What This Option Board
Provides
The optional I/O Expansion circuit board
(1)
is mounted on the control board of
the drive and provides these additional I/O signals:
•
Four Digital Inputs
•
Four Digital Outputs
•
Two Analog Outputs
This circuit board is catalog number 20P-S5V62.

I/O Expansion Board Wiring
Table 90 - Recommended Signal Wire Size
A 75 x 2.5 x 0.4 mm (3.0 x 0.1 x 0.02 in.) flathead screwdriver is recommended
for connecting wire to the terminal block inputs. Strip the ends of the cables to a
length of 6.5 mm (0.26 in.).
(1) The Analog and Digital I/O Expansion circuit board is not factory installed.

IMPORTANT
To improve the noise immunity it is recommended that you connect the
common of the outputs (terminals 2, 4, 5 and 15 of the I/O Expansion board)
with the ground (terminal 10 or 20) on the standard I/O terminal blocks on the
control board. If this is not possible, these terminals must be grounded by
means of a 0.1 mf/250V capacitor.
