Chapter 3 System Configuration
This chapter describes the method of system configuration and characteristics.
3.1 Notices in Selecting Module
Here describes the notices in selecting digital I/O module which is used for Remote I/O.
1) Digital input types contain the current sink input and current source input
.
In case of DC input module, as the wiring method
of external input power is different according to such input types, make sure of selecting the input module considering the
spec. of input connection machine. The wiring method per type is as follows.
(1) How to connect the sink type external connection machine to the source type DC input module.

External connection machine is located between DC power and (-) terminal of DC input module terminal.

Thus, when inputting ON, the current flows from DC input module terminal to external connection machine.
(2) How to connect the source type external connection machine to the sink type DC input module.

External connection machine is located between DC power and (+) terminal of DC input module terminal.

Thus, when inputting ON, the current flows from external connection machine to DC input module terminal.
2) In case that the open/close frequency is high or it is used to open/close the conductive load, please use transistor output module
as Relay output module may reduce the life.
