Key Functional Features
-
8-Channel Multi-Sensor Compatibility
Supports eight independent input channels, each configurable for common RTD types including Pt100, Cu10, Ni100, and Ni120. This versatility allows deployment across diverse temperature monitoring scenarios with mixed sensor types.
-
3-Wire Connection with Lead Resistance Compensation
Utilizes a 3-wire configuration to eliminate errors caused by resistance in long connecting cables. This feature ensures measurement accuracy remains consistent, even over extended cable runs in large industrial plants.
-
High-Precision Signal Conversion
Equipped with a 14-bit ADC for high-resolution data conversion. The module performs on-board linearization and direct conversion of resistance values to engineering units (°C or °F), reducing processing load on the main controller.
-
Per-Channel Individual Configuration
Each channel offers independent software configuration for sensor type, temperature range, filtering, and alarm limits. This granular control maximizes flexibility and optimizes performance for specific process requirements.
-
Advanced Diagnostic & Fault Detection
Integrates comprehensive self-diagnostics for all inputs, actively monitoring for open-circuit, short-circuit, and grounded sensor conditions. Faults are signaled via LEDs and reported to the control system, enabling predictive maintenance and rapid troubleshooting.
-
Industrial-Grade Noise Rejection
Features exceptional Common-Mode Rejection Ratio (CMRR) and Normal-Mode Rejection Ratio (NMRR) at 50/60 Hz, effectively filtering out electromagnetic interference (EMI) from industrial power networks and ensuring stable, clean signal acquisition.
-
Robust Isolation & Safety
Provides galvanic group isolation between input channels and the Modulebus. This protects the control system from electrical transients, prevents ground loops, and enhances operational safety in complex industrial environments.
-
Configurable Digital Filtering
Offers software-selectable digital filters, including a notch filter for 50 Hz or 60 Hz. This suppresses periodic electrical noise, producing smooth, stable temperature readings critical for precise process control.
-
Hot-Swappable Design
Designed for safe installation and removal while the system is powered on (hot-swappable). This minimizes process downtime during maintenance, module replacement, or system expansion.
