Dual independent channel controller with build-in Apollon PLC. Harmonia can operate in a stand-alone setup, autonomous or chained with other Cronus components or PCS. Designed for electrical elements operating at either 110 or 230 VAC. Elements can be heating rods or flexible blankets of same voltage as supply voltage. Power control with Solid-State-Relay (SSR) for unlimited lifetime. A version for Peltier element thermal control - like cooling - in development.

Models from 2021 include on both channels the feature of measure if a thermal element consume power or not. As if not mounted, connected, broken, thermo couple problems, lack of liquids, etc. And thus give extra security and info that a check-up is needed.
