Rosemount 702 Wireless Discrete Transmitter

Description

The Rosemount 702 Wireless Discrete Dual is an intrinsically safe WirelessHART discrete transmitter designed to bring critical switch points into plant control systems without wiring constraints. By digitizing dry contacts from level switches, safety showers, and valve position limits, this instrument enables real-time facility visibility. TPT24 supplies verified, genuine Emerson instruments with complete technical documentation for global industrial deliveries.

Streamlined Monitoring with the Rosemount 702 Discrete Architecture

Hardwiring discrete contacts across tank farms and sprawling refinery units frequently creates high engineering and maintenance overhead. The Rosemount 702 provides an economical solution by transmitting switch state transitions over a self-healing 2.4 GHz wireless mesh. Operators eliminate the physical degradation associated with aging copper cables while gaining instantaneous alerts on equipment status.

Flexible Dual Inputs and Precision Diagnostic Options

Engineered for industrial versatility, the transmitter accommodates two independent dry contact switch inputs or momentary pulse triggers. An optional integrated LCD display provides local state indicators and diagnostic error codes directly at the installation point. Because it operates within self-organizing network topologies, signal pathways automatically reroute around physical site obstructions.

Industrial Ruggedness and Extended Field Service

Constructed with low-copper aluminum and rated to IP66/NEMA 4X standards, the Rosemount 702 resists aggressive chemical vapors and extreme ambient temperatures from -40 °C to +85 °C. Powered by an intrinsically safe SmartPower lithium module, it achieves up to a decade of reliable operation depending on configured update rates. This endurance drastically cuts maintenance intervals in remote and hazardous locations.
