# Power Supply To The Anywireaslink System - Mitsubishi Electric MELSEC-Q Series User Manual

6.2.3

## Power supply to the AnyWireASLINK system

(1) Method of supplying the power to the slave module
Connect a 24VDC external power supply to the master module.
The power consumed in the internal control circuits of all the slave modules and the external load power
connected to non-isolated slave modules are supplied collectively from the 24VDC external power supply
connected to the master modules.
( Page 26, Section 3.2)
(2) Scope of the power supply with transmission cables (DP and DN)
The current consumption of the system must satisfy all the conditions specified by the following calculation
formulas 1) to 3) for each master module.
Condition
Calculation formula
I(A) = (Ihin x m) + (Iho x n) + (Izdin x
1)
p) + (Izdo x q)  The maximum value
of transmission cable supply current
2)
Vm(V) - V(V)  20V
Vm(V) - V(V)  The lowest
3)
allowable voltage of the connected
Ihin: Current consumption of the non-isolated input slave module/I/O combined slave
module
Iho: Current consumption of the non-isolated output slave module
Izdin: Current consumption of the isolated input slave module/I/O combined slave
module
Izdo: Current consumption of the isolated output slave module
m: Number of connected non-isolated input slave modules/I/O combined slave
modules
n: Number of connected non-isolated output slave modules
p: Number of connected isolated input slave modules/I/O combined slave modules
q: Number of connected isolated output slave modules
For details, refer to Page 48, Section 6.2.3 (2) (a).
Vm: Supply voltage for the master module
V: Cable-to-cable voltage drop
