Key Features

1. High-Accuracy Signal Conversion
   • Factory-calibrated 12-bit resolution ensures precise conversion of analog current signals to digital data, with linearity <1 LSB for consistent measurement integrity.
   • Supports two industry-standard current ranges (4–20 mA and 0–20 mA) to accommodate diverse field devices, with the 4–20 mA range as the default for fail-safe operation.
2. Fast & Efficient Data Acquisition
   • Delivers a 2 ms update rate for all four channels, enabling real-time monitoring of dynamic process variables such as pressure, flow, and temperature.
   • 325 Hz input filter minimizes electrical noise interference, ensuring stable and reliable data transmission in industrial environments with high electromagnetic interference (EMI).
3. Robust Electrical Isolation & Noise Immunity
   • Provides 1500 VDC isolation between the field side and PLC logic side, protecting the PLC from voltage spikes, surges, and common-mode noise.
   • High common-mode rejection (>70 dB) and cross-channel rejection (>80 dB) eliminate crosstalk and external interference, maintaining data accuracy even in electrically noisy environments.
4. Compact & Rugged Industrial Design
   • Compact form factor (65 × 60 × 60 mm) allows for high-density installation in standard PLC racks, optimizing cabinet space.
   • Industrial-grade construction with a wide operating temperature range (0°C to +60°C) ensures reliable performance in extreme manufacturing conditions, including factories, processing plants, and outdoor installations.
5. Easy Integration & Diagnostics
   • Seamless plug-and-play integration with GE Fanuc Series 90-30 PLCs, requiring no additional configuration software for basic operation.
   • LED power indicator provides immediate visual status of module operation, simplifying troubleshooting and maintenance.
   • Supports twisted, shielded instrumentation cable for field connections, further reducing noise and ensuring signal integrity.
