6-Channel 3-wire RTD Card PT100 and PT1000 for Raspberry Pi Back Panel

Add six 3-wire RTD channels (PT100/PT1000) to your Raspberry Pi Back Panel system for precise, reliable temperature monitoring. The card features true 3-wire compensation, stable excitation, and noise-filtered measurements, with all connections routed cleanly through the Back Panel. Control it via CLI/Python or RS485/MODBUS, and scale by stacking alongside other HOP modules. FEATURES 6 RTD inputs, 3-wire compensation - supports PT100 and PT1000 probes True 3-wire lead compensation per channel to minimize cable resistance error Precision excitation and low-noise front end for stable, repeatable readings Mains-hum rejection (50/60 Hz) and input filtering for noisy environments Back Panel integration - clean wiring via Back Panel terminals; auto slot addressing RS485 / MODBUS RTU support for use with external PLCs (no Pi required) I²C control from Raspberry Pi with command-line tools and Python/C libraries OpenPLC and CODESYS integration options for industrial workflows LED sta
