F8650E high-performance safety-related analog I/O module

F8650E is a high-performance safety-related analog I/O module under HIMA’s HIQ series, specifically designed for fail-safe control systems in industrial safety-critical scenarios. It focuses on high-precision acquisition of analog signals (e.g., pressure, temperature, flow) and reliable analog output control, with core advantages in safety certification, anti-interference performance, and harsh environment adaptability. It is a key component of Safety Instrumented Systems (SIS) in industries such as petrochemicals, power, and nuclear energy. Below is its integrated detailed information:

Parameter Category	Specific Details
Channel Configuration	- Analog Input (AI): 8 independent isolated channels, supporting 4–20mA DC (two-wire/three-wire transmitters), 0–20mA DC (current signals), and 0–10V DC, 1–5V DC (voltage signals); 16-bit ADC resolution ensures high-precision signal conversion.- Analog Output (AO): 4 independent isolated channels, supporting 4–20mA DC, 0–20mA DC, 0–10V DC; 16-bit DAC resolution for stable control signal output.- Isolation: Channel-to-channel isolation ≥1500V DC (1 minute); Module-to-backplane isolation ≥2500V DC (1 minute); effectively suppresses ground loops and cross-interference between multi-channel signals.
Accuracy & Signal Performance	- AI Accuracy: ±0.1% full scale (FS) at 25°C; ±0.2% FS over the entire operating temperature range (-40°C to 70°C).- AO Accuracy: ±0.1% FS at 25°C; ±0.2% FS over the operating temperature range.- Temperature Drift: ±0.001% FS/°C; minimizes accuracy loss caused by ambient temperature fluctuations in control cabinets.- Signal Conditioning: Built-in digital filtering (configurable cutoff frequency: 0.1Hz–10Hz), signal linearization, and offset calibration functions; optimizes unstable field signals (e.g., weak signals from thermocouples/RTDs).
