RTD Temperature Acquisition Module 3 Channels PT1000

The CT-3723 is a high-accuracy 3-channel PT1000 temperature acquisition module, engineered for industrial applications demanding wide temperature range coverage and long-term stability. It supports both 2-wire and 3-wire PT1000 RTD sensors, automatically compensating for lead resistance to ensure precise and drift-free measurements.

 As a robust RTD input module for Industrial Automation, it features magnetic isolation between the field inputs and internal communication bus—delivering exceptional immunity against electrical noise from VFDs, motors, or switching power supplies, thereby eliminating common issues like signal instability or data corruption in harsh environments. With a 15-bit ADC resolution, the module achieves sub-degree Celsius measurement precision, making it ideal for sectors such as new energy (e.g., battery material drying), HVAC control, laboratory instrumentation, and precision manufacturing. Each of the three analog input channels includes a dedicated LED status indicator, enabling instant visual diagnostics and simplified troubleshooting during commissioning or maintenance.

 The CT-3723 is widely deployed in lithium battery production lines, cleanroom environmental monitoring, heat pump systems, and smart building energy management platforms. Designed for DIN-rail mounting and built to industrial standards, this 3-channel PT1000 RTD module serves as a reliable, scalable foundation for high-fidelity industrial temperature data acquisition in modern IIoT and Industry 4.0 architectures.
