Termination of connector style I/O
I/O connectors should be 20-pin type and conform to MIL C 83503 of Military Standard.
This type of connector is also used for FX
2C
series programmable controllers.
3.13
Termination of Terminal style I/O
The output connectors of the main unit and the connector-type 16-point output extension
blocks are 16-point common type (8-point common type for the FX
2NC
-16MT).
These output connectors have two +V0 to +V2 pins that are connected to each other inside
the programmable controller. To connect the line to an external unit, shortcircuit these two
pins at the external circuit so that the load of each pin can be reduced.
Observe the following cautions, and properly wire the I/O cables of the terminal style FX
2NC
PLC.
If you do not observe the following cautions, electrical shock, shortcircuit, disconnection
and damages in the unit may be caused.
•
Make sure that the end of each cable is treated into the size shown in Fig. 3.14.
•
Twist the end of each stranded cable so that barbed wires are not present.
•
Never solder the end of any cables.
•
Never connect cables whose size is not allowed. Make sure that the number of
connected cables is not more than a specified number.
•
Fix cables so that the stress is not directly applied on the terminal block and the cable
connection area.
