Digital Inputs ( I )
The iSmart digital input points are designated as I contacts. The number of digital input points is 6, 8 or 12
depending on each iSmart model.
Keypad Inputs ( Z )
The iSmart keypad input points are designated as Z contacts. The number of keypad input points is 4 which only
exist on SMT CD type model and ED type model.
D
igital Outputs ( Q )
The iSmart digital output points are designated as Q coils/contacts. The number of digital output points is 4 or 8
depending on each iSmart model. In this example, output point Q01 will be turned on when input point I01 is
activated.
