ABB’s DC-drive documentation gives the eight digital inputs, eight digital outputs, four analog inputs, two analog outputs, and three voltage/current reference outputs. The digital inputs accept either 110 VAC or 24 VDC control voltage, while the analog section provides differential inputs and 12-bit-plus-sign resolution.
Product Introduction
The ABB 3ASD573001A5 is an extended mixed-I/O board used with compatible ABB legacy DC drive control systems. Rather than acting as the main drive controller or power-conversion stage, it expands the controller’s interface to field devices by combining discrete and analog signal handling on one board. ABB documentation places the within its legacy DC-drive portfolio, including YGMV, YGMW, YHMV, and YHMW product families.
The provides eight optically isolated digital inputs, eight digital outputs, four differential analog inputs, two analog outputs, and dedicated reference outputs. This combination makes the board useful where drive control logic needs to exchange both discrete status/control signals and continuously variable process values with external equipment. Its mixed-I/O design is especially relevant when maintaining older drive installations where the original control architecture remains operational and exact spare-board matching is preferable to redesigning the interface.

Application Scenarios & Field Pitfalls — The Engineer’s Perspective
Engineering Pain Point
With older ABB DC drives, an I/O board failure can stop an otherwise healthy drive because the board may carry permissives, interlocks, speed references, feedback-related signals, relay commands, and other machine interfaces. Replacing the with a generic I/O assembly is not a practical solution because the electrical interface and original application configuration are tied to the ABB drive-control architecture.
Typical Applications
- ABB legacy DC drive systems — Extended I/O for compatible YGMV, YGMW, YHMV, and YHMW drive families.
- Industrial motor control — Interface for digital machine signals and analog process/drive references.
- Machine interlocks — Relay and transistor outputs can interface with contactors, relays, and other control circuits.
- Process signal acquisition — Differential analog inputs accept voltage or current signals for drive-related measurements and commands.
Technical Pitfalls
1. Do not confuse with a power stack.
Some secondary product pages incorrectly describe 3ASD573001A5 as an ACS880 IGBT power-stack component. ABB’s own documentation identifies it as the Mixed I/O Board and places it in the legacy DC-drive portfolio.
2. The digital input voltage is configuration-relevant.
The eight inputs support 110 VAC or 24 VDC control voltage. Before wiring a replacement, verify the actual field circuit voltage rather than assuming that all eight inputs are being used at 24 VDC.
3. Relay and transistor outputs are not equivalent.
Six outputs use normally open relay contacts with a maximum 230 VAC / 2 A rating, while two outputs are optically isolated transistor outputs rated to 60 VDC / 100 mA. Do not substitute one output type for another when tracing an existing control circuit.
4. Analog input scaling must be preserved.
The analog inputs support ±10 V and ±20 mA as primary ranges, with other ranges available through software scaling. When replacing the board, document the existing signal type and scaling before returning the drive to service.
5. Check the I/O bus architecture.
ABB documents the as an extended I/O board connected through a parallel bus, with up to four boards for extended I/O. Remote I/O uses a different low-speed serial-bus arrangement. The installation architecture should therefore be checked before assuming that another YPQ-family board can occupy the same position.
6. Do not overlook the reference outputs.
The board provides +10 V, -10 V, and 5 mA references. These may be used by surrounding control circuitry, so a replacement should be checked against the cabinet drawings rather than evaluated only by counting I/O channels.
7. The board is legacy hardware.
ABB’s product data identifies 3ASD573001A5 as no longer for sale. This makes revision control and spare-stock planning important for plants still operating compatible ABB DC drives.

Procurement Note
For ABB / 3ASD573001A5, use the complete ABB type designation and product ID when sourcing. Verify the installed drive family, board position, field wiring, input voltage, relay/transistor output usage, analog signal ranges, and I/O-bus arrangement before accepting a replacement.
For used or surplus boards, visual inspection should be followed by electrical testing of the relay contacts, transistor outputs, analog channels, digital input isolation, and reference outputs where suitable test equipment is available. Also inspect terminal connectors and PCB condition for heat damage or corrosion.
If the original board is still functional, record the field wiring and software scaling before removal. With a legacy DC-drive system, recovering the original signal configuration after an unplanned board failure can take considerably longer than installing the replacement itself.
