NOTES
1 Up to four input devices can be connected to each G terminal. Do not connect three or more wires
togheter to one terminal.
2 Use micro-current contacts for no-voltage input contacts. (Voltage and current to be at DC 16 V and
below 10 mA with the contact closed)
3 The order of connections may flexibility be modified depending on the test-run settngs.
With a combination of OPDI, Di-2 and Di-3, total of 18 input devices can be connected.
