Product Description

The TA5123-2AI-RTD module is a compact RTD temperature input module designed for precise temperature measurement in industrial applications. It features 2 isolated analog input channels compatible with 2/3/4-wire RTD sensors (Pt100, Pt1000, Ni120, etc.), supporting resolutions up to 16-bit for high accuracy. The module operates within a wide voltage range of 12-30 VDC and functions reliably in ambient temperatures from -25°C to +70°C. It integrates seamlessly with industrial control systems via RS-485 Modbus RTU communication, enabling direct connectivity to PLCs, HMIs, or SCADA networks. Designed for process control, HVAC, and manufacturing industries, its key advantages include robust EMI immunity, configurable sampling rates, and DIN-rail mounting compatibility. Limitations include no built-in display or battery backup. Screen-free and battery-free, this module prioritizes industrial-grade durability and stability. Typical detection ranges span -200°C to +850°C, varying by sensor type and calibration.
