Information About 2085-IRT4
The 2085-IRT4 is part of the Allen-Bradley Micro850 series of expansion modules, engineered to add high-resolution temperature sensing capability to Micro800 controllers. The module supports multiple thermocouple types—including B, C, E, J, K, L, N, R, S, and T—as well as a wide range of RTD types such as Pt100, Pt200, Ni618, Ni672, and Cu427. While each channel is individually configurable, the module does not provide channel-to-channel isolation, though reinforced isolation from the system ensures electrical protection. Typical applications include thermal process control, equipment monitoring, environmental regulation, and precision temperature feedback for OEM machine designs.
Key Features:
- Four Temperature Inputs: Supports RTD and thermocouple inputs with 16-bit resolution.
- Isolated Field Interface: Reinforced isolation between module wiring and the controller.
- Wide Sensor Compatibility: Accepts multiple TC types (B, C, J, K, T, etc.) and RTD types (Pt, Ni, Cu).
- Digital Filtering: Provides noise rejection for stable temperature measurements.
- High Accuracy: RTD accuracy ±0.2 to ±0.6°C; TC accuracy ±0.5 to ±3°C depending on type.
- Flexible Ranges: Includes mV and resistance input capability for specialty sensors.
- Compact DIN-Rail Design: Small footprint for Micro850 panel installations.
- Industrial Environment Ratings: Withstands shock, vibration, and –20 to +65°C operation.
The 2085-IRT4 delivers the reliability and precision required for multi-channel temperature monitoring in Micro850 automation systems.
