Rosemount 802 wireless multi-discrete I/O transmitter

The Rosemount 802 Wireless Multi-Discrete Input or Output Transmitter has eight discrete 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 wireless capabilities of the Rosemount 802 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.

Power options include 10–30 VDC 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 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.
