(4) Contact input (DI): terminal block 2, 13 to 20 , terminal block 3, 5 to 10 .
•
It is for a contact input at no voltage. An input is provided when switching to short circuit
(on) or open (off).
•
No voltage is applied to the terminals.
(5) Contact output (DO): terminal block 3, 13 to 20 , terminal block 4 and terminal block 5
•
Contact rating : 250 V AC/2 A, load resistance
•
An output is for a relay contact output. An output is provided when switching to conductive
(on) or open (off).
Note) The wires of analog output signals, O 2 senser input and contact input should be fixed
separately from power supply wiring and contact output wiring.
