Hello guys,
I want to establish a wireless means of communication in a very harsh & rugged environment, could you suggest any cost effective & reliable solution for it.
Also specify hardware component along with it’s model number
I am also not getting network connectivity so that I could have gsm/gprs module in plc.
Also the requirement is such we need omni-directional router, it should not be LOS and have relay based output compatible with 24VDC supply.
I have searched following transmitters listed below, please suggest if any other device is compatible:
I have searched RF modules but TTL compatible devices require rs485 to rs232 converts, increasing hardware components would detotriate ruggedness also I need to get smps for powering RF module. So I want single wireless module might be an iot device or any wireless transmitter like wise-4000 series. If you get any plz send me model number.
Distance is around 3 km, it shouldn’t be LOS.
Wireless I/O from Phoenix Contact is the ideal solution for the wireless transfer of digital or analog I/O signals. The right choice for your I/O communication in process and control technology.
Your advantages
Reduced installation and maintenance costs by eliminating cables
Mobility for mobile or interchangeable automation components, thanks to wireless I/O communication
No operating costs for transmission media, thanks to wear-free wireless technology
Quick and easy startup, thanks to user-friendly installation
I think its not an issue at all. We all use high voltage devices or control panels in oil and gas industries (field) with proper enclosure protection or/and with Purge & Pressurization techniques.
You can do the same to avoid these issues.
You can install any equipment with proper protection standards.
ETC is excited to announce the arrival of our brand new wire replacement system! The Iris Wireless Bridge provides the ability to use Cyclops plunger arrival sensors in industrial applications where wire is not an economically viable or easily attainable option. Designed to replace traditional wire and trenching with plug and play equipment, Iris is a cost-effective, easy to use system that safely enables up to 2 switches per node to be powered and relayed back to a panel-mounted gateway up to ½ mile away. Installation is quick and easy; Simply terminate Cyclops to the Iris Wireless Bridge Plunger Sensor Node and connect the outputs on the Gateway to any standard control system. To get more out of your Iris Wireless Bridge at a single well site, connect an additional switch to the second discrete input to wirelessly monitor pressures or tanks. For use in multi-well applications, connect up to two Cyclops sensors per Node, or use the Modbus interface with additional nodes to expand the number of linked devices.
Looking to connect additional devices, or need a wireless solution for another switch or sensor? The Iris Wireless Bridge comes with a flexible interface to enable a variety of system configurations and applications. The current state of up to 2 switches and a Modbus device connected to each node can be read from the gateway using the integrated Modbus Slave interface, while the Iris Gateway can connect to up to 240 nodes. Additional nodes are available with a range of sensor interfaces including Analog, HART, Modbus, RTDs and Turbine Meters.
