Product Description

CT-3716 6-channel RTD-PT100 Temperature Acquisition Module

Module features

The CT-3716 is a high-precision 6-channel RTD-PT100 temperature acquisition module designed for demanding industrial process control and equipment monitoring applications.

It supports both 2-wire and 3-wire PT100 RTD sensors, automatically compensating for lead-wire resistance to deliver accurate and stable temperature readings over time.

As a premium RTD input module for Industrial Automation, it features magnetic isolation between the field inputs and internal communication bus—providing superior immunity against ground loops and electrical noise commonly found near VFDs, large motors, or welding equipment. This solves critical customer pain points such as signal drift, erratic readings, and system instability in electrically harsh environments.

Equipped with a 15-bit ADC resolution, the module achieves temperature measurement accuracy down to ±0.1°C, making it ideal for industries where thermal precision is non-negotiable—such as pharmaceutical manufacturing, food processing, semiconductor fabrication, and laboratory automation. Each of the six analog input channels includes a dedicated LED status indicator, enabling rapid on-site diagnostics and streamlined maintenance.

The CT-3716 is widely deployed in HVAC Control Systems, chemical reactor monitoring, lithium battery drying ovens, cleanroom environmental tracking, and building energy management systems. As a DIN-rail mountable, ruggedized solution, it serves as a cornerstone for scalable, high-fidelity industrial temperature data acquisition systems in Industry 4.0 architectures.
