CT-3734: RTD Temperature Acquisition Module

Remote I/O System Series C

The Series C is a modular remote I/O system consisting of a network adapter and extended I/O modules.

The CT-3734 is specifically designed for temperature acquisition using RTD sensors such as Pt100, Pt200, Pt500, and Pt1000. It features 3 analog input channels for precise temperature monitoring with support for three-wire configurations.

Features

• Supports 3 independent RTD input channels.
• High-accuracy temperature measurement ranging from -200°C to 850°C (depending on the RTD type).
• Compatible with multiple RTD standards: Pt100, Pt200, Pt500, Pt1000.
• Optoelectronic isolation between the internal bus and field input for enhanced safety.
• LED indicators for each channel, enabling easy status monitoring.
• Configurable sampling time to meet various application needs.
