Miller Edge Gem-104 Gate Edge Module

Safety Edge Interface Module for Monitored Gate Systems

The Miller Edge GEM-104 Gate Edge Module converts a hard-wired 10K resistive gate sensing edge into a monitored normally closed output, ensuring compatibility with most UL 325–compliant gate operators manufactured after January 2016. Designed for safety and reliability, it includes power and fault LEDs for easy diagnostics and fits neatly inside most gate operator housings. Its NEMA 4–rated construction provides superior protection against moisture and dust, making it suitable for outdoor and industrial applications.
