Product Description

Product Description

Rosemounte 702 Wireless Discrete Transmitter

In the ever - evolving landscape of industrial automation and monitoring, wireless technology has emerged as a game - changer. The Rosemounte 702 Wireless Discrete Transmitter, developed by Emerson, is a prime example of how wireless solutions are revolutionizing the way industries operate. This transmitter is designed to address the challenges associated with accessing and monitoring discrete points in industrial processes, especially those that have been traditionally difficult or costly to connect to the control system due to wiring constraints.
The Rosemounte 702 Wireless Discrete Transmitter offers a cost - effective, reliable, and secure way to integrate discrete sensors and switches into the overall industrial control infrastructure. By leveraging advanced wireless communication protocols, it enables seamless data transfer from remote or hard - to - reach locations, opening up new possibilities for process optimization, enhanced safety, and improved efficiency across a wide range of industries.
The Rosemounte 702 is compactly designed, making it easy to install in various industrial settings. Its enclosure is typically made of a durable material, such as polybutylene terephthalate (PBT) polymer, which provides protection against environmental factors like dust, moisture, and mild chemical exposure. The use of PBT also contributes to the transmitter's lightweight nature, while still maintaining structural integrity.

2. Technical Features and Functionality

2.1. Wireless Communication Protocol
The Rosemounte 702 Wireless Discrete Transmitter utilizes the WirelessHART® technology, which is a leading standard in industrial wireless communication. WirelessHART offers several advantages that make it well - suited for industrial applications. Firstly, it is highly secure, using advanced encryption algorithms to protect data during transmission. This is crucial in industrial settings where the integrity and confidentiality of process data are of utmost importance.
Secondly, WirelessHART provides a high level of data reliability, delivering over 99% data integrity. It achieves this through techniques such as self - healing mesh networking. In a mesh network, each transmitter can act as a router, relaying data from other transmitters to the gateway. If one communication path is blocked or fails, the network can automatically find an alternative route, ensuring continuous data transfer.
The communication range of the Rosemounte 702, depending on the antenna option selected, can cover significant distances. This allows for the monitoring of discrete points in remote areas of an industrial plant without the need for extensive and costly wiring. The transmitter can communicate with a WirelessHART gateway, which then relays the data to the central control system. The data transfer rate is also optimized to ensure that real - time information is available to the operators for effective process control.
2.2. Input and Output Capabilities
The Rosemounte 702 comes with single or dual - channel capacity, providing flexibility in connecting different types of sensors and switches. It can take input from a variety of non - powered switch types, such as pressure switches, flow switches, and level switches. This means that it can be easily integrated into existing industrial processes where these types of switches are already in use.
For example, in a water treatment plant, pressure switches are used to monitor the pressure in pipelines. The Rosemounte 702 can be connected to these pressure switches to wirelessly transmit the status (open or closed) of the switches to the control system.
When used in output mode, the device can be used for simple control functions. For instance, it can be configured to activate an alarm or a relay - based control system in response to a specific input. 

2. Installation

2.1. Mounting
The Rosemounte 702 is designed for easy installation. It can be mounted in various ways depending on the application requirements. For wall - mounting, the transmitter comes with mounting holes that allow it to be securely fastened to a flat surface using screws or bolts. In some applications, it may be mounted on a pipe or a railing. In such cases, appropriate mounting brackets can be used to attach the transmitter to the pipe or railing.
The installation location should be carefully selected to ensure optimal performance. The transmitter should be installed in a location where it has a clear line of sight to the WirelessHART gateway, or in a position where the antenna can effectively communicate with other nodes in the mesh network. It should also be installed in an area that is easily accessible for maintenance and calibration, if required.
2.2. Wiring and Connection
When connecting sensors or switches to the Rosemounte 702, the process is relatively straightforward. The transmitter is designed to be compatible with a variety of non - powered switch types. The wires from the sensors or switches are connected to the appropriate terminals on the transmitter. The wiring should be done in accordance with the electrical safety standards applicable to the industrial environment.
For example, in a hazardous area, the wiring should be insta lled using explosion - proof conduits and fittings. The connection of the power module is also simple
2.3. Configuration
Configuring the Rosemounte 702 involves setting up parameters such as the sampling rate, the communication protocol settings, and the input/output mapping. The configuration can be done using a handheld configurator or through software installed on a laptop or a control system. The user - selectable sampling rate, ranging from 1 second to 60 minutes, can be set according to the specific needs of the industrial process.
The communication protocol settings, such as the network ID, channel number, and security keys, need to be configured to match the WirelessHART network in the industrial plant. The input/output mapping is used to define which input channels are connected to which sensors or switches and how the output channels are to be used for control functions. Once the configuration is complete, the transmitter can be commissioned and start transmitting data wirelessly.
