FL1F SmartRelay

6th-Generation SmartRelay

Intelligently Designed

Over the years, the IDEC FL1F SmartRelay has proven to be a reliable and dependable controller for many control applications requiring limited I/O. Along with its universal voltage, built-in analog inputs, 10 Amp relay outputs, and web server functions, we’ve enhanced it with more features suited for today’s demanding IIoT environments, now and into the future. Controls system will be even smarter and more efficient with these new FL1F SmartRelay features!
