AHUB-8 - Signals Hub

Signals hub AHUB-8 allows to multiply RS485 communication port into 8 galvanic separated ports. This allows to connect up to 8 different devices working on RS485 hub on different potentials and with different current-voltage input parameters. The device is made as intrinsically safe and can be used in mining plants in chambers with danger of methane and / or coal dust explosion. AHUB-8 signals hub is available with supply voltage from 6 to 12 VDC (in version AHUB-8/1) or from 8 to 16 VDC (in version AHUB-8/2). Casing protection degree is only IP20, therefore it is necessary to place the device in casing with protection degree at least IP54 to provide safety in environment endangered with explosion.
