Overview

The Echoflex Universal Input-Output Interface is the keystone for hybrid control solutions that leverage wireless versatility and wired systems performance. The UIO solves the challenge when it’s not practical to run wires between every device in your building’s control system. The interface includes two inputs and two outputs making it easy to integrate wireless devices with existing panels, wired control systems, or building energy management systems.

The UIO has two hardware input channels which support 0–10 V or 4–20 mA transmitters. Inputs have associated wireless output channels so the analog or digital signal present on the input can be transmitted by different wireless message types. Connected HVAC, building automation, or other third-party wired sensors can have sensor values broadcast wirelessly. In addition to gateways or controllers, another UIO can be linked to reproduce a sensor’s analog or digital value.

Two hardware output channels output 0–10 V or 4–20 mA signals based on wireless devices linked to the channel. Behaving similarly as an Echoflex controller, the output channel interprets a wireless message from a switch, sensor or gateway and outputs an analog value.

The UIO mounts on a DIN rail, fits into a variety of enclosures, or onto a 4x4 electrical box, see accessories section. An external antenna option provides flexible mounting scenarios with no loss in radio signal performance.
