EMX WEL-200K Wireless Edge Link for Photo Eyes and Safety Edges

The WEL-200 system provides a complete wireless solution for interfacing sensing edges with gate openers and garage door operators. This wireless edge link eliminates the wiring between the safety edge and operator control box ensuring compliance with 2018 UL325 monitoring standards. The WEL-200 operates up to 200 feet line of sight between transmitter and receiver. The receiver connects with up to four transmitters with separate relay and pulse outputs for open and close edge functionality. The transmitter for the WEL-200 is compatible with both 8.2K and 10K monitored safety edges.

WEL-200 systems received a firmware update from EMX in August of 2020, meaning new WEL-200 units are not compatible with WEL-200 units manufactured prior to the update. New circuit boards are colored RED (The old version was green). All units in an installation must be using the same version.
