(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 module + 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 module + Current consumption of connected load 
Number of points

power supply
● 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.

I(A) = (Ihin  m) + (Iho  n) + (Izdin  p) + (Izdo  q)  The maximum value of the transmission cable supply current
The number of connected modules by type: m, n, p, q
Vm(V) - V(V)  20V
Vm(V) - V(V)  The lowest limit of the allowable voltage range for connected load
