Frequently Asked Questions (QA)

Q1: What fieldbus protocol does CI801‑EA use?
A1: It uses Profibus DP‑V1, supporting up to 12 Mbps communication speeds.

Q2: Can I change I/O modules while the system runs?
A2: Yes. Hot configuration (“In Run”) is fully supported, letting you add or remove modules without stopping.

Q3: Does it allow HART communications?
A3: Yes, HART signals pass through transparently to the field—no extra gateway needed.

Q4: What about module supervision?
A4: It supports OSP — Output/Signal Supervision — tracking module health and signaling errors early.

Q5: How much power does it draw?
A5: Typically ~140 mA at 24 V DC, supplying isolated power to S800 I/O modules.

Q6: What are the dimensions and weight?
A6: It measures about 85.8 × 136 × 58.5 mm and weighs approximately 0.30 kg.

Q7: In what environments can it operate?
A7: Designed for industrial use from 0 °C to +55 °C, non‑condensing. Some sources list storage valid to –25 °C.

Q8: What protection standards does it meet?
A8: Rated IP20, meets pollution degree 2, and has G3 corrosion resistance per ISA‑S71.04.

Q9: Where is it made?
A9: Manufactured in Europe—Sweden or Switzerland depending on batch.

Q10: Why choose CI801‑EA?
A10: It’s designed for S800 systems—delivering Profibus DP‑V1 integration, hot configuration, HART pass-through, and reliable diagnostics in one module.
