ABB SS832 3BSC610068R1 Power Module
NDIO-02 Digital I/OExtension Module
The Digital I/O Extension Module (NDIO) offers two digital inputs
(24 to 250 V d.c., or 110 to 230 V a.c.) and two relay outputs
(2000 VA/250 V a.c. or 8 A/24 V d.c.).
Delivery Check The option package contains:
• NDIO-02 module
• three pairs of fibre optic cables (120/370/2000 mm)
• mounting rail (DIN 50022, 35 × 7.5 mm, length 45 mm)
• This manual, the NTAC-0x/NDIO-0x/NAIO-0x Installation and
Start-up Guide.
Compatibility The NDIO-02 is compatible with the following application programs:
• ACS 600 Standard Application Program version 2.8 or later
• ACS 600 System Application Program version 4.2 or later
• ACS 600 Crane Drive Application Program version 5.0 or later
• ACS 600 Application Program Template (all versions).
NAIO-03 Analogue I/O
Extension Module
The Analogue I/O Extension Module (NAIO) offers two bipolar current
(±0(4) to 20 mA) or voltage (±0(2) to 10 V, or ±0 to 2 V) inputs and two
unipolar current (0(4) to 20 mA) outputs. The signal resolution (12 bits)
is better than that of the standard analogue I/O.
Delivery Check The option package contains:
• NAIO-03 module
• three pairs of fibre optic cables (120/370/2000 mm)
• mounting rail (DIN 50022, 35 × 7.5 mm, length 45 mm)
• This manual, the NTAC-0x/NDIO-0x/NAIO-0x Installation and
Start-up Guide.
Compatibility The NAIO-03 is compatible with the following application programs:
• ACS 600 Standard Application Program version 2.8 or later
• ACS 600 System Application Program version 4.2 or later
• ACS 600 Crane Drive Application Program version 5.0 or later
• ACS 600 Application Program Template (all versions).
Warranty See the Hardware Manual of the drive for information on warranty.

Mechanical Installation Depending on the drive, the module(s) can be installed either inside or
outside the drive housing or cabinet. See the Hardware Manual of the
drive for module placement options.
Mounting Outside
the Drive
Choose the location for the module. Note the following:
• The cabling instructions (given later in this chapter for each module
type) must be followed. Also, the length of the fibre optic cables
included in the option package may restrict the distance between
the module and the drive.
• Observe the free space requirements for the module (min. 10 mm
from adjoining equipment or wall) and the drive (see the drive
documentation).
• The ambient conditions must be taken into account (see
Appendix B). The degree of protection of the module is IP 20.
• Module earth is connected to the mounting rail by means of an
earthing clip (see Figure 3-2 below). The mounting rail onto which
the module is to be mounted must be earthed to a noiseless earth. If
the rail is not mounted on a properly earthed base, a separate
earthing conductor must be used. The conductor must be as short
as possible and the cross-sectional area must be 6 mm2 at least.
Note: No solid copper conductor may be used (stranded wire
allowed only).
Mounting instructions:
1. Switch off all dangerous voltages in the enclosure that the module
is to be mounted in.
2. Fasten the rail and ensure proper earthing as described above.
3. Push the module onto the rail. The module can be released by
pulling the locking spring with a screwdriver (see Figure 3-2).
