Key Features

1. High‑Precision Signal Conversion
   • Delivers 12‑bit resolution and ±0.1% accuracy for reliable measurement of current‑based sensor signals.
   • Supports two industry‑standard current ranges (4–20 mA / 0–20 mA) configurable via on‑board jumpers.
2. Fast & Synchronous Processing
   • Updates all four channels in 2 ms for real‑time process monitoring.
   • Built‑in 325 Hz input filter reduces electrical noise and ensures stable readings.
3. Robust Isolation & Noise Rejection
   • Provides 1500 V isolation between field wiring and PLC logic to protect against voltage spikes.
   • High common‑mode (>70 dB) and cross‑channel (>80 dB) rejection minimizes interference.
4. Easy Configuration & Integration
   • Two independent range jumpers (channels 1–2 / 3–4) allow flexible range setup.
   • Connects directly to the Series 90‑30 PLC backplane for seamless integration.
   • LED indicator for power and module status monitoring.
5. Industrial‑Grade Reliability
   • Compact, rugged design with wide operating temperature tolerance (0°C to +60°C).
   • Factory‑calibrated and tested for long‑term, maintenance‑free operation.
