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.
