Digital Inputs ( I )
The SG2 digital input points are designated as I contacts. The number of digital input points is 6, 8 or 12
depending on each SG2 model.
Keypad Inputs ( Z )
The SG2 keypad input points are designated as Z contacts. The number of keypad input points is 4 which only
exist on SG2 H type model and V type model.
Digital Outputs ( Q )
The SG2 digital output points are designated as Q coils/contacts. The number of digital output points is 4 or 8
depending on each SG2 model. In this example, output point Q01 will be turned on when input point I01 is activated.
