ABB DSDP170K02 3BSE019925R1 Pulse Counter Module

Technical Specifications Model: DSDP170K02, Part No. 3BSE019925R1 System Compatibility: ABB Advant Master DCS System Input Channel Quantity: 4 pulse input channels Input Signal Level: 24 V DC Maximum Input Pulse Frequency: 100 kHz Counter Register: 32‑bit Isolation: Group‑wise galvanic isolation Power Supply: From rack backplane Mounting: Eurocard rack plug‑in Operating Temperature: 0 ℃ to +60 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5‑95 %, non‑condensing Protection Class: IP20 Certifications: CE

Functional Features Four independent high‑speed pulse input channels support pulse counting and frequency measurement functions. 32‑bit hardware counter realizes long‑time pulse accumulation without short‑term overflow. Configurable counting direction, filter parameters and hardware gate control mode. Group‑wise galvanic isolation suppresses field‑side common‑mode electromagnetic interference. Front‑panel LED indicators reflect signal input status and module running condition. Built‑in hardware self‑diagnosis monitors power supply status and internal circuit faults. Supports hot‑swap operation under permitted Advant Master maintenance workflow.

Application Scenarios Spare‑part replacement project for DSDP170K02 3BSE019925R1 pulse counter module. Pulse signal collection for flowmeters and encoders in legacy Advant Master DCS cabinets. Industrial sites requiring high‑speed pulse counting and flow totalizer calculation.

Installation Requirements Insert DSDP170K02 3BSE019925R1 into target rack slot and tighten front locking screw. Connect field pulse sensor shielded twisted‑pair cables to front screw terminals and tighten to specified torque. Configure counting mode, filter time and gate parameters through Advant engineering software. Implement protective earthing complying with Advant Master grounding specification. Pulse signal cables must be separated from high‑power power cables inside cabinet. Reserve heat‑dissipation ventilation space around module slot. Ambient operating temperature shall keep within 0 ℃ ~ +60 ℃ without condensation.

Usage Notes Input pulse signal voltage shall comply with 24 V DC rated specification. Actual input pulse frequency cannot exceed maximum rated 100 kHz.
