ABB PPD113A01-10-150000

Product Brief:​ The PPD113A01 (commonly called PS13 or PPD unit​ in S800 I/O context) is the power distribution and termination base​ for an S800 I/O rack (TU830/TU842 etc.). It mounts on the left side of the I/O terminal unit stack (or as a separate power feed module) and provides:

  • Regulated +5 V DC logic supply​ to the S800 ModuleBus backplane (powers DI/DO/AI/AO module logic)
  • +24 V DC process voltage (UP)​ distribution to the I/O module groups (for 24 V DC digital outputs, analog transmitters, etc.)
  • Terminals for 24 V DC incoming power (redundant A/B feeds), PE, and sometimes alarm relay contact for PSU fail
  • In some versions (like PPD113 with built-in switcher) it contains the 5 V DC switch-mode regulator; in others (PPD115…) it expects external 5 V DC — PPD113A01 typically HAS the internal 5 V regulator.

Description

ABB PPD113A01-10-150000

  • Technical Specifications (typical PPD113A01):
    • Input Voltage: 24 V DC (18–30 V DC) — system / field supply from plant PSU (DSSR122 / third-party 24 V DC PSU)
    • Output Logic (5 V DC): 5 V ±2 %, max 3 A (sufficient for typical S800 rack with 8–10 modules); short-circuit protected
    • Output Process (24 V DC): Pass-through from input (fused or unfused depending on version) — feeds UP terminals on each TU in rack via bus bar or jumper
    • Redundant Input: Dual 24 V DC inputs (A/B) with diode OR-ing — supports N+1 PSU redundancy
    • Alarm Contact: 1 × SPDT relay (NO/NC) — closes on PSU healthy or opens on fail (configurable polarity)
    • Power Dissipation: <10 W (quiescent + load dependent)
    • Mounting: On S800 I/O rack — leftmost or designated power module position; DIN rail or direct bolt to TU end-plate
    • Indicators: Input Power OK (green), 5 V OK (green), Fault (red)
    • Operating Temp.: 0 °C to +55 °C
    • Dimensions: ≈45 mm (W) × 119 mm (H) × 102 mm (D) — matches S800 TU width
    • Certifications: CE, UL, cUL, ATEX Zone 2, marine
  • Functional Features:
    • Eliminates need for separate 5 V DC brick PSU — internal regulator derives 5 V from 24 V DC input
    • Redundant 24 V DC input allows N+1 PSU configuration for high-availability I/O
    • Alarm relay can be wired to DCS DI or annunciator for “I/O Rack Power Fail”
    • Compatible with all S800 I/O modules(DI8xx/DO8xx/AI8xx/AO8xx)
  • Application Scenarios:
    • Every S800 I/O rack requires a PPD unit (or PS13-type power feed) — PPD113A01 is the standard for single/dual 24 V DC supply
    • Redundant PSU feeding (two 24 V DC PSUs → PPD113A01 A/B inputs → I/O rack stays alive if one PSU fails)
    • Retrofit of older S800 rack — replace failed PPD113 or upgrade from external 5 V PSU to integrated version
  • Material & Structure / Working Principle / Installation / Precautions:
    • Mount PPD113A01 on left end of I/O stack (engages with TU end-plate or DIN rail)
    • Connect +24 V DC (A & B if redundant) to terminals observing polarity; connect PE to PE terminal
    • Verify 5 V OK LED illuminates after power-on — if not, check input voltage & fuse
    • Wire UP (process 24 V) from PPD to first TU’s UP terminal; subsequent TUs often link via bus bar
    • Precautions:
      • Total 5 V load = sum of all modules’ logic current (typ. 80–150 mA/module) — PPD113A01’s 5 V regulator rated for typical rack; for very large racks (>12 modules + high-density) verify 5 V current budget — may need PS14 (higher current)
      • Do NOT apply >30 V DC to 5 V terminals — regulator damaged
      • If using redundant PSUs: size each PSU for 100 % load + margin — diode OR means both share load; if one fails other must carry full load
      • Alarm contact wiring: test during commissioning — PSU fail should generate visible alarm in DCS
