Emerson’s New Wireless Transmitter Provides Unprecedented Flexibility for Control and Monitoring of Field Assets

Rosemount 802 Wireless Multi-Discrete Input or Output Transmitter enables remote asset control that helps cut costs, improve safety, and increase productivity

SHAKOPEE, Minn. (Aug. 20, 2024) - Today Emerson announced the release of the Rosemount™ 802 Wireless Multi-Discrete Input or Output Transmitter, which has eight discrete input/output (I/O) channels, each one configurable as an input or an output. WirelessHART® capability allows the transmitter to connect to a wireless gateway, which can in turn link to a host-such as a control system or asset management system-via a wired connection. This allows the host to monitor and control assets remotely over a WirelessHART network.

The new Rosemount 802 transmitter and its predecessor, the Rosemount 702 Wireless Discrete Dual Input or Output Transmitter, are the only WirelessHART-enabled remote I/O transmitters available today, supporting Emerson's vision of a Boundless Automation™ Intelligent Field with flexible configuration and ease of deployment via wireless connectivity.

The wireless capabilities of the new Rosemount 802 dramatically reduce the costs associated with monitoring and controlling field-installed assets, such as motors, valves, and pumps, which traditionally require time-consuming field visits from technicians or a hardwired connection. The new Rosemount 802 minimizes these costs and improves safety by removing the field technician from hazardous areas while maintaining the discrete input and output control levels enabled by the host system.

The new Rosemount 802 functions in a similar manner to Rosemount 702 transmitters, but with eight I/O channels instead of two, each one configurable as a discrete input or output. For installations where multiple assets are located in one area and each must be monitored and/or controlled, the 802 transmitter is a more cost-effective solution than the Rosemount 702.

Power options include 10-30 volt direct current external line power or an Emerson SmartPower™ module. The latter option requires no wiring, provides up to eight years of maintenance-free operation, and can be quickly and easily replaced in the field.

The Rosemount 802 transmitter is certified according to the following safety standards: ATEX Zone 2 Intrinsically Safe, USA Division 2 Non-Incendive and Zone 2 Intrinsically Safe, Canada Division 2 Non-Incendive and Zone 2 Intrinsically Safe, and IECEx Zone 2 Intrinsically Safe. The device enclosure is rated according to NEMA® 4X and IP66.
