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.
