Specifications
Modbus Register Map
This RTD input module provides 8 universal RTD channels for accurate temperature measurement across a wide range of sensor types, including Pt1000, Ni1000, NTC (5K, 10K, 15K, 20K with configurable B values), Pt100, Cu100, and Cu50.
Equipped with a 32-bit ARM processor and 16-bit A/D conversion, it offers 0.1°C resolution with a fast 0.15s × 8-channel sampling rate. Data is communicated via RS-485 Modbus RTU, ensuring compatibility with PLCs, RTUs, SCADA, and BMS platforms.
Each channel’s RTD type can be set individually, making it suitable for multi-sensor environments. Compact and DIN-rail mountable, this module is ideal for industrial process monitoring, HVAC, energy systems, cold storage, and environmental applications.
