The power supply for the valve drives can be 24…230 V AC/DC. The connection to the ABB i-bus is established using the front side bus connection terminal. The assignment of the physical addresses as well as the parameterization is carried out with Engineering Tool Software ETS from version ETS3.0f...
Device technology Device technology ES/S 4.1.2.1 The Electronic Switch Actuator ES/S 4.1.2.1 is a modular installation device in Pro M design. The device features four semiconductor outputs for control of thermoelectric valve drives in heating and cooling systems. The outputs can be operated with either DC or AC voltage (24…230 V AC/DC).
® The ABB i-bus Electronic Switch Actuator ES/S 4.1.2.1 is a modular instal- lation device for quick installation in the distribution board on 35 mm mount- ing rails to EN 60 715. The mounting position can be selected as required.
The application program is available in the ETS3 at ABB/Heating/Ventilation/Air conditioning/Electronic Switch Actuator. The following chapter describes the parameters of the ES/S 4.1.2.1 using the parameter windows. The parameter window features a dynamic struc- ture, so that further parameters or communication objects may be enabled depending on the parameterization and the function of the outputs.
