ADAM-4115 – Robust 6-Ch RTD Input Module by Advantech

The ADAM-4115 Robust 6-Channel RTD Input Module from Advantech is an industrial-grade RS-485 remote I/O device engineered for precise temperature measurement in demanding environments. This versatile module accepts inputs from six differential RTD channels supporting Pt100, Pt1000, Balco 500, and Ni 518 sensors in both 2-wire and 3-wire configurations. With temperature measurement ranges spanning from -200°C to 600°C depending on sensor type, and support for both IEC 60751 ITS90 and JIS C 1604 RTD standards, the ADAM-4115 delivers exceptional flexibility for diverse temperature monitoring requirements. The module achieves ±0.1% typical accuracy with 120 dB common mode rejection at 50/60 Hz, ensuring reliable measurements even in electrically noisy industrial settings. Selectable sampling rates of 10 or 100 Hz across all channels accommodate both high-speed monitoring and power-efficient operation. Built for harsh conditions, the ADAM-4115 operates across an extended temperature range of -40 to 85°C and accepts wide power input from 10 to 48 VDC, making it suitable for process automation, HVAC systems, industrial manufacturing, and critical infrastructure monitoring. Communication is handled via RS-485 with Micro USB interface for configuration, supporting both ASCII command and Modbus/RTU protocols for seamless integration into existing SCADA and PLC systems. Integrated features include burnout detection for open sensor faults and dual watchdog timers for system reliability. The compact design with plug-in terminal blocks simplifies installation and maintenance. CE, FCC, and UL certifications ensure compliance with international standards.
