Technical Parameters
High-Density Analog Output
Provides 8 channels of ±10V DC voltage or 0–20mA current output with 15-bit resolution (including sign bit).
Active Channel Isolation
Individual galvanic isolation (500V AC) between channels and backplane, compliant with IEC 61131-2 Type 1.
Load-Independent Stability
Maintains ±0.1% full-scale accuracy across 0–500Ω loads for voltage outputs and 0–750Ω for current outputs.
Dynamic Response Compensation
Auto-adjusts slew rate (0.1–10 V/ms programmable) to prevent overshoot in PID control loops.
Intrinsic Safety Compliance
Supports [Ex ia] IIC T4 certification for hazardous areas when paired with IS barriers (FM/ATEX/IECEx).
Multi-Range Diagnostics
Detects wire breaks, short circuits, and ground faults per channel with <10μs response latency.
EMC Robustness
Withstands 10V/m RF interference (80MHz–1GHz) and 4kV surge pulses per EN 61000-6-2/4.
