The R-IS-0201M-A module is designed primarily for continuous power control of el. heating, eg for continuous power control of the electric cartridge in the DHW storage tank. The module is equipped with one active PWM output, eg for SSR control for control of DHW heating (controlled consumption of excess PV production), at the same time it is equipped with one analog output for SSR control typically equipped with phase power control. 

The module is also equipped with two analog inputs, typically for measuring the temperature in the storage tank for better temperature control and the ability to make better use of PV production.
