HollySys AW2000 Temperature Transmitter
Multi-input RTD, TC, and mV temperature transmitter with HART 7 and sensor diagnostics.
Product code: AW2000
Brand: Hollysys
Product Overview
The HollySys AW2000 converts RTD, thermocouple, or mV inputs into a standard 4–20 mA signal for control systems. The HART 7 version supports remote configuration and diagnostics. Cold-junction compensation, open/short sensor detection, and input/output isolation improve temperature-loop reliability in industrial environments.
