Frequently Asked Questions (FAQ)

• What sensors does this module support? It supports a wide range of RTD (Resistance Temperature Detector) sensors including Platinum (Pt100, Pt200, etc.) and Nickel (Ni100, Ni200, etc.) types.
• What is differential input? It measures the voltage difference between two input wires per channel, rejecting common-mode noise for more accurate readings in electrically noisy environments.
• How is wiring configured? It supports 2-wire, 3-wire, and 4-wire RTD connections. Update time and accuracy are best with 4-wire or 2-wire (640 ms).
• What do the many LEDs indicate? They provide per-channel status (green for on, red for fault) plus module-level communication and fault status for easy maintenance.
• What is the conformal coating for? The Humiseal coating protects the circuitry from humidity, dust, and corrosive atmospheres, essential for long-term reliability in industrial settings.
• Is it suitable for hazardous areas? Yes, its FM Class 1 Division 2 and cUL certifications allow its use in designated hazardous locations.
• How is it addressed in the PLC? It uses 9 consecutive input words (18 bytes) in the Quantum PLC's I/O table for data and status from its 8 channels.
