Rosemount 702 Wireless Discrete Transmitter 702DX32D1I5WA3WK1B4

The Rosemount 702 Wireless Discrete Transmitter is a robust, battery-powered device designed for monitoring discrete inputs such as dry contacts, switches, or level indicators in industrial environments. Manufactured by Rosemount (an Emerson brand), this model supports WirelessHART protocol for seamless integration into wireless networks, enabling reliable data transmission without the need for wiring. Key applications include process monitoring in oil and gas, chemical plants, water treatment, and manufacturing facilities where discrete on/off signals are critical. Features include dual-channel input for monitoring two discrete points, long battery life (up to 10 years depending on update rates), and hazardous location certifications (e.g., intrinsically safe for Class I Div 1). Advantages over similar products include easy installation with self-organizing mesh networks, reducing cabling costs and downtime, superior reliability in harsh conditions with IP66/67 ratings, and compatibility with Emerson's AMS Wireless SNAP-ON for diagnostics. Drawbacks may include dependency on battery replacement and potential signal interference in densely populated wireless environments. This unit is unused (open box condition), includes mounting bracket and manual, and offers high accuracy for discrete event detection with minimal maintenance.
