• Power loss: Typical 2 W, ensuring energy-efficient operation.
• Analog inputs: 16 channels for voltage or current measurement, with destruction limits of 20 V DC (permanent) and 40 mA (max.).
• Input ranges (voltage): 1–5 V (100 kΩ), ±1 V (10 MΩ), ±10 V (100 kΩ) – all supported.
• Input ranges (current): ±20 mA and 4–20 mA with 50 Ω input resistance.
• Cable length: Shielded cables up to 200 m max.
• Resolution: 13-bit with overrange, including sign.
• Integration time: Parameterizable; basic conversion time 55/65 ms; integration time 50/60 ms.
• Interference suppression: For 50/60 Hz, ensuring stable readings in noisy environments.
• Module execution time: 880/1040 ms (all channels released).
• Temperature error: ±0.01 %/K (relative to input range).
• Operational error limits: ±0.65 % for voltage (1.0 % for 1–5 V) and current; basic error limit ±0.25 % (0.5 % for 1–5 V).
• Diagnostics: No diagnostics function; non-isolated channels and no potential separation between channels, backplane bus, or load voltage.
• Isolation tested: 500 V AC / 707 V DC (type test).
