Möhlenhoff Alpha base direct 6 channel, B 21402-06N2 230V


The Alpha Basis direct Standard Plus is the central connection unit of an individual room control for surface temperature control of heating and cooling systems.

The Alpha Basis direct is wired to all system components such as controllers and actuators with minimal effort. The system components are supplied directly via the power supply of the Alpha Basis direct. All switching commands from the controllers are forwarded directly to the connected components via the Alpha Basis direct.

The Standard Plus version has a pump control, connections for a temperature limiter/dew point sensor and an input for a change-over signal. The room temperature can be changed in a time-controlled manner using an external system clock via a reduction channel. It is suitable for systems that use normally closed (NC) ) components. Systems that do not use pump control can also be operated with normally open (NO) components.
