Description

 ABB DSDP170K02 is a 4-channel High‑Speed Pulse / Quadrature Encoder Counter Board

Model: DSDP170K02 | Part No: 3BSE019925R1

Product Title & Description

The ABB DSDP170K02 is a 4-channel High‑Speed Pulse / Quadrature Encoder Counter Board, part of ABB Advant OCS / MasterPiece S100 I/O rack family. It captures high-frequency incremental encoder and pulse signals for precision speed, position and length measurement. Widely used in pulp & paper, metal rolling mills, power plants and chemical process lines. It is the top-tier high-speed counter card in DSDP series, successor of DSDP140B/DSDP150/DSDP160, critical spare for legacy Advant DCS maintenance & retrofit.

Core Product Overview

DSDP170K02 is 4-channel independent pulse/quadrature encoder board.

• Max pulse frequency: 2.5 MHz
• Supports 1x / 2x / 4x / 8x quadrature counting modes
• Accepts 5–24VDC differential / single-ended encoder/pulse signals
• Each channel performs local pulse accumulation, frequency calculation, scaling and filtering
• Front panel LED indicators for module health and channel status
• Built-in diagnostics: wire break, signal loss, overrange fault detection
• Communicates to ABB MasterPiece AC100/AC160/AC450 controllers via S100 rack backplane bus

Lifecycle note: DSDP170K02 is discontinued. Only available as NOS or refurbished spare for existing Advant OCS systems.

Q2: How many encoder channels can handle? A2: 4 independent channels, each can be configured as pulse frequency or quadrature position input.

Q3: Is still in production? A3: Discontinued. Only NOS and refurbished spare available for legacy Advant system maintenance.

Q4: What kind of sensors can connect to ? A4: Incremental rotary encoders, high-speed pulse flow meters, high-frequency MPU magnetic pickups.

Q5: Warranty for original ABB 3BSE019925R1? A5: Original / refurbished unit carries standard 12-month factory warranty under proper installation and operating conditions.

Installation & Configuration Guide

7.1 Pre-installation Preparation

Verify board, inspect backplane connector and front LED indicators. Prepare shielded differential encoder cables, Advant rack, encoders or pulse sensors. Power off rack before installation, wear ESD protection.

7.2 Installation Steps

Insert into empty rack slot and lock the module. Wire field encoder/pulse signals with shielded twisted pair (differential recommended), single-point shield grounding inside control cabinet. Check rack backplane power and protective earthing, ensure cabinet ventilation.

7.3 System Configuration & Commissioning

Power up rack, check module LED status. Configure each channel: counting mode (1x/2x/4x/8x), pulse scaling, filter and alarm thresholds in Advant engineering tool. Simulate high-speed pulse/encoder signal to verify counting accuracy and wire-break fault alarm. Confirm speed/position/length values transmit to Advant controller. Save system configuration database.

7.4 Maintenance & Precautions

During plant outage, inspect wiring terminals, cable shielding and PCB dust accumulation. Keep cabinet clean. If counting jump or lost pulses occurs, check encoder, cable shielding, differential signal wiring and grounding before replacing .
