PRC-101 Redundancy Switch Controller

The PRC-101 is a multipurpose redundancy switch controller for encoders, modulators, up/downconverters, LBN/LNA and HPA in 1:1 redundancy configuration. The controller monitors alarm signals and switches to a stand-by unit in the event of unit failure. It has a dual power supply.


Configured as a 19-inch rack unit, the controller functions are operated using a display window and a keypad on the front panel. An LED light indicates the unit’s alarm status, while data in/ out ports are located at the rear. The PRC-101 can operate in automatic or manual mode and can be remotely controlled with an RS232, RS485 or IP interface. The controller is equipped with a dual power supply, to safeguard reliability and uninterrupted service.
