Eliminating the task of manually switching cables, relay devices act as on-off bus switches to connect and disconnect individual remote terminals or entire bus segments to/from a bus network.
Stub Switching Relays
Stub switching relays allow an external DC control signal to engage and disengage a stub from the bus network.
Bus Switching Relays
Bus switching relays allow an external DC control signal to toggle the input between two different remotely-coupled bus connections.
Bus Segmenting Relays
Bus segmentation relays allow an external DC control signal to toggle which bus the input is directly connected to. The unused bus is terminated inside the relay with an appropriate load to prevent network failure.
