Features

	Loader Communication Port
	Data can be viewed on site by using the display and operation keys or controlled remotely via loader communication port. The SB1 has a display, setting keys and loader communication port on the front panel.


	Power-saving by SB Link
	Peak current suppression (SB Link)
	When SB1 controllers are divided into groups (max. 4 pcs per group) with the output limiter, the controllers in the same group will not turn on simultaneously. Saves energy by limiting the control output around the normal load factor. * SB Link cannot be used simultaneously with a host communication.


	Safety design
	< Load Power Shutoff Function + Fuse >
	This function disconnects internal load power with an internal relay. A fuse is incorporated inside the SB1 to protect the instrument from a load short-circuit.
