* When using the VIA terminal as contact input terminals in sink logic connection, be sure to insert a
resistor between the P24 terminal and the VIA terminal. (Recommended resistance: 4.7k
Ω-1/2W)
Note: When using the VIA terminal as a contact input terminal, be sure to turn the VIA (SW3) slide switch to
the V position.
+ The figure on the right shows an example of the
connection of input terminal VIA when it is used as
contact input terminal. This example illustrates the
connection when the inverter is used in sink
(Negative) logic mode.
