3-4-1 Wiring the Power Supply to the Gateway Unit
Power (24 VDC) is supplied directly from a power source to the Gateway Unit.
Precautions for Correct Use
Do not allow the wiring between the Gateway Unit and the power supply to exceed 3 m.
z
Selecting a DC Power Supply
The DC power supply must satisfy the following conditions.
For Slave Units with network power supply, the power for external I/O is also supplied from the
power supply connected to the Gateway Unit (through the Flat Cable). When determining the output
current of the power supply, always include the actual load currents and the current consumptions of
the external I/O.
Refer to documentation for each Slave Unit for information on Slave Unit current consumptions.
Item Specification
Output voltage 24 VDC
±
10%
Output ripple 600 mVp-p
Output current The capacity of the power supply must be equal to the sum of the
following current consumptions or greater.
•
Current consumptions of all Word Slave Units and Repeater Units
• Current consumptions of all Bit Slave Units plus the current
consumptions of the external I/O
Isolation The output must be isolated from both the AC power supply and the
case ground.
