The above table contents the information required about limits and equivalences of the references to
determine the maximum number of devices to be connected by loop and Control panel.
EXAMPLE: It is wanted to connect 15 MDA1Y and 50 A30XHA. The 15 MDA1Y equivalence is 75
elements, and 50 A30XHA is 50. Total of 125 elements. It can not be installed as it is overcomed the limit of
99 elements per loop.
In the same way, it must be checked the maximum number of devices, the logic relays and the loop
isolators, including total number of them by Control Panel. This task can be performed using EASYcoNET
software.
Note: the limits of the system can be above of the limits shown in the previous table. It can be made
consults to Technical Service to know the system limit of a specific configuration.
