Information About 1734-IR2
The 1734-IR2 is part of the Allen-Bradley POINT I/O family, engineered for modular and space-saving distributed I/O. It supports two RTD/resistance inputs with 16-bit resolution using a Delta Sigma analog-to-digital converter, offering a precision of 9.5 mΩ/count or 0.03 °C/count (Pt385 at 25 °C). The module accepts standard RTD sensor types including Pt100, Pt200, Cu10, Ni100, and Ni120, as well as direct resistance inputs from 0 to 600 Ω. It provides absolute accuracy of ±0.1% full scale at 25 °C and allows selectable data formats in Celsius, Fahrenheit, Kelvin, Rankine, or custom scaling. With alarm functions for open-wire, over-range, under-range, and high/low limits, the 1734-IR2 ensures reliable diagnostics. Consuming 220 mA from the POINTBus at 5 VDC, it dissipates up to 1 W of power and is designed for operation in temperatures from –20 to 55 °C. Compatible with terminal bases 1734-TB, TBS, TOP, and TOPS, the module integrates seamlessly into distributed I/O networks.
Key Features:
- Design: Compact POINT I/O input module for RTD and resistance signals.
- Channels: Two single-ended, non-isolated input channels.
- Sensor Support: Compatible with Pt100, Pt200, Cu10, Ni100, and Ni120 RTDs.
- Input Range: Direct resistance measurement from 0 to 600 Ω.
- Resolution: 16-bit with Delta Sigma A/D conversion (9.5 mΩ/count, 0.03 °C/count).
- Accuracy: ±0.1% of full scale at 25 °C (77 °F).
- Data Formats: Selectable outputs in °C, °F, Kelvin, Rankine, or custom scale.
- Diagnostics: Built-in alarms for open-wire, under/over-range, and high/low conditions.
- Power Requirements: 220 mA POINTBus current at 5 VDC, 1 W max power dissipation.
- Environmental Ratings: Operating range –20…55 °C, 30 G shock, 5 G vibration, 5–95% RH non-condensing.
The 1734-IR2 delivers precise temperature and resistance measurement with the flexibility and reliability required in distributed industrial automation systems.
