239‑RTD‑AN

1. Product Title

GE 239‑RTD‑AN‑ Multi‑Channel RTD Temperature Monitor Module

2. Product Overview

239‑RTD‑AN is a microprocessor‑based RTD temperature monitoring module for electric motor and industrial equipment thermal protection applications. It receives resistance signals from Pt100, Ni100 and Cu50 RTD sensors, converts resistance values into accurate temperature readings, and supports configurable high‑temperature alarm and trip thresholds. Galvanic channel‑to‑channel isolation reduces field electrical noise interference; front‑panel LED indicators display run status, fault and alarm conditions for fast on‑site troubleshooting. Widely deployed for motor stator winding, bearing and transformer temperature monitoring in power plants and heavy‑industry control cabinets.
