4.2 S−LINK Main Power Supply
4.2 S−LINK Main Power Supply
In order to supply power to the various S−LINK devices, an external power supply must
be connected to the S−LINK unit and power supplied through that source.
This is the power supply for the S−LINK controller in the S−LINK unit and S−LINK I/O
devices to which power is supplied through the 24V − 0V line of the S−LINK main cable.
The current consumption for the overall S−LINK system is calculated by referring to the
section entitled "Determining the Power Supply" in the "S−LINK Design Manual." (For
standard purposes, a power supply exceeding 24V DC, 1.6 A should be selected.)
Example:
The power supply is connected to "IN 24V − 0V" on the S−LINK
terminal block.

Note
The S−LINK is protected by a fuse, but if too many input/output
devices are connected, or if the current consumption is heavy
enough to cause the fuse to blow, we recommend providing a
local power supply.
