Information About 1771-IR
The 1771-IR is part of the Allen-Bradley PLC-5 I/O module family and is engineered for precise temperature sensing using resistance temperature detectors. It is constructed as a rack-mountable module that installs directly into a PLC-5 chassis and interfaces with the system backplane without requiring external power. The module supports multiple data formats, including temperature and resistance values, to accommodate different control strategies. It is typically used in process industries where reliable multi-point temperature monitoring is required for control and diagnostics.
Key Features:
- PLC-5 compatible module: Designed specifically for Allen-Bradley PLC-5 systems.
- Six RTD input channels: Enables simultaneous monitoring of multiple temperature points.
- 3-wire RTD support: Improves measurement accuracy by compensating for lead resistance.
- 16-bit resolution: Provides high-precision temperature data.
- Multiple data formats: Supports binary, temperature, and resistance-based readings.
- Rack-mounted design: Installs directly into a PLC-5 chassis.
- No external power required: Powered through the PLC backplane.
- Fast channel update rate: Supports responsive temperature monitoring.
- Industrial-grade construction: Suitable for continuous operation in control environments.
The 1771-IR delivers the reliability and precision required for accurate temperature monitoring in PLC-5-based industrial automation systems.
