Note: 1. The transmission distance values stated in this table are based on one power supply attached to each Input or Output Link
Terminal. If two Input or Output Link Terminals share one power supply, the transmission distance will be derated, and the volt-
age must be 24 VDC
±10%.
The derated transmission distance for normal--speed models is 100 m maximum and that of a
high--speed model is 50 m maximum. Additional information on power supply connections follows in Operation section.
2. A shielded transmission cable or plain twisted pair cable with a thickness of 0.75 mm
2
minimum must be used for signal
transmission. If twisted pair cable is used, however, the transmission distance will be 10 m maximum regardless of whether or
not independent power supplies for the Input and the Output Link Terminals are used.
3. The minimum input time is required for the B7A/B7AS to read an input signal.
4. For high-speed models, these values are possible without grounding the shielded line.
