Key Features

1. High‑Density 16‑Channel Design
   • Integrates 16 independent input channels in one compact unit, saving cabinet space and reducing system cost.
2. Flexible Software‑Configurable Ranges
   • Each channel can be set to 4–20 mA, 0–20 mA, or 4–20 mA Enhanced to match various transmitter types.
3. Open‑Wire Fault Detection
   • The Enhanced 4–20 mA mode detects broken wires or sensor failures, triggering alarms to prevent data loss.
4. High Precision & Fast Response
   • 12‑bit resolution and 13 ms total update rate deliver accurate, timely data for closed‑loop control.
5. Strong Noise Immunity
   • Channel‑to‑PLC isolation (1500 VAC) protects against electrical interference in harsh industrial environments.
6. LED Diagnostic Indicators
   • Built‑in ON/OFF/FAIL LEDs simplify status monitoring and on‑site troubleshooting.
