Product details

SIPLUS 4AI RTD – extended temperature I/O

Pulls 1.5 W from the 24 VDC bus. Diagnostic alarms and wire-break detection are built in – no extra parameterization needed for the fault reporting.

Supported RTD types and measurement

Covers the common industrial RTD curves: Pt100, Pt200, Pt500, Pt1000, Ni100, Ni120, Ni200, Ni500, Ni1000, Cu10, and LG-Ni1000. Measurement is integrating across three resistance spans (0–150 Ω, 0–300 Ω, 0–600 Ω) to match the sensor full scale. Each input is isolated per the module's IP20 enclosure.

Frequently asked questions
