8-Channel High-Density Analog Input – Space Efficient:Integrates 8 independent analog input channels in one module, enabling efficient signal acquisition within limited rack space.
Supports Multiple Standard Analog Signals – Highly Compatible:Configurable for ±10V, ±5V, ±2.5V, 0–10V voltage or 0–20mA, 4–20mA current inputs – compatible with most industrial transmitters and sensors.
High Accuracy and Resolution for Reliable Measurement:Offers 13-bit plus sign (14-bit) resolution with typical accuracy better than ±0.3%, ensuring precise capture of process variables like pressure, flow, and temperature (via transmitter).
Group Isolation for Strong Noise Immunity:Provides 500V AC galvanic isolation between input channels and backplane bus, minimizing electrical noise and ground loop interference.
Individually Configurable Per Channel:Each channel can be independently set to different signal types and ranges in STEP 7 or TIA Portal, enabling flexible mixed-signal applications.
