4.2 S-LINK Main Power Supply
4.2.1 Role and Connection of S-LINK Main Power Supply
Role
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 24 V - 0 V 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 24 V DC, 1.6 A should be selected.)
Connection
The power supply is connected to “IN 24 V - 0 V” 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.
