Product Description

The AAR145-S50 S1 is a high-density 16-channel temperature measurement module designed for Yokogawa CENTUM VP and ProSafe-RS systems. It supports both thermocouples (TC) and resistance temperature detectors (RTD), delivering digital temperature values directly to the process processor. This eliminates the need for external signal conditioners while maintaining high measurement accuracy.

The module features 16-bit A/D conversion, module-level isolation, and a compact form factor compatible with pressure clamp terminals or MIL cable connections, ensuring robust operation in high-vibration industrial environments. The S1 revision emphasizes reliable electrical interfaces and stable operation under standard industrial conditions.

Technical Specifications

Application Scenarios

The AAR145-S50 S1 is commonly deployed in temperature-critical processes, including:

• Distillation column monitoring

• Furnace and kiln temperature control

• Large-scale HVAC and turbine bearing temperature arrays

Industries include oil & gas, pharmaceuticals, and power generation. Its 16-channel density enables efficient monitoring of large sensor networks while preserving signal integrity.

Frequently Asked Questions

Can this module handle mixed TC and RTD inputs simultaneously?

• Each module or software-configured group is typically dedicated to one sensor type. While the hardware is universal, grouping similar sensors ensures accurate thermal compensation.

Does this module include Cold Junction Compensation (CJC)?

• Yes. When used with a compatible Yokogawa terminal board, the module provides CJC via onboard or terminal-based thermistors, ensuring accurate thermocouple readings.
