Scope of the power supply for the transmission cable
To implement the AnyWire Bitty system, all conditions specified by the following calculation formulas 1) to 3) have to
be met.
(1) Description of calculation formula 1)
(a) Related constant of non-isolated slave modules (Ihin, Iho)
For non-isolated slave modules, current required for the internal control circuit and connected load is supplied
through the transmission cable (DP, DN).
Ihin(A)
= Current consumption of non-isolated input slave module/I/O combined slave module
= Current consumption of non-isolated input slave module/I/O combined slave Current consumption
of connected load (three-wire sensor)
Number of points
Iho(A)
= Current consumption of non-isolated output slave module
= Current consumption of non-isolated output slave Current consumption of connected load
Number of points
●
The 24VL and 0VL terminals of a slave module are used to supply the power to the connected load. For details, refer to
the manual for the slave module used.
●
For the current consumption of non-isolated slave modules, refer to the manual for the slave module used.
