*1 This is the value when a shielded cable is used. If no shielded cable is used,
the maximum transmission distance will be 10 m, regardless of the method
used to supply power.
*2 The least input time is the least time required for the B7A Interface Unit to
read an input signal.
*3 This is induced noise due to coupling with the transmission line. For
high-speed transmission, this is the value when the shield is not grounded.
The function of each part of the B7A Interface Unit is indicated below.
Be sure to switch OFF the power supply to both the NT30/30C and the B7A Inter-
face Unit before installing the B7A Interface Unit, otherwise the Units may be
damaged.
When the B7A Interface Unit is installed, the depth of the NT30/30C is increased
by 20 mm to 76 mm. Before installing the B7A Unit, check that there is sufficient
space inside the operation panel to accommodate this extra depth.
(1) Peel off the label on the right side of the rear face of the NT30/30C. Under-
neath the label are the connector and screw holes for installing the B7A In-
terface Unit.
