Description
ABB DSSA165
- Technical Specifications (typical for S100 AI module):
- Input Channels: 8 differential or 16 single-ended (depending on version / jumper config)
- Input Types: 4–20 mA, 0–20 mA, 0–10 V, ±10 V; TC (J/K/T/E/S/B/R/N); RTD (Pt100, Ni100, Cu100 — 2-/3-/4-wire)
- Resolution: 12-bit or 14-bit A/D (model-dependent; typical ±0.1 % FS accuracy)
- Accuracy: ±0.2 % of full scale (typical for current/voltage); ±1 °C (TC with CJC); ±0.5 °C (RTD)
- Sampling Time: ≈200–400 ms per channel scan (full module)
- Isolation: Chassis-ground isolation ≥500 V DC; channel-to-channel NOT isolated (common-mode within group)
- Cold Junction Compensation: Built-in for TC inputs (sensor on module or remote CJ box)
- Power: From S100 rack backplane (5 V / 24 V DC)
- Indicators: Module Run LED, Error LED; per-channel activity not usual on S100 (group status only)
- Operating Temp.: 0 °C to +60 °C
- Mounting: S100 I/O rack slot (35 mm DIN rail with rack adapter or dedicated S100 chassis)
- Certifications: CE, UL
- Functional Features:
- Software-selectable input type per channel group (via configuration switches or engineering tool)
- Linearization tables for TC/RTD; open-sensor detection for RTD/TC
- Over-range and under-range flags reported to controller
- Scaling (engineering units) performed in controller or optionally in module firmware
- Application Scenarios:
- Process variable acquisition — pressure transmitter (4–20 mA), temperature (Pt100 / TC)
- Tank level (4–20 mA with 2-wire transmitter)
- Flow (differential pressure cell 4–20 mA)
- Retrofit of legacy S100 / MP200 systems in pulp & paper, metals, power
- Material & Structure / Working Principle / Installation / Precautions: Same I/O form factor — insert into rack, configure via Advant Controller programming tool (e.g., AdvaCommand / Configurator). For TC wiring use compensating cable; for RTD use 3-wire minimum. Shield analog cables, ground at one end (cabinet earth). Do NOT mix high-voltage and low-level TC/RTD wiring in same bundle.
