INTERFACE MANUAL 
      (When the external power is supplied to the remote I/O module and only the 
RS485 communication cable is extended, the total cable length can be 400 
m or less.) 
  • Characteristic impedance : 100 
Ω 
    •  Others  :  For RS485 250 kbps data communication. 
    Recommended twisted pair cable with shield 
    TKVVBS 0.3 sq. 
× 2 P (made by Tachii Densen) 
    NEVER use a cable which does not conform to the specifications.    Otherwise, 
short-circuit or cable melting due to overheated cable core may be caused.   
Additionally, the robot may work improperly due to noise. 
  b.  When connecting two (2) TR48DIOCN/TR48DIOC modules for I/O extension, 
be sure to branch from the terminal block of slave station 0, as shown in Fig. 
7.2.    (For the I/O extension, up to two (2) TR48DIOCN/TR48DIOC modules 
can be connected.) 
  For details on the TR48DIOCN/TR48DIOC module, see the Simple PLC Function 
Manual.
