Smart Wireless Field Link specifications

Installation notes

Install the redundant Smart Wireless Field Links in a location that allows for the maximum cable length to the WirelessHART I/O Terminal Block (200 m) and provides good coverage for the wireless field network. Install the redundant Smart Wireless Field Links' antennas at the same height and space them between 1 m to 3 m apart (3 to 9 feet) horizontally. This ensures that the antennas provide identical coverage for the wireless field network and helps to eliminate a coverage gap in the event of a switch over.
The Smart Wireless Field Link:
- receives power from the WirelessHART I/O Card through the WirelessHART I/O Terminal Block and communicates with the WirelessHART I/O Card through an RS485 shielded twisted pair connection.
- communicates with wireless field devices through the WirelessHART protocol.
- supports redundancy.
The Smart Wireless Field Links' antenna can rotate 90° as shown in the image.
