 3U version which can support one PLC system, or a 6U version which can support up to four PLC systems.
The unit is available with front panel direct reading (in dB) digital meter to indicate receive signal strength. Each unit also comes with an external carrier level indicator output for use with external measuring devices such as a panel meter or an analog RTU input.
Now supports DNP3 and SNMP remote management protocols for integration with management systems.
New product features include:
- DNP3 Support
- Includes binary inputs, binary outputs, analog inputs and counters
- New binary input points for all logical SOE triggers
- Improved DNP performance with faster response time and sensitivity
- Connections for up to three masters; two TCP/IP and one serial RS-485
- SNMP Support
- Sends SNMP traps to 1-5 receivers
- SNMP "Get" with v3 authenticated access for all system configuration parameters
New Web Browser Interface
The GARD Pro® System is designed with ease-of-use in mind. While high functionality and great detail is provided, the GARD Pro® User Interface makes interaction with the device highly intuitive and handling greatly simplified.
All interaction with the GARD Pro® System is made by the use of a standard web browser. The web pages reside in the device: no special application software is required on the PC.
A PC is connected to the front Ethernet TCP/IP port with a standard Ethernet cable. It is fast and simple to view device status, access diagnostic and test functions and to change settings. Emulating the operations of a standard web site, navigation is intuitive and eliminates the need to study written instructions. If needed, the instruction manual, that also resides in the device, is simply accessed by the HELP function.
For off-line preparation of settings and configuration files, a small application program "emulating" a GARD Pro® System can reside on a PC or local server. Archiving and documenting settings and configuration is made simple as these are stored in standard text files.
New - Touch Screen Display Interface
The GARD Pro® is available with an optional Touch Screen Display (TSD) Interface that provides the ability to monitor system status and SOE, and perform calibration and testing functions without connecting your PC.
The GARD Pro® TSD user interface is all new with redesigned pages keeping ease-of-use in mind. Status pages will now provide live information without the need to manually refresh.
The new GARD Pro® TSD includes Powerline Carrier commissioning functionality. This provides the ability to calibrate the PLC receiver from the TSD without the use of a PC allowing the ability to commission the unit from the front panel.
