Iris Wireless Bridge


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 or sensors per node to be powered and relayed back to a panel-mounted gateway up to ½ mile away.


DIN rail mounted Gateway modules are Class I, Div 2 certified for safe operation with your preferred control system. Nodes are Class I, Div 1 certified, providing full flexibility for a variety of safe installation locations.


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. The Iris Gateway can connect to up to 240 nodes, offering ultimate versatility for a variety of system configurations and applications. Additional nodes are available with a range of sensor interfaces including Analog, HART, Modbus, RTDs and Turbine Meters. Configuring Iris is fast, easy, and convenient with Vision software. Contact ETC for more information.


Iris Wireless Bridge Nodes and Gateway are designed to reliably communicate from a distance up to ½ mile using omnidirectional weather resistant antennas. Designed for stable performance in even the most extreme conditions, Iris operates within a temperature range of -40˚C to +60°C (-40°F to +140°F). The circuit board is conformal coated during manufacturing to prevent corrosion from chemicals and moisture in the atmosphere over time, increasing longevity. In addition, Iris Nodes feature long-lasting, field replaceable lithium battery packs with an average life span of up to 3 years* when powering a single Cyclops sensor, or 1.5 years* when powering two Cyclops sensors. A solar option is also available for Iris Nodes; this economical solar panel with integrated battery charger removes the need for battery replacement and allows for operation with devices requiring higher power draw, such as ETC’s Sasquatch Plunger Velocity Sensor.

Iris Parts & Accessories App Notes


The Iris Wireless Bridge provides the ability to use Cyclops plunger arrival sensors in applications where wire is not an economically viable or easily attainable option. 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.ETC Cyclops Hawkeye Plunger Sensor
