The 128ASL-M supplies the internal power supply of slave modules and the connection load power
supply of non-isolated slave modules from transmission signals.
The following expression shows the rough value of the transmission cable supply current (A):
Transmission cable supply current = Internal current consumption of slave modules + Maximum
On some slave modules with cables, the cross-sectional area of the integrated transmission cables
(DP, DN) is 0.75mm
sectional area of normal transmission cables (DP, DN) meets the following requirements.
For slave modules with integrated transmission cables (DP, DN), the length of the transmission cables
(DP, DN) is included in the total length.
