ABB DSRF197-3BSE019297R1 – Relay I/O Module for Advant/800xA Control Cabinets

The ABB DSRF197 (part no. 3BSE019297R1) is a rack-mounted relay interface module used in ABB distributed control systems, typically within Advant and 800xA-based cabinets. From my experience, teams use this module as a dry-contact relay output stage to switch interposing circuits, solenoids, and permissive signals where galvanic isolation and clean contact behavior really matter. You might notice that it streamlines field wiring, because channel isolation and the backplane integration remove a lot of ad‑hoc relays from the panel.

Order Placement Process and Guarantees

• Warranty: 365 days
• Lead time: 1 week if in stock; no more than 1 month at the latest
• Payment terms: 50% advance payment; full payment prior to delivery
• Express options: FedEx, UPS, DHL

Key Features

• Relay output interface – Provides isolated dry contacts suited for interlocks, permissives, and actuator control.
• Backplane integration – Communicates via the ABB rack backplane, so no external communication wiring is needed.
• Cabinet-friendly form factor – Single-width, plug-in construction helps maximize cabinet density and simplify service.
• Field wiring convenience – Typically paired with proven terminal bases, keeping installation tidy and repeatable.
• Industrial robustness – Designed for DCS environments where electrical noise and continuous duty are the norm.
• Lifecycle support – Commonly used across brownfield ABB systems, easing replacements and spares strategies.

Technical Specifications

Application Fields

The DSRF197 is commonly applied wherever ABB DCS platforms need reliable relay outputs. Typical scenarios include:

• Process plants (chemicals, oil & gas, power) for interlocks, permissives, and ESD tie-ins
• Pulp & paper and metals for motor starter commands and MCC handshakes
• Water & wastewater for valve actuation and pump staging via interposing contacts
• OEM skids integrated into 800xA/Advant cabinets needing galvanic isolation to field devices

Advantages & Value

• Reliability in the loop – Relay isolation helps protect the controller side from field disturbances.
• Compatibility – Fits established ABB rack ecosystems, reducing engineering and commissioning time.
• Lifecycle savings – In many cases, this module drops in as a like‑for‑like spare, minimizing rewiring and downtime.
• Technical support – We can assist with part identification, version checks, and cabinet fit-up, which typically speeds approvals.

One thing I appreciate is how straightforward troubleshooting becomes: if a channel shows wear, it’s usually a quick swap without disturbing the rest of the rack. A maintenance supervisor from a power plant told us, “We replaced two DSRF modules during a short outage—back online in under an hour with clean signaling again.”

Installation & Maintenance

• Cabinet standards – Install in a clean, ventilated enclosure (IEC/UL-rated). Keep ambient within typical DCS ranges.
• Rack location – Mount in the designated ABB rack slot; ensure backplane connector alignment before seating.
• Wiring – Use properly rated field conductors; segregate high-voltage and signal wiring. Torque terminals per ABB guidelines.
• Earthing – Maintain cabinet grounding and shield terminations to reduce noise pickup.
• Safety – De-energize circuits before insertion/removal unless the system explicitly supports live replacement procedures.
• Routine checks – Periodically verify contact operation, clean dust from ventilation paths, and review firmware or configuration baselines where applicable.

Quality & Certifications

• CE-compliant; many production batches are UL Recognized and RoHS-aligned
• Manufactured under ISO 9001 quality systems (ABB)
• 12-month warranty (365 days)

Suggested Supporting Components

For a clean install, teams typically pair the DSRF197 with the appropriate ABB rack/terminal base for your cabinet standard, plus labeled field terminal blocks and interposing fuses or breakers where the site standard requires them. If you share your existing rack type and slot plan, we can validate form/fit and recommend spare quantities.
