Allen Bradley 1746-NO4I Analog Output Module, SLC 500, 4 Channels
Allen‑Bradley 1746‑NO4I Product Introduction
The Allen‑Bradley 1746‑NO4I is a 4‑channel analog current output module of the SLC 500 series, designed to convert digital signals from SLC 500 processors into stable and precise analog current signals, which is ideal for controlling current‑driven industrial devices such as actuators, valves, and transmitters in process automation systems. It integrates seamlessly with SLC 500 chassis, providing reliable analog current output capabilities.
Core Features of 1746‑NO4I
- 4 Independent Channels: 4 channels support multiple current output ranges (0‑20mA, 4‑20mA, 0‑21mA), meeting diverse industrial control needs.
- High Precision Conversion: 14‑bit resolution (2.56 μA/count) with R‑2R ladder network DAC conversion, delivering ±0.298% full‑scale accuracy at 25°C and ±0.541% at 60°C, ensuring precise signal output.
- Fast Response & Flexibility: 2.5ms step response (5 to 95% of full scale) for real‑time control; supports 0‑500Ω load range and 5% over‑range capability (0‑21mA) for flexible application scenarios.
- Dual Power Options: Selectable internal backplane power or external 24VDC power (24 ±10% VDC, max 195mA), reducing backplane power consumption and enhancing system flexibility.
- Practical Protection & Monitoring: 500V AC/710V DC isolation between backplane and field wiring; LED status indicators for easy troubleshooting and maintenanceRockwell Automation.
