Emerson announced the release of the , which has eight discrete input/output (I/O) channels, each configurable as an input or an output. WirelessHART capability allows the transmitter to connect to a wireless gateway, which can 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  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 transmitter functions similarly to Rosemount 702 transmitters, but with eight I/O channels instead of two, each 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.
