BALLUFF Hub BNI007Z Selection Conditions

BALLUFF Hub BNI007Z Selection Conditions

Shell material PA, transparent, nickel plated grounding plate (Sn 2... 4 µ m)

Size 50 x 30.8 x 115 mm

Environmental temperature -20... 70 ° C

Due to the fact that hubs regenerate or amplify any received digital signals and submit them through all ports of the hub, there is a high chance of signal collision, and signals may also be affected. This means that all devices connected to the hub belong to the same collision domain and broadcast domain. Therefore, most hubs have been replaced by switches.

Protection level IP67, with tightened bolts

Transmission rate COM2 (38.4 kBaud)

Process data cycle, 3.5 ms

Process data input 2 bytes

Hubs are pure hardware network underlying devices that basically do not have the 'intelligent memory' and 'learning' capabilities similar to switches. It also does not have the MAC address table that switches have, so when it sends data, it is not targeted and instead uses broadcast transmission. That is to say, when it wants to send data to a certain node, it does not directly send the data to the destination node, but sends the data packet to all nodes connected to the hub, as shown in the figure, which is simple and clear.
