Information About 1756-IR12
The 1756-IR12 is part of the ControlLogix Bulletin 1756 platform and serves as a non-isolated RTD input module suitable for diverse temperature monitoring tasks. It supports configurable input ranges—from 1 to 500 Ω up to 8 to 4000 Ω—allowing compatibility with a broad set of RTDs and sensor types. The module includes built-in digital and notch filtering, sensor offset functions, and detection of wire-off or under/over-range conditions to enhance reliability. Typical use cases include process control, equipment monitoring, and industrial temperature measurement where multi-channel RTD acquisition is required within a chassis-based automation system.
Key Features:
- 12 RTD channels: Supports 3-wire RTD connections for temperature measurement.
- High-resolution conversion: 24-bit data resolution for precise sensing.
- Multiple resistance ranges: Compatible with 500–4000 Ω RTD measurement spans.
- Integrated diagnostics: Wire-off, under/over-range, and sensor offset capabilities.
- Status indication: Front-module LED for operating and fault status.
- Chassis-mounted design: Fits seamlessly into ControlLogix backplanes.
- Reinforced insulation: 250 V continuous isolation rating for safe operation.
- Flexible filtering: Digital and notch filter options for noise reduction.
The 1756-IR12 delivers the reliability and precision required for multi-channel RTD temperature acquisition in ControlLogix automation systems.
