Weidmüller UR20-4AI-RTD-HP-DIAG / Lenze W540-C-2E-013 — 4-channel RTD analogue input module, high precision, 16-bit resolution, individual channel diagnostics, PUSH IN, IP20, u-remote system, order no. 2456540000. A 4-channel high-precision RTD analogue input module for the u-remote system, supporting all common resistance temperature detectors (Pt, Ni, Cu10) and resistance sensors across a measurement range of –200°C to +850°C with 16-bit resolution and up to 0.2% FSR accuracy. Each channel is individually parameterisable with 2-, 3- or 4-wire sensor connection, automatic 50/60 Hz suppression, cable-break detection, and individual channel diagnostics. The module electronics supply the connected sensors from the input current path (UIN).
