Rosemount 702 Wireless Discrete Transmitter Emerson’s Smart Wireless Solution IEC 62591 (WirelessHART®)... the industry standard Self-organizing, adaptive mesh routing  No wireless expertise required, network automatically finds the best communication paths The self-organizing, self-healing network manages multiple communication paths for any given device. If an obstruction is introduced into the network, data will continue to flow because the device already has other established paths. The network will then lay in more communication paths as needed for that device. Emerson’s Smart...

Rosemount 702 Wireless Discrete Transmitter Table 5. Dual Input, Opposing Contact Logic Momentary discrete inputs, measurement option code 32 and 42 The Rosemount 702 is capable of detecting momentary discrete inputs of 10 millisecond or more in duration, regardless of the wireless update rate. At each wireless update, the device reports current discrete state along with an accumulating count of close-open cycles for each input channel. Input Switch State Variable reporting and mapping The Rosemount 702 will report variables exactly like the previous version of the device (measurement...

Rosemount™ 702 Wireless Discrete Transmitter - 9

Rosemount 702 Wireless Discrete Transmitter The output switch functionality of the Rosemount 702 requires that the network is managed by a version 3 Smart Wireless Gateway with v3.9.7 firmware, or a version 4 Gateway with v4.3 or higher firmware installed. If two output circuits are connected to a single Rosemount 702 Transmitter with a single power supply, both CH + and CMN terminals must be connected to each output circuit. The negative power supply wires must be at the same voltage and connected to both CMN terminals. Figure 7. Output Circuit Wiring Figure 10. Dual Output Circuits with...

Rosemount 702 Wireless Discrete Transmitter Safety Shower and Eye Wash Monitoring The Rosemount 702 Transmitter can be used to monitor safety showers and eye wash stations by using switch kits provided by TopWorx™, an Emerson company. These kits are ordered as a part of the Rosemount 702 model code and are available for both insulated and un-insulated pipes. These kits contain the switches, brackets and cables that are necessary to install the transmitter to monitor both the safety shower and the eye wash in a single station. Because each has two input channels, one transmitter can be used...
