Contact Input/Output Terminal
The contact signal is input or output from the control output terminal block or the control
DIO expansion terminal block indicated in the following figure.

As shown in the following figure, contact input terminals (DIGITAL IN) and contact output
terminals (DIGITAL OUT) are arranged on each terminal block. There are two types of
contact outputs: relay output and transistor output. For the connection procedure of the
signal wires, see section 2.3, “Wiring”.

Prescribed operation such as stop/run operation can be performed using contact inputs.
Selecting Terminal Blocks and Terminals
The control output terminal block allows 6 contact inputs; the control DIO expansion
terminal block allows 12 contact inputs. Select the terminal block for registering the
contact input information by specifying “CTRL1-2,” “CTRL3-4,” “CTRL5-6,” and
“EXTDIO” for the loop 1 and 2 control output terminal block, the loop 3 and 4 control
output terminal block, the loop 5 and 6 control output terminal block, and control DIO
expansion terminal block, respectively. The following contact input numbers are used to
select the contact inputs on each terminal block.
Contact input of the loop 1 and 2 control output terminal block: DI001 to DI006
Contact input of loop 3 and 4 control output terminal block: DI101 to DI106
Contact input of loop 5 and 6 control output terminal block: DI201 to DI206
Contact input of the control DIO expansion terminal block: RI001 to RI012
