Detailed content

Technical Specifications:
  • Channels: 8 independent RTD inputs
  • Sensor Types: Pt100, Cu100, Ni120, 10–3200 Ω
  • Resolution: 14-bit
  • Accuracy: ±0.5 °C typical (Pt100)
  • Isolation: 2500 V AC channel-to-backplane
  • Bus: IONet (10/100 Mbps deterministic Ethernet)
  • Power: From I/O pack backplane, 24 V DC nominal
    Functional Features:​ 2-wire/3-wire selectable; open-circuit detection; high-noise rejection; auto linearization; front LED per channel.
    Materials & Structure:​ Conformal-coated FR-4; metal faceplate; RJ-45 IONet jack; detachable terminal block.
    Working Principle:​ Constant current source excites RTD; voltage drop digitized and converted to temperature via curve table; result published on IONet at control scan rate.
    Installation Requirements:​ Snap into IS220 I/O pack base; shield drain to single point; keep RTD leads away from VFD cables.
    Precautions:​ 3-wire RTD must use matched lead lengths; never mix Pt100 and Cu100 on same module without re-config; avoid loop resistance > cable spec.
