Allen Bradley 1734-IR2 POINT I/O 2 Point RTD Input Module
1734-IR2
- model1 1734-IR2
Manufacturer: Allen Bradley
Adapter Products: 24V DC 2 Point RTD Input Module
The 1734-IR2 is a Resistance Temperature Detector (RTD) input module within Allen-Bradley's POINT I/O product family. It features two single-ended, non-isolated input channels designed to support various types of sensors and analog signals.
Each channel of the 1734-IR2 module can accommodate the following RTD sensor types: 100 Pt α = 0.00385; 200 Pt α = 0.00385; 100 Pt α = 0.003916; 200 Pt α = 0.003916; 10 Cu α = 0.00427; 100 Ni α = 0.00618; 120 Ni α = 0.00618; and 120 Ni α = 0.00672. Additionally, aside from RTD sensor inputs, this module also supports direct wiring of 0-600 Ω analog signals.
With a 16-bit resolution, the 1734-IR2 module provides accurate and precise measurements, making it suitable for a wide range of industrial temperature sensing applications.
