The SILBUS network bridge type SILBUS-SNB1 is an explosion protected DIN railmounting module that allows for two SILBUS networks to exchange channel data or information but remain electrically independent or galvanically isolated from each other. The network bridge allows for the exchange of data on a single channel or on multiple channels. The exchange of data can be between channels of the same address or be mapped to be between different channels on each network. The data exchange can be uni or bi-directional.
