■Constants related to the isolation slave module (Izdin, Izdo)
In the isolation slave module, only the current required for the internal control circuit is supplied with the transmission cables
(DP, DN), whereas that for the connected load is supplied from the power cables (24V, 0V).
■Izdin(A): Current consumption of the isolation input slave module/I/O combined slave module
■Izdo(A): Current consumption of the isolation output slave module

(5) Connected load
• In isolation slave modules, the current consumption of the connected load is not subject to the current
restriction condition for the AnyWireASLINK system.
• For the current consumption of isolation slave modules, refer to the manual for the slave module used.
■Transmission cable supply current (I(A))
The transmission cable supply current in the AnyWireASLINK system is determined by the following formula. (Number of
connected modules: m, n, p, q)
I(A) = (Ihin m) + (Iho n) + (Izdin p) + (Izdo q)
■Maximum transmission cable supply current
For the maximum transmission cable supply current, refer to the following.
