RTD Temperature Acquisition Module 3CH PT100

The CT-3713 3-channel RTD temperature acquisition module by Sichuan Odot is engineered for high-accuracy industrial temperature monitoring, directly addressing global pain points such as weak RTD signal susceptibility to noise, difficulty supporting both 2-wire and 3-wire PT100 sensors, ground loop interference, and limited field diagnostics. It provides 3 independent PT100 inputs, compatible with both 2-wire and 3-wire PT100 resistance temperature detectors (RTDs), and features built-in lead-resistance compensation for accurate measurements across a wide range (typically –200°C to +600°C).

A key reliability feature is magnetic isolation between the internal backplane bus and field inputs—eliminating ground loops and suppressing common-mode noise, even in electrically harsh environments near VFDs or motors. Each channel includes a dedicated LED indicator for real-time signal status visibility, enabling faster troubleshooting and reduced downtime. 

With a compact footprint, the CT-3713 fits easily into space-constrained control panels. It has been successfully deployed in European pharmaceutical sterilization systems, North American food pasteurization lines, and Southeast Asian HVAC temperature control units, and integrates seamlessly with Siemens, Rockwell, and other major PLC platforms. 

Compliant with CE and industrial EMC standards, the CT-3713 stands out as a high-isolation, plug-and-play PT100 input module that delivers precise, dependable temperature data for global process automation, energy management, and precision manufacturing applications.
