RFL GARD Pro® Single Function PLC System
Brand: RFL Electronics
Catalog ID: RFL-GARD-Pro-PLC
The GARD Pro PLC is designed for use with directional comparison blocking (DCB), direct transfer trip (DTT), Unblocking (DCUB), permissive (PTT), or either single- or dual-phase comparison protection schemes. The extensive sequence of events and diagnostic features provide information for the GARD Pro and integrated PLC modules.The system is available in both a 3U chassis size supporting one PLC interfaces, or a 6U supporting up to four PLC interfaces. 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.
