7. Connecting EXT–I/O Cable
7.1 Connecting EXT–I/O Cable
The EXT–I/O cable is used to connect the TR48DIOCN/TR48DIOC module (option)
or Toshiba Machine's designated remote I/O module (option) serving as the slave
station.
To supply the controller internal power to the TR48DIOCN/TR48DIOC module, the
EXT–I/O cable is connected with P24V (24 V) and P24G (0 V). (The maximum
allowable current capacity of the remote I/O module is 1.2 A in total.)
If the current exceeds the maximum current capacity of 3 A (including the external
I/O) when the internal power supply is used, use an external power supply that can
supply both 24 V and 0 V.
NEVER use the internal power supply together with the external power supply.
Otherwise, the power supply may be damaged.
