6ES7331-7KB02-0AB0 New Original Siemens S7-300 Plc Programming Controller module

2. Key Selling Points

1. 8-Channel Universal Analog Input – Wide Application Range:Supports standard voltage (±10V, 0–10V, etc.) and current (4–20mA, 0–20mA) signals, ideal for connecting transmitters and sensors in industrial process monitoring.

2. High Accuracy – Reliable Measurement:Offers 12-bit resolution for voltage inputs and 11-bit plus sign for current inputs, with basic accuracy better than ±0.3%, ensuring precise data acquisition.

3. Individually Configurable Per Channel:Each of the 8 channels can be independently set to voltage or current mode with selectable ranges, providing flexibility for diverse sensor types.

4. Group-Based Galvanic Isolation – Strong Noise Immunity:Features 500V AC isolation between channel groups and from the backplane bus, minimizing ground loops and electrical interference.

5. Integrated Diagnostics with Fault Detection:Supports wire-break detection (current only), limit violation alarms, and self-diagnostics, reporting faults to the CPU for fast troubleshooting.
