ADAM-4015 – 6-ch RTD Module with Modbus by Advantech

The ADAM-4015 from Advantech is a robust 6-channel RTD input module engineered for accurate temperature sensing in demanding industrial environments. This RS-485 based I/O module provides six differential input channels supporting 2 and 3-wire RTD connections, accommodating multiple RTD types including Pt 100, Pt 1000, Balco 500, Ni 50, and Ni 508 sensors across various temperature ranges from -200°C to 600°C. The module delivers exceptional measurement accuracy of ±0.1% typical with a common mode rejection ratio of 120 dB at 50/60 Hz, ensuring reliable readings even in electrically noisy environments. Communication flexibility is provided through support for both ASCII command and Modbus/RTU protocols over the RS-485 interface, enabling seamless integration with diverse automation systems and SCADA platforms. The integrated burnout detection feature alerts operators to sensor failures, enhancing system reliability and reducing downtime. A system watchdog timer with 1.6-second timeout and communication watchdog ensure continuous operation. The ADAM-4015 operates on an unregulated 10 to 30 VDC power supply with low power consumption of just 1.2 W, making it energy efficient for distributed installations. Certified to CE, FCC, and UL Class I Division 2 standards, this module is approved for deployment in hazardous locations where flammable gases or vapors may be present. The compact design with plug-in terminal blocks accepting 14 to 28 AWG wire simplifies installation and maintenance. Ideal for process control, building automation, HVAC monitoring, and industrial machinery temperature sensing applications across manufacturing, energy, and critical infrastructure sectors.
