Power Supply
General precautions Introduction While installing the yellow AS-i cable, it is essential to place it in a cable track which is separate from the power cables. It is also advisable to place it flat and not twisted. This will help make the two AS-i cable wires as symmetrical as possible. Installing the AS-i cable on a surface connected to the electric potential of the machine (for example, the housing) complies with the requirements of the EMC (Electro Magnetic Compatibility) directive. The end of the cable, or the ends in the case of a bus with a star-formation , must be protected either:
by connecting it (them) to a T-derivation, by not allowing them to come out of their last connection point.
Important It is important to distribute power effectively on the AS-i bus, so that each device on the bus is supplied with sufficient voltage to enable it to operate properly. To do this, certain rules must be followed. Rule 1 Select the capacity of the supply module adapted to the total consumption of the AS-i segment. Available capacities are 2.4 A (TSX SUP A02) and 5 A (TSX SUP A05). A capacity of 2.4 A is generally sufficient based on an average consumption of 65mA per slave for a segment made up of a maximum of 31 slaves.
