Emerson 702DX32D1I5WA3WK1B4 Temperature Transmitter

Emerson Rosemount 702DX32D1I5WA3WK1B4 is a two‑channel wireless discrete transmitter in the Rosemount 702 family, designed to relay binary sensor states from dry‑contact inputs to a plant control system. The “DX32” designation signals the dry‑contact input option (measurement option code 32), enabling monitoring of two discrete signals such as switches or fault indicators without requiring analog measurement. This variant is specified as intrinsically safe (FM) for use in hazardous locations, making it suitable for demanding environments like refineries, chemical plants, and other applications where safety approvals matter. The transmitter integrates with Emerson’s Wireless Gateway ecosystem and is operable with common configuration tools such as AMS TREX/Device Configurator, with documented wireless update behavior for models including 702DX32 and 702DX42. The exact part number 702DX32D1I5WA3WK1B4 identifies a specific discrete transmitter configuration within the 702 family and is listed by distributors as part of the Rosemount 702 wireless transmitter lineup. In practice, it serves as a digital signaling device rather than a traditional analog temperature transmitter, transmitting channel states to the control system to support monitoring, alarms, and logic without a 4–20 mA output.
