| Input Type | Analog input (supports 4-20 mA DC, 0-10 V DC, or thermocouple/RTD signals, depending on configuration) | 
| Number of Channels | 8 differential channels (common for O3ES series modules, enabling independent signal acquisition) | 
| Signal Resolution | 16-bit (ensures high-precision measurement of weak analog signals) | 
| Input Range (Selectable) | - 4-20 mA DC (current loop signals, typical for industrial sensors) - 0-10 V DC (voltage signals for transducers) - Thermocouple: Type J/K/T/E/R/S (optional, for temperature measurement) - RTD: Pt100/Pt1000 (optional, for high-accuracy temperature sensing) | 
| Accuracy | ±0.1% of full scale (at 25°C ambient temperature, ensuring reliable data collection) | 
| Isolation | Channel-to-channel isolation (2.5 kV AC, 1 minute) and channel-to-system isolation (5 kV AC, 1 minute) – reduces electromagnetic interference (EMI) in industrial environments | 
| Communication Interface | Compatible with ABB’s proprietary bus protocols (e.g., PROFINET, Modbus TCP, or ABB’s AC 800M DCS bus) for data transmission to main controllers | 
| Operating Temperature Range | -40°C to +70°C (extended industrial range, suitable for harsh on-site conditions) | 
| Power Supply | 24 V DC (typical for industrial I/O modules, low power consumption: ~2 W max) | 
| Physical Dimensions (L×W×H) | ~120 mm × 80 mm × 150 mm (compact design for rack-mounted installation in ABB I/O cabinets) | 
| Certifications | CE, UL/cUL, ATEX (optional for hazardous areas), IEC 61000-6-2 (EMC immunity) |
