Key Features

1. Four Isolated Current Output Channels
   • Provides 4 fully isolated channels to eliminate ground loops and crosstalk, ensuring stable, accurate outputs in electrically noisy environments.
   • Each channel is independently configurable for 0–20 mA or 4–20 mA, supporting a wide range of field devices.
2. 14-Bit High-Resolution & High Accuracy
   • Delivers 14-bit resolution (13 bits + sign) for precise, fine-grained control of analog parameters.
   • Maintains ±0.1% full-scale accuracy (4–20 mA) for consistent performance in closed-loop control systems.
3. 2000 VDC Isolation & Noise Immunity
   • Reinforced 2000 VDC isolation between channels and backplane protects the PLC from high-voltage transients and improves system safety.
   • High CMRR (>60 dB) and noise immunity (>10 V RMS) ensure stable operation in harsh industrial environments.
4. Compact, Rugged Industrial Design
   • Ultra-compact 90 × 30 × 25 mm form factor saves panel space and simplifies installation in standard PLC racks.
   • Industrial-grade components and vibration-resistant construction withstand shock, EMI, and extended temperature ranges (0°C to +60°C).
5. Seamless Integration with GE Fanuc 90-30 PLC
   • Designed for direct plug-in compatibility with GE Fanuc Series 90-30 PLC systems, requiring no additional adapters.
   • Communicates via the PLC backplane bus with simple configuration, enabling direct control of analog devices from the PLC program.
