Allen-Bradley 1734-IR2 2-Channel RTD Input Module

Allen‑Bradley 1734-IR2 is a POINT I/O 24V DC two‑channel RTD input module that provides two single‑ended RTD inputs for temperature sensing in a POINT I/O rack. Each channel accepts RTDs with a nominal resistance in the 0–600 ohm range (for example Pt100 and Pt200 variants), enabling direct connection of common RTD sensors without an additional transmitter. The module is powered from 24 V DC and is designed for DIN‑rail mounted, open‑style installation, compatible with standard POINT I/O chassis. Wiring uses a high‑signal (+) and low‑signal (−) per channel with shield, as documented in the wiring instructions, and provides channel‑level temperature scaling options so the raw RTD resistance can be expressed in °C, °F, °K or a user‑defined scale. As a two‑channel RTD and resistance input card, the 1734‑IR2 sits in the Allen‑Bradley POINT I/O family and is intended for direct sensor interfacing in industrial automation environments using Rockwell Automation controllers.
