Allen-Bradley 1746-NO8V: Precise Voltage Signals for Seamless Industrial Control
Allen‑Bradley 1746‑NO8V Product Introduction
The Allen‑Bradley 1746‑NO8V is an 8‑channel analog voltage output module belonging to the Allen‑Bradley SLC 500 series, developed by Rockwell Automation. It is dedicated to converting digital signals from SLC 500 processors into precise analog voltage signals, enabling accurate control of voltage‑driven industrial equipment in process automation and motion control systems. It seamlessly integrates with SLC 500 chassis, providing reliable and flexible analog output capabilities.
Core Features of 1746‑NO8V
- Multi‑channel & Flexible Output Ranges: 8 individually configurable channels support a wide range of voltage outputs (±10V DC, 0‑10V DC, 0‑5V DC, 1‑5V DC), meeting diverse voltage control requirements of industrial devices.
- High Precision & Fast Response: Features 16‑bit resolution (320 µV/count) with R‑2R ladder network DAC conversion, delivering 0.1% full‑scale accuracy at 25°C and 0.2% at 60°C. It has a fast output step response (1 ms for 0‑95% full scale) and channel update times (5 ms for class 1, 10 ms for class 2) for real‑time control.
- Robust Isolation & Protection: Offers 500V DC isolation between the backplane and field wiring, along with output short‑circuit protection and programmable data limits, ensuring stable operation in harsh industrial environments.
- Simplified Maintenance & Monitoring: Factory‑calibrated for out‑of‑the‑box use, with LED indicators for module and channel status monitoring, simplifying troubleshooting and maintenance.
- Broad Compatibility: Fully compatible with SLC 500 chassis and processors, installable in any slot except Slot 0, supporting flexible system configuration.
