(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, O2 senser input and contact input should be fixed
separately from power supply wiring and contact output wiring.
(6) Communication interface: connector for communication (RS-232C interface)
• Please refer to the manual (IM 11G02P01-01E) about communication function.
