■ Serial Transmission with B7A Link Terminal
A series of models incorporating a communications (serial transmission) function is available.
By using the B7A Link Terminal (PLC connector model), the Units can be connected to the PLC with ease. The 16-point B7A Link Terminal allows
the control of a maximum of four digits over two wires.
Available Link Terminal Models
Transmission Path
Transmission distance:
A maximum transmission distance of 500 m is
possible by using the VCTF 0.75 x 2C Cable if
power is supplied independently to the Input and
Output Link Terminals.
A maximum transmission distance of 100 m is
possible by using the VCTF 0.75 x 3C Cable if a
single power supply is connected to the Input or
Output Link Terminal, in which case the current
flow on the power lines (positive and negative
lines) is 1.8 A maximum.
Transmission delay:
A maximum of 50 ms for data display after the
B7A's input signal becomes definite.
Minimum Input Time
Use an input time of 80 ms min. to the Input
Unit for the B7A.
