ABB TK801V006

ABB TK801V006

Product Brief:​ The TK801Vnn is the ModuleBus cable​ that provides the high-speed parallel bus connection between an AC 800M controller (PM865/PM866/PM876/PM891 on BC810/BC820) and a local S800 I/O rack​ (TB521/TB511 with I/O modules). It carries:

  • 5 V logic power (derived from CPU baseplate — not from I/O PPD! — though PPD still needed for I/O module process power)
  • Address, data, control lines for cyclic I/O scan
  • The cable is keyed (shrouded 40-pin IDC header) — prevents reverse insertion

    “V006” = 0.6 m length; other lengths available (V001 = 1 m, V002 = 2 m, V005 = 5 m). Maximum reliable length depends on system noise — typically ≤5 m for ModuleBus; keep as short as practicable.

Description

ABB TK801V006

  • Technical Specifications:
    • Connector Type: 2 × 40-pin IDC shrouded header (keyed — pin 1 marked)
    • Cable: 40-conductor flat ribbon, gray PVC jacket; twisted-pair arrangement inside for some signals (per ABB spec)
    • Length: 0.6 m (this variant)
    • Max Recommended Length: ≤5 m (typical install ≤2 m for best signal integrity)
    • Operating Temp.: –20 °C to +60 °C (cable rating –40 °C to +80 °C)
    • Pinout: Proprietary ABB ModuleBus — do NOT substitute generic 40-way IDE cable (pinout differs & shielding inadequate)
  • Functional Features / Application / Material / Structure / Working Principle / Installation / Precautions:
    • Used ONLY for local S800 I/O​ directly cabled to AC 800M CPU — NOT for remote I/O (remote = CI840A + HN800 fiber/copper)
    • Connect one end to BC810/BC820 “ModuleBus” header; other end to TB521/TB511 “ModuleBus” header — ensure pin 1 aligns (ribbon side marked)
    • After connection: power up → I/O modules detected → Run LED on CPU + Com LED on I/O rack indicate healthy scan
    • Precautions:
      • Do NOT fold sharply (<4× cable width bend radius ≈25 mm)
      • Keep away from VFD output cables / power feeders (min 100 mm separation; cross at 90°)
      • If local I/O not detected: check both ends seated, verify PPD113 powered (5 V LED on PPD ON — ModuleBus 5 V comes from CPU but PPD must provide I/O module logic 5 V too), verify no bent pins in header
      • For multiple local I/O racks: can daisy-chain? — No, ModuleBus is point-to-point from CPU to ONE TB521; to have >12 modules local use TB521 with multiple TUs daisy-chained on same ModuleBus (max per TB521 = 12 modules; can add second TU on same backplane if TB521 version supports expansion — some do via bus extender — check S800 rack capacity). If need >1 separate local rack — use remote I/O (CI840A + HN800) for 2nd rack.
