Detailed content
- Functional Features: 4 groups independently configurable — each group of 3 channels can be set to different input ranges and signal types; simultaneous sampling eliminates time skew across channels; automatic wire-break detection with fault flag; over-range / under-range alarm; programmable digital filter (0–60 Hz cutoff); per-channel LED status indicator.
- Application Scenarios: Monitoring and control of temperature, pressure, flow, and liquid level in continuous process industries; high-precision data acquisition where simultaneous sampling of multiple process variables is required.
- Material & Structure: Glass-fiber reinforced flame-retardant PC housing; 8-layer PCB with independent analog and digital ground planes; Analog Devices AD7606-class 16-bit SAR ADC; Si86xx digital isolators; ADR4525 ultra-low-drift 2.5 V reference; gold-plated spring-contact terminals; standard 90-30 module size ≈15.9 × 90 × 98 mm; front panel 12 channel LEDs (3 per group); rear 4 groups of terminal blocks (3 inputs + 1 common per group); top module-lock latch.
- Installation & Usage Notes: Install in standard Series 90-30 baseplate; configure each group’s input type via software or on-board settings before wiring; ensure proper grounding of analog shields; verify channel isolation limits (250 VDC max) are not exceeded between channels; perform periodic calibration check to maintain ≤50 ppm/°C drift specification.
