Miller Edge Controllers
The Miller Edge FSIS-35P-4 is an intrinsically safe relay controller that works with sensing edges and sensing mats to trigger a response on fault or obstruction.
About Miller Edge Controllers
Sensing edges and sensing mats need a controller to turn a contact into an action. The Miller Edge FSIS-35P-4 is an intrinsically safe relay controller that monitors these devices and initiates a safe response when a fault or obstruction is detected.
Its use extends beyond gates and doors to industrial automation, robotics and facility automation, where a sensing edge or mat guards a moving machine or pinch point. It pairs with the wider Miller Edge sensing edge range and the electrical components used to wire it.
Contractors and facility teams typically order the controller alongside the sensing edges or mats it will monitor, so the full safety circuit is quoted together. For a quote, list the number of edges or mats to be monitored, the equipment they protect, and any existing Miller Edge part numbers on site. Each part is listed separately on your quote.
