Rosemount™ 702 Wireless Discrete Dual Input Transmitter

Rosemount

The Rosemount™ 702 Wireless Discrete Dual Input Transmitter is a cost-effective and installation-ready device that provides two inputs. 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. Commonly used as a repeater, this device also provides personnel access awareness and can be used for monitoring safety showers and eye wash stations.
