WEL-200 Wireless Edge Link Overview

The WEL-200 system provides a complete wireless solution for interfacing sensing edges with gate and door operators. This wireless edge link eliminates the wiring between the safety edge and operator control box while 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.
