ABB PDP22-FBP

ABB PDP22-FBP

Product Brief:​ The PDP22-FBP (often part of ABB’s FieldBus Power Conditioner / Linking Device family — also marketed as FBP / LD800 series) is a segment coupler + power conditioner that connects one or two FOUNDATION Fieldbus H1 segments (31.25 kbps) to a higher-level network — typically PROFIBUS DP-V1 (to AC 800M CI854 or S+ node) or Ethernet (Modbus TCP). It supplies the intrinsic safety (if IS version) or non-IS power to the FF H1 segment, conditions the signal, and passes function block data transparently. The “FBP” suffix denotes the integrated power conditioner + linking device in one enclosure (vs. separate PC + LD800).

Description

ABB PDP22-FBP

  • Technical Specifications (typical LD800 / PDP22-FBP):
    • H1 Ports: 1 or 2 × FF H1 (31.25 kbps); each supports up to 16 devices (max 32 per spec, recommended ≤16 for margin)
    • H1 Power: Integrated Power Conditioner — 24 V DC input → regulated 24 V DC on H1 with 30–90 mA available for field devices (IS barrier version: MTL or Pepperl+FuchsIS barrier internal)
    • Host Interface: PROFIBUS DP-V1 Slave (9-pin D-sub) or Ethernet 10/100 Mbps (Modbus TCP / FF HSE — model dependent)
    • PROFIBUS DP Baud: 9.6 kbps – 12 Mbps auto; GSD file provided
    • Function Block Support: Transparent — FF function blocks execute in field devices; linker passes data each macrocycle
    • Alarms & Diagnostics: Device fail, segment short, power loss, comm error reported via host network; local LEDs (Power, Com, H1 Active, Fault)
    • Power Supply Input: 100–240 V AC or 24 V DC (model dependent)
    • Enclosure: IP20 (DIN-rail) or IP54 (wall-mount field enclosure for IS version)
    • Operating Temp.: –20 °C to +60 °C
    • Certifications: FM, CSA, ATEX (IS version: Ex ia IIC T4/T6), CE, IEC 61784-1/2
  • Functional Features:
    • Built-in FF power conditioner — no separate PC800 needed (in FBP combo unit)
    • IS version allows direct connection to Zone 0/1 FF H1 devices (with appropriate entity parameter check)
    • Redundant Linking Device pairs supported (some models)
    • Time distribution to FF segment (via Link Active Scheduler — LAS function in linker)
    • Device discovery & capability file (CFF) download via host engineering tool (ABB Control Builder / DeltaV/ other FF host)
  • Application Scenarios:
    • Integrate FF H1 field instruments (pressure, temperature, flow, valve positioners with FF) into ABB 800xA / Symphony Plus via PROFIBUS DP or Modbus TCP
    • Retrofit of legacy analog I/O to FF — keep instruments, add linker to connect to modern DCS
    • Oil & gas / chemical plant — multiple FF segments per process unit, each on its own PDP22-FBP H1 port
  • Material & Structure / Working Principle / Installation / Precautions:
    • DIN-rail mount in system cabinet (non-IS) or field junction box (IS version — purge/explosion-proof as required)
    • Wire H1 segment to H1+ / H1– terminals; observe polarity; terminate both ends of H1 trunk with 100 Ω resistor (some linkers provide switchable internal termination — enable only on last device segment end, NOT on linker end usually)
    • Connect host network (Profibus DP to CI854 or Ethernet to plant switch)
    • In 800xA / S+ Engineering: import EDS/GSD, define linker as FF H1 host; assign devices & schedules
    • Precautions:
      • For IS version: verify Entity parameters (Uo, Io, Po, Co) of linker against field device Ex i certificate — must satisfy: Uo ≤ Umax_device, Io ≤ Imax_device, Po ≤ Pmax_device
      • Do NOT connect AC power to 24 V DC input version — check nameplate
      • H1 trunk shield must be grounded at ONE point (typically at linker end or at drain wire ground — follow FF installation guide: shield drain connected to ground at linker, insulated at field device end)
      • Ensure total device current draw on H1 segment < available power conditioner current (typically 30–90 mA depending on model / cable length)
