ABB DSDP170 (57160001-ADF) – System I/O Distribution/Termination Board for Advant DCS

The ABB DSDP170, ordering code 57160001-ADF, is a spare-part board widely used in ABB Advant-based DCS installations as a distribution/termination interface for process I/O. In many cases it sits between the field wiring and the controller/remote I/O stack, helping route signals and power in a clean, serviceable way. One thing I appreciate is how it tends to keep legacy Advant I/O stations running with minimal rewiring—especially helpful during phased upgrades or quick-change maintenance windows.

From my experience, the DSDP170 is selected when teams need form-fit-function replacement inside existing Advant stations, maintaining compatibility with paired digital and analog I/O modules. You might notice that it’s designed to be backplane powered and doesn’t require separate field supply beyond what the I/O station already provides, which typically simplifies cabinet design and reduces points of failure.

Order Placement Process and Guarantees

• Warranty: 365 days
• Delivery: 1 week for in‑stock items; no more than one month at the latest
• Payment: 50% advance payment, full payment prior to delivery
• Express options: FedEx, UPS, DHL

Typical workflow: you share the required quantity and site details → we confirm exact revision/compatibility → proforma invoice issued → advance payment received → outbound testing and packing → shipment booking and tracking shared.

Key Features

• Advant I/O distribution and termination: Designed to route field signals within ABB Advant DCS stations, aiding clean wiring and fast service.
• Backplane powered: Typically powered from the system backplane, avoiding extra external supplies and reducing wiring complexity.
• Compatibility-focused design: Intended as a form-fit replacement in many Advant setups using matched digital/analog I/O modules.
• Serviceable layout: Clear terminal mapping supports faster swaps and simplifies troubleshooting during planned shutdowns.
• Robust build for industrial cabinets: Components and PCB layout emphasize cabinet reliability and EMI/EMC resilience in most cases.

A maintenance supervisor from a chemical plant told us their team swapped a DSDP170 during a night shift and had the line back up in under an hour—no rewiring beyond terminal move-and-mark.

Application Fields

The DSDP170-57160001-ADF is typically found in:

• Refining and petrochemical units where legacy Advant I/O remains in service
• Pharmaceutical batch lines requiring orderly field wiring and validated change control
• Pulp and paper mills with staged migration from Advant to newer ABB platforms
• Power and utilities balance-of-plant cabinets where downtime windows are tight

Advantages & Value for Procurement

• Continuity of operation: Keeps existing Advant I/O stations running, reducing retrofit scope and risk.
• Compatibility and form-fit: Appears to be designed for direct replacement in many Advant cabinets, limiting design changes.
• Lower lifecycle cost: Minimizes engineering and field wiring labor versus a wholesale I/O platform swap.
• Tested spares support: We can arrange pre-shipment functional checks and provide traceable test reports when requested.

Installation & Maintenance

• Cabinet environment: Install in a clean, ventilated control cabinet; follow ABB grounding and shielding practices to limit EMI.
• Mounting: Seat the board firmly in its designated station slot; check backplane connector engagement before power-up.
• Wiring: Use correctly sized, ferrule-terminated conductors; maintain separation between signal and power wiring; label terminals for future service.
• Safety: De-energize the station; observe ESD precautions; verify isolation before handling field conductors.
• Routine care: Periodic visual inspection for loose terminals and dust; gentle dry-air cleaning; no user firmware on this board—backup the station configuration as standard practice.

Quality & Certifications

• Certifications: ABB products of this class are typically CE marked; many builds comply with RoHS and are produced under ISO 9001 quality systems. UL applicability depends on the complete cabinet/system listing.
• Manufacturer warranty: Standard ABB terms may apply in original system supply.
• Our coverage: 365-day warranty on the supplied unit as stated above.

Commonly Paired Components (for planning)

To help with spares planning, teams often check stock on related Advant I/O items at the same time:

• DSDI series – digital input modules used in Advant stations
• DSDO series – digital output modules for discrete control
• DSAI series – analog input modules for process signals
• Advant controllers/backplanes – to confirm slot and revision compatibility during replacement

If you can share your existing station type and any label photos of the installed board, we can double-check the 57160001-ADF revision against your system before shipment. That little step usually prevents surprises onsite.
