SC4-HUB
The SC4-HUB connects your computer and I/O devices to your ClearPath-
SC motors. The SC Hub routes communication signals, passes
sensor/switch inputs to the motors, includes 2 power-off brake outputs ,
and one Global Stop (e-stop) input. A maximum of 4 SC Hubs can be
linked together to create systems of up to 16 axes per port, and up to 3
ports per computer, allowing you to create systems with as many as 48
motion axes.

UPPLY
The DC Bus Power Supply provides main power to your ClearPath-SC
motors. A Teknic IPC-5, 75VDC supply is shown above, but ClearPath-SC
motors can be powered from other supplies in the 24–75VDC range.
POWER4-HUB
The POWER4-HUB distributes DC bus power and backup logic power to
as many as four ClearPath-SC motors per hub. If DC bus power is
suddenly lost, the Power Hub will automatically switch to auxiliary logic
power to maintain uninterrupted power to the processor, memory, and
communication circuits. Multiple Power Hubs can be chained together to
support larger systems.
