Allen Bradley 1734-IR2K — Detailed Technical Overview (POINT I/O RTD Input Module, Conformal Coated Version)
1. Product Overview
The Allen Bradley 1734-IR2K is a 2-channel RTD (Resistance Temperature Detector) input module designed for accurate temperature measurement in distributed industrial automation systems. This version is typically distinguished by its enhanced environmental protection (conformal coating), making it suitable for harsher industrial environments where humidity, dust, or corrosive elements may be present.
The module is engineered to process resistance-based temperature signals from RTD sensors such as Pt100, Pt200, Pt500, and Pt1000. It converts resistance values into precise temperature readings, supporting applications where thermal stability and measurement accuracy are critical.
Integrated into a POINT I/O system, the module communicates through a backplane and connects to a controller via a network adapter. Its compact design allows it to be installed close to field devices, minimizing signal degradation and improving overall system performance.
