The NNZ-2A is used for protecting TML-NET network measurement system from induced lightning. When the cable of instrument or network-module receives induced lightning, failure may be caused in the network driver and/or network module by the lightning surge. The NNZ-2A is connected to the connection cable of the network, and works to flow the surge current to the earth when induced lightning occurs. In addition, during standby of measurement, it automatically shuts off the network line to protect the network driver and network modules from the lightning surge.


Shuts off network line automatically during measurement standby status to avoid induced current
Power is supplied from network line
