Honeywell 8C-TAIMA1 Analog Input Module 16-Channel Temperature Sensor

Overview

The 8C-TAIMA1 is a precision analog input module designed for accurate temperature measurement using thermocouples and RTDs. It delivers reliable signal acquisition with 16 fully isolated input channels, ideal for integration with Honeywell Experion PKS C300 controllers.

Features

• High Channel Density: 16 isolated inputs allow monitoring multiple temperature points simultaneously.

• Versatile Input Support: Compatible with thermocouples (types J, K, T, E) and RTDs.

• Precision Measurement: Low gain error with superior CMRR and NMRR ensures accurate data capture.

• Robust Isolation: Channel-to-channel and channel-to-shield isolation for interference-free operation.

• Cold Junction Compensation: Maintains thermocouple measurement accuracy under varying ambient conditions.

• Open TC Detection: Ensures fault detection for sensor integrity.

• Industrial Protection: Surge protection compliant with EN 61000-4-5.

• Coated Design: Enhanced resistance to industrial contaminants for long-term durability.
