Rosemount™ 802 Wireless Multi Discrete I/O Transmitter

The Rosemount 802 Wireless Multi Discrete I/O Transmitter captures up to 8 nearby I/O points, cutting wiring costs and easing installation.

The Rosemount™ 802 Wireless Multi Discrete I/O transmitter is the premier choice for high density discrete I/O applications. It is the ideal transmitter for obtaining up to eight discrete I/O points in close proximity to each other, which reduces wiring costs and simplifies installation. With the security and reliability of WirelessHART® technology, this transmitter offers access to discrete points that are not connected to the control system due to wiring costs and lack of I/O. The Rosemount 802 Wireless Multi Discrete Transmitter is hazardous-rated, environmentally protected, and is powered with Emerson 701P SmartPower™ Module or by external 10-30VDC line power.
