8-Channel Universal Analog Input with High Integration:Provides 8 configurable input channels in one module, supporting voltage, current, RTD, and thermocouple (TC) signals – ideal for complex process signal acquisition.
Direct Connection to RTDs & Thermocouples – Cost-Efficient:Accepts direct input from Pt100, Ni100 RTDs or J/K/T/E/R/S/B/N type thermocouples, with built-in cold-junction compensation and linearization, eliminating the need for external transmitters.
High Accuracy and Resolution for Precise Measurement:Offers up to 15-bit plus sign (16-bit) resolution, with typical accuracy better than ±0.3%, ensuring reliable and accurate data capture for critical process variables.
Galvanic Isolation Between Channels and Bus:Features 500V AC isolation between channels and backplane bus, minimizing noise interference and enhancing system stability and safety.
Individually Configurable Per Channel:Each channel can be independently set for signal type, range, and filter settings in STEP 7 or TIA Portal, enabling flexible mixed-signal applications.
