STT650 Temperature Transmitter
The Honeywell SmartLine STT650 is a DIN-Rail-mounted, universal-input temperature transmitter designed for high-accuracy, high-stability measurement across a wide range of process and ambient conditions.
The Honeywell SmartLine® STT650 is a DIN-Rail-mounted, universal-input temperature transmitter engineered for high-accuracy and high-stability measurement across a wide range of process and ambient conditions. Single or dual-channel options save panel space, and a full set of digital protocols (HART 7, FOUNDATION™ Fieldbus, PROFIBUS PA) make it a drop-in modernization for legacy panels.
