EMC Professional 3011

19 inch time server with integrated radio time receiver for industrial environments

EMC Professional 3011 is a radio time receiver for PC networks. The device delivers the atomic radio time based on DCF77 signal to the entire network by its integrated NTP server. It disposes of a BNC interface for connection of an external active antenna. In case of reception interferences, an internal temperature compensated real time clock continues to run. The sensor interface allows monitoring of ambient temperature of this 19-inch device by optional available sensors.
